Answer:
The 43kg student will be sliding at 1.79m/s opposite the direction the 34kg student is going.
Explanation:
Conservation of linear momentum!
The law of conservation of momentum says that in an isolated system, the momentum before must equal the momentum after:
[tex]mv_1+m_1v_2=m_1_v_{1f}+m_2v_{2f}[/tex].
For our two students
[tex](32kg)(v_1)+(43kg)(v_2)= (32kg)+(43kg)(-2.4m/s)+(43kg)(v_{2f})[/tex] (notice the - sign in -2.4m/s, this means going to the left)
since the students were not moving at first, [tex]v_1=v_2= 0[/tex], therefore we have
[tex]0= (32kg)(-2.4m/s)+(43kg)(v_{2f})[/tex]
solving for [tex]v_{2f}[/tex] gives
[tex]76.8=(43kg)(v_{2f})[/tex]
[tex]\boxed{v_{2f} = 1.79m/s}[/tex]
Hence the 43kg student will be sliding at 1.79m/s to the right.
Study the scenario.
A magnetic field is generated when using an electromagnet. The events that occur to create the magnetic field are listed below.
The magnetic domains align inside the piece of metal.
Close the circuit so a current flows through it.
Wrap a wire to create loops around a piece of metal, such as iron.
The magnetic field is generated inside the loops.
What is the correct order of events?
1. C, A, B, D
2. A, C, B, D
3. B, A, D, C
4. C, B, D, A
Answer:
4. C, B, D, A
Explanation:
This is a simple experiment to make electromagnets. Electromagnets are the instrument/object which behave like magnet when electricity is passed around them. As long as electricity is supplied they will behave like magnet. When the electricity is stopped, they will no longer behave like magnet.
The correct sequence, as per the question, to make electromagnet are listed below:
Wrap a wire to create loops around a piece of metal, such as iron. (As of now it will not behave like magnet)
As soon as we close the circuit, current starts flowing through the loops and generate magnetic field.
This magnetic field forces the magnetic domains inside metal piece to align and the metal starts behaving like a magnet.
A spinning wheel has a rotational inertia of 2 kg•m². It has an angular velocity of 6.0 rad/s. An average counterclockwise torque of 5.0 N•m is applied, and continues for 4.0 s. What is the change in angular momentum of the wheel?
Answer:
[tex]-20.0 kg m^2/s[/tex]
Explanation:
The angular momentum of an object in rotation is given by
[tex]L=I \omega[/tex]
where
I is the moment of inertia
[tex]\omega[/tex] is the angular speed
In this problem, initially we have
[tex]I=2 kg m^2[/tex] is the moment of inertia of the wheel
[tex]\omega_i = 6.0 rad/s[/tex] is the initial angular speed
So the initial angular momentum is
[tex]L_i = I\omega_i = (2)(6.0)=12 kg m^2/s[/tex]
Later, a counterclockwise torque of
[tex]\tau=-5.0 Nm[/tex] is applied
So the angular acceleration of the wheel is:
[tex]\alpha = \frac{\tau}{I}=\frac{-5.0}{2}=-2.5 rad/s^2[/tex] in the direction opposite to the initial rotation.
As a result, the final angular velocity of the wheel will be:
[tex]\omega_f = \omega_i + \alpha t[/tex]
where
t = 4.0 is the time interval
Solving,
[tex]\omega_f = +6.0 +(-2.5)(4.0)=-4 rad/s[/tex]
which means that now the wheel is rotating in the counterclockwise direction.
Therefore, the new angular momentum of the wheel is:
[tex]L_f = I\omega_f =(2)(-4.0)=-8.0 kg m^2/s[/tex]
So, the change in angular momentum is:
[tex]\Delta L=L_f - L_i = (-8.0-(12))=-20.0 kg m/s^2[/tex]

a uniform disc and hollow right circular cone have the same formula for their moment of inertia when rotating about the central axis why is it so?
Answer:
This is as a result that about the central axis a collapsed hollow cone is equivalent to a uniform disc
Explanation:
The integration of the differential mass of the hollow right circular cone yields
[tex]I=\int\limits dmr^2 = \int\limits^a_b {\frac{2Mxr^2}{R^2 +H^2} } \, dx = \frac{2MR^2dx}{(R^2 +H^2)^2} \frac{(R^2 +H^2)^2}{4} = \frac{1}{2}MR^2[/tex]
and for a uniform disc
I = 1/2πρtr⁴ = 1/2Mr².
