A 52 g plastic ball is moving to the left at 24 m/s . how much work must be done on the ball to cause it to move to the right at 24 m/s ?
Answers
To cause the plastic ball to move to the right at 24 m/s, 499.04 J of work must be done on it.
Explanation:The work done on an object is equal to the change in its kinetic energy. In this case, the plastic ball is initially moving to the left at 24 m/s. To cause the ball to move to the right at 24 m/s, the work done on it must change its direction and increase its speed by 48 m/s (difference between -24 m/s and 24 m/s). The work done can be calculated using the formula for work: Work = Change in kinetic energy = (1/2) * mass * (final velocity^2 - initial velocity^2).
Given that the mass of the ball is 52 g (0.052 kg) and the change in velocity is 48 m/s, we can plug in these values into the formula:
Work = (1/2) * 0.052 kg * (48^2 - (-24)^2) = 499.04 J
Therefore, 499.04 J of work must be done on the ball to cause it to move to the right at 24 m/s.
Answer: The resulting answer for this is 0 Joules
Explanation: For any answer that talks about a complete 180 direction change with the same velocity, the answer will always be zero.
KE = 1/2mv1^2 - 1/2mv2^2 which leads to KE = 1/2m(v1^2-v2^2) = (1/2)(0.052kg)(24^2m/s - 24^2m/s) = 0 J

B) The gravitational pull of the Sun holds Neptune in its orbit.
C) The nuclear force acting between the Sun and Neptune holds the latter in its orbit.
D) The repulsive force of bodies outside the solar system holds Neptune in its orbit.
Answers
Answer:
B. The gravitational pull of the sun holds Neptune in its orbit.
Explanation:
Whether a farthest planet or a nearest planet, all the planets in the solar system are held in their respective orbits by the mutual gravitational force of attraction. That is, the Sun exerts a gravitational force on the planet and the planet in turn pulls the Sun towards it. These two forces are equal in magnitude and oppositely directed to each other.
That is very well explained by the Newton's universal gravitational law,
As the distance between the Sun and the planet increases, the mutual gravitational force of attraction between the planets will decrease.
Mercury, Venus, Earth , Mars, Jupiter, Saturn, Neptune and Uranus are the planets that belong to the solar system. All these planets are revolving around the Sun.

Compare and contrast the movement of electric charge in a solution with the transfer of electric charge between solid objects.
Answers
In solid objects, instead, the movement of electric charge is given by the movement of valence electrons or by holes, created when a valence electron leaves a vacancy in the outer shell of an atom.
Electric charge transfer between solid objects involves the movement of electrons, whereas in solutions it involves the movement of both cations and anions. Both processes follow the principle of charge conservation.
Understanding the movement of electric charge requires comparing how it occurs in solutions versus solid objects. In solid objects, charge transfer primarily happens through the movement of electrons. When two solid objects come into contact, electrons can be transferred from one object to another, often facilitated by friction, leading to one object becoming negatively charged and the other positively charged.
On the other hand, in a solution, electric charge is carried by ions. For instance, in an ionic solution like salt water, both positive ions (cations) and negative ions (anions) can move freely. This is different from the transfer between solid objects where only electrons, carrying negative charges, move.
The relationship between the total charges before and after the transfer is that the total amount of charge is conserved. This means the sum of positive and negative charges remains constant, even though the charges might be redistributed. This principle is crucial in both solid object charge transfer and ionic solutions.
So, while the transfer of electric charge between solid objects involves moving electrons, in a solution, it involves the movement of both cations and anions. Both processes abide by the principle of charge conservation, ensuring that the total charge remains constant.

A car starts from rest at a stop sign. It accelerates at