Final answer:
Both a uniform disc and a hollow right circular cone have the same formula for their moment of inertia when rotating about the central axis because their shapes and mass distributions result in similar rotational behavior.
Explanation:
Both a uniform disc and a hollow right circular cone have the same formula for their moment of inertia when rotating about the central axis because their shapes and distributions of mass result in similar rotational behavior.
The moment of inertia depends on the distribution of mass around an axis of rotation. In both objects, the mass is distributed symmetrically about the central axis, resulting in similar moment of inertia values.
For a uniform disc, the moment of inertia is given by the formula I = 1/2 MR², where M is the mass of the disc and R is its radius. Similarly, for a hollow right circular cone, the moment of inertia is also given by the formula I = 1/2 MR², where M is the mass of the cone and R is the radius of its base.
It is well known that lightning is seen before the thunder is heard. Wavelengths of electromagnetic and sound waves can be the same. Imagine that the wavelengths from the lightning and thunder are the same, what can be said about their frequencies?
Answer:
Explanation:
Lightning is seen before the thunder is heard because , velocity of light exceeds velocity of sound. We also know that velocity , wavelength and frequency are related as follows
velocity = frequency x wavelength
velocity of light > velocity of sound
frequency of light x wavelength of light > frequency of sound x wavelength of sound
But given wavelength of light = wavelength of sound
Putting this relation in the equation above
frequency of light x wavelength of light > frequency of sound x wavelength of light
cancelling out equal terms on both sides
frequency of light > frequency of sound
frequency of light will be greater than frequency of sound.
Answer:
the frequency of thunder is more than the frequency of lightning
Explanation:
Light waves (lightning) are faster than sound waves (thunder). If their wavelengths are the same, then the frequency of light waves must be larger
What are the two most common ways to produce hydrogen gas used in fuel cells?
Answer:
Steam-methane reforming
Electrolysis of water
Explanation:
Steam methane reforming involves reaction of methane with water in the presence of a catalyst such as nickel to form Carbon oxides and Hydrogen.
CH4 + H2O ⇌ CO + 3 H
Electrolysis of water involves splitting of water through application of electric current to give Hydrogen and Oxygen gas.
2 H2O(l) → 2 H2(g) + O2(g)
Hydrogen gas for fuel cells is commonly produced through steam reforming and electrolysis. In steam reforming, steam is passed over coke to produce hydrogen and carbon monoxide. In electrolysis, water is split into hydrogen and oxygen gases with a power supply.
Explanation:
The two most common ways to produce hydrogen gas used in fuel cells are through steam reforming and electrolysis. Steam reforming involves passing steam over coke at high temperatures, which produces a mixture of carbon monoxide and hydrogen gas, also known as water gas.
In the electrolysis process, water is split into hydrogen and oxygen gases by the addition of energy using a battery or power supply. For fuel cells, hydrogen obtained from these processes is continuously fed into the cell with an oxidant and undergoes redox chemistry that generates electrical energy and water as the waste product. The fuel cell reactions are catalyzed on graphite electrodes embedded with platinum-based catalysts.

what is the resistance of a 20.0 meter long tungsten rod with a cross sectional area of 1.00 times 10^-4 meter^2 at 20C
Answer:
[tex]0.0112 \Omega[/tex]
Explanation:
The resistance of an object tells us how much the object opposes to the flow of current through it.
The resistance of a conductor is given by the formula
[tex]R=\frac{\rho L}{A}[/tex]
where
[tex]\rho[/tex] is the resistivity of the material
L is the length of the conductor
A is the cross-sectional area
For the tungsten rod in this problem, we have:
L = 20.0 m is the length
[tex]A=1.00\cdot 10^{-4}m^2[/tex] is the cross-sectional area
[tex]\rho=5.6\cdot 10^{-8} \Omega \cdot m[/tex] is the resistivity of tungsten at 20C
Substituting into the formula, we find the resistance of the tungsten rod:
[tex]R=\frac{(5.6\cdot 10^{-8})(20.0)}{1.00\cdot 10^{-4}}=0.0112 \Omega[/tex]
A scientist who studies teenage behavior was interested in determining if teenagers spend more time playing computer games then they did in the 1990s. In 1990s, the average amount of time spent playing computer games was 10.2 hours per week. Is the amount of time greater than that for this year? Ten students were surveyed and asked how many hours they spent playing video games. The test statistics is equal to 0.45.What is the p-value?greater than 0.10between 0.010 and 0.025less than 0.001between 0.001 and 0.005between 0.005 and 0.010between 0.025 and 0.05between 0.05 and 0.10
Answer:
greater than 0.10
Explanation:
The null hypothesis is:
[tex]H_{0} = 10.2[/tex]
The alternate hypotesis is:
[tex]H_{1} > 10.2[/tex]
Our test statistic is:
[tex]t = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]
In which X is the statistic, [tex]\mu[/tex] is the mean, [tex]\sigma[/tex] is the standard deviation and n is the size of the sample.
We have that:
[tex]t = 0.45[/tex]
We are testing if X is greater than 0.45, so our pvalue is 1 subtracted by the pvalue of z = t = 0.45.
z = 0.45 has a pvalue of 0.6736
1 - 0.6735 = 0.3264
So our pvalue is 0.3264, which is greater than 0.10.
So the correct answer is:
greater than 0.10
Here the test sta-tis-tics should be greater than 0.10.
Calculation of the test statistics:Since In 1990s, the average amount of time spent playing computer games was 10.2 hours per week.
Here, t = 0.45
So in the case when X is greater than 0.45, so our pvalue is 1 subtracted by the p-value of z = t = 0.45.
z = 0.45 has a p-value of 0.6736
1 - 0.6735 = 0.3264
Now
our p-value is 0.3264, which is greater than 0.10.

Two point charges are fixed on the y axis: a negative point charge q1 = -28 µC at y1 = +0.21 m and a positive point charge q2 at y2 = +0.36 m. A third point charge q = +8.5 µC is fixed at the origin. The net electrostatic force exerted on the charge q by the other two charges has a magnitude of 17 N and points in the +y direction. Determine the magnitude of q2.
Answer:
[tex]1.11\times10^{-4} C[/tex]
Explanation:
Coulomb's force:
[tex]F=\frac{kqq'}{d^2}[/tex]
where, q and q' are two charges, d is the distance between them and k is the Coulomb constant.
The net force on charge q at origin is 17 N.
[tex]17 = 9\times 10^9 \times 8.5\times10^{-6}[\frac{-28\times 10^{-6}}{0.21^2}+\frac{q_2}{0.36^2}]\\17 = 76.5 \times 10^3[-6.35 \times 10^{-4}+7.72q_2]\\q_2 = 1.11\times10^{-4} C[/tex]
Answer:
5.35 x 10^-5 C
Explanation:
q1 = - 28 micro Coulomb =- 28 x 10^-6 C
q2 = ?
q3 = 8.5 micro Coulomb = 8.5 x 10^-6 C
y1 = 0.21 m
y2 = 0.36 m
q3 is at origin.
Let F1 is the force between q1 and q3 and F2 is the force between q2 and q3.
By use of Coulomb's law, the force between the two charges is given by
[tex]F = \frac{Kqq'}{r^{2}}[/tex]
Now, [tex]F_{1} = \frac{Kq_{1}q_{3}}{0.2^{2}}[/tex]
[tex]F_{1} = \frac{9\times 10^{9}\times 28\times 10^{-6}\times 8.5\times 10^{-6}}{0.21^{2}}[/tex]
F1 = 48.6 N .... (1)
Now, [tex]F_{2} = \frac{Kq_{2}\times q_{3}}{0.36^{2}}[/tex]
[tex]F_{2} = \frac{9\times 10^{9}\times q_{2} \times 8.5\times 10^{-6}}{0.36^{2}}[/tex]
F2 = 590277.78 q2 .... (2)
Now, F1 - F2 = 17
48.6 - 590277.78 q2 = 17 from (1) and (2)
q2 = 5.35 x 10^-5 C
Thus, the charge on q2 is 5.35 x 10^-5 C.
Compare and contrast absolute dating and relative dating.
Answer:
Relative dating involves the dating of geological events and
formations that occured/existed throughout the whole geological
history, and this eventually gives the relative age of the earth.
While, Absolute dating involves the use of isotopes and radioactive
elements (radioactivity) and also the study and relation of
meteorites and moon rocks, which eventually gives the actual/absolute age of the earth. The meteorites and moon rocks are
believed to have formed virtually at the same time with earth and
are therefore, considered to be of the same age as earth.
Explanation:
Answer:
Absolute dating and relative dating are both methods used to determine the age of a fossil. Absolute dating gives the actual age of a fossil in years based on the amount of radioactive and stable elements in the fossil. Relative dating gives an estimate of the age of a fossil based on the location of the fossil in relation to other fossils.

Two identical pots, one black and one silver, containing exactly the same amounts of water, are heated to the same temperature,
They are left uncovered and placed in the same room. After 15 minutes the water in the black pot is significantly cooler than the
water in the silver pot. Which of these statements best explains this difference?
Answer:
Black color absorbs heat more quickly and it also emits heat at a faster rate.
Whereas silver is one of the best conductor of heat and electricity. Therefore, it absorbs heat more quickly but it does not emit heat at a faster rate.
Therefore, we can conclude that the statement black pot emits heat at a faster rate than the silver pot best explains that black pot is significantly cooler than the water in the silver pot.
Explanation:
Hope this helps :)
Final answer:
The black pot cools faster than the silver pot because black emits infrared radiation more efficiently, thereby losing heat quicker.
Explanation:
The difference in the temperature of the water in the two identical pots, one black and the other silver, after being heated and left to cool in the same room, can be explained by the properties of radiative heat transfer. Darker colors, especially black, are known to radiate heat more efficiently than lighter colors. This means that the black pot will emit more infrared radiation than the silver pot and thus cool down faster. Both pots start at the same temperature, and given identical conditions aside from color, the differing cooling rates are due to how effectively each color emits heat as radiation.

Explanation:
Two football players are squared off against each other on the gridiron. Big Bubba has a mass of 125 kgs
but he's slower than a snail, only able to run at a measly 7 m/s. Lil' Pete, on the other side of the line, is a
skinny 80 kg, but can run like a rocket at -10 m/s. Assume that these two players are running directly at
each other and then, Wham!, they collide and bounce off of each other. To nobody's surprise, Lil' Pete
gets knocked backward with a velocity of +10 m/s; however, Big Bubba is also knocked backward: what is
Big Bubba's velocity after the collision?
Answer:
-5.8 m/s
Explanation:
Given:-
- The mass of Big Bubba, mb = 125 kg
- The mass of Lil' Pete, mp = 80 kg
- The initial velocity of Big Bubba, vb = 7 m/s
- The initial velocity of Lil Pete , vp = -10 m/s
- The velocity after impact of Lil' Pete, vp' = + 10 m/s
- The velocity after impact of Big Bubba = vb'
Find:-
what is Big Bubba's velocity after the collision?
Solution:-
- We will consider the two football players as particles of mass mb and mp with their respective velocities vb and vp heading towards each other.
- The masses collide and both reverse in direction with velocities vb' and vp'.
- The system of the two masses have no external forces acting on it; hence, the system is isolated from any fictitious forces.
- For above conditions we can apply the principle of conservation of linear momentum. The linear momentum of two football players before ( Pi ) and after the impact ( Pf ) remain constant. The conservation is:
Pi = Pf
mb*vb + mp*vp = mb*vb' + mp*vp'
mb*vb + mp*( vp - vp' ) = mb*vb'
- Develop an expression for Big Bubba's velocity after impact vb':
vb' = vb + mp/mb*( vp - vp' )
- Plug in the values and evaluate:
vb' = 7 + 80/125*( -10 - 10 )
vb' = 7 - 80*20 / 125
vb' = -5.8 m/s
Answer: The velocity of Big Bubba after impact is vb' = -5.8 m/s
True or false: When an object becomes polarized, it acquires a charge and becomes a charged object.
Answer:
i think its true
Explanation:
Polarization is the non-symmetrical distribution of charges within a neutral object, and it does not mean that the object becomes charged.
The statement, "When an object becomes polarized, it acquires a charge and becomes a charged object," is false. Polarization is the separation of positive and negative charges within an inherently neutral object. For example, consider two metallic spheres that are neutral. When a charged glass rod is approached to the spheres, it induces a negative charge on the side nearest to the rod, leaving the other side of the spheres positively charged. However, the spheres as a whole remain electrically neutral. This is an instance of induced polarization.
It's also crucial to understand that charging by polarization does not require direct contact with a charged object. When the spheres are separated before the charged rod is removed, each sphere will have a net charge, which is the result of charging by induction, not by transfer of charge through contact. This process can be repeated multiple times without depleting the excess charge on the rod, emphasizing the non-contact nature of the process.
How is potential energy transformed into kinetic energy
Answer:
Potential energy is converted into kinetic energy by a force. For example, when you pick up a rock, you work against gravity to give it some potential energy. And then when you drop it, the gravitational force causes the rock to accelerate towards the ground
Explanation:
Potential energy is transformed into kinetic energy through various natural processes. An example is a rollercoaster which at the peak has high potential energy due to its height, but as it descends and increases speed, the potential energy is transformed into kinetic energy. This phenomenon is guided by the Law of Conservation of Energy.
Explanation:In physics, potential energy is stored energy that an object has due to its position or state. Kinetic energy on the other hand, is the energy that an object possesses due to its motion. The transformation between these two forms of energy occurs continuously in the natural world.
For instance, think of a rollercoaster at the peak of a track. It has a high potential energy because of its height. As the rollercoaster starts to descend, the potential energy is transformed into kinetic energy as the rollercoaster increases speed (due to gravity). When it gets to the lowest point, all of its potential energy has been converted into kinetic energy. This cycle continues for the duration of the ride, with the rollercoaster's energy constantly being transformed between potential and kinetic.
This transformation between potential and kinetic energy is referred to as the Law of Conservation of Energy, which states that energy cannot be created or destroyed, it can only be transformed from one form to another.

What is the relationship between wavelength and the amount of energy the wave carries?
Answer:
Energy is inversely proportional to wavelength.
Explanation:
The amount of energy, E, a wave carries is given as:
E = hf
where h = Planck's constant and f = frequency of the wave
Frequency and wavelength are related by the equation:
c = λf
=> f = c/λ
where λ = wavelength
Therefore, energy is:
E = hc/λ
This shows that energy is inversely proportional to wavelength. As wavelength increase, energy decreases and vice versa.
An AC source is connected to a series combination of a light bulb and a variable capacitor. If the capacitance is increased, the bulb's brightness A. Increase. B. Decreases C. Does not change.
Answer:
Increases
Explanation:
Since power P=IV
Then it means when current increases, the power increases hence brightness increases. I represent current, P is power and v is voltage.
Current of capacitor when in series connection is given by
[tex]I=2\pi fCV[/tex]
where I is current across capacitor, f is frequency, C is capacitance and v is voltage across capacitance. From this second formula, it is evident that an increase in capacitance increases the current across the capacitor. Therefore, if current increases, power also increases leading to an increase in brightness
Increasing the capacitance in a series circuit with an AC source and a light bulb generally increases the bulb's brightness because it reduces the capacitive reactance and allows more current to flow through the bulb. So, the correct option is A.
When an AC source is connected to a series combination of a light bulb and a variable capacitor, the brightness of the bulb is affected by the capacitive reactance of the circuit, which is inversely proportional to both the frequency of the AC source and the capacitance of the capacitor.
As the capacitance is increased (considering the frequency of the AC source is constant), the capacitive reactance decreases. This allows more current to flow through the bulb, which generally increases the bulb's brightness.
Since capacitors in an AC circuit cause the current to lead the voltage, an increase in capacitance will mean that the current increases while the voltage across the capacitor does not change significantly. Therefore, the energy dissipated by the light bulb in the form of light (and heat) increases.

Explanation
A wave has a speed of 30 m/s and a wavelength of 3 meters then its frequency is 10 Hz.
What is wave ?Wave is is a disturbance in a medium that carries energy as well as momentum . wave is characterized by amplitude, wavelength and phase. Amplitude is the greatest distance that the particles are vibrating. especially a sound or radio wave, moves up and down. Amplitude is a measure of loudness of a sound wave. More amplitude means more loud is the sound wave.
Wavelength is the distance between two points on the wave which are in same phase. Phase is the position of a wave at a point at time t on a waveform.
There are two types of the wave longitudinal wave and transverse wave.
Longitudinal wave : in which, vibration of the medium (particle) is parallel to propagation of the wave. Sound wave is a longitudinal wave.
Transverse wave : in which, vibration of the medium (particle) is perpendicular to propagation of the wave. Light wave is a transverse wave.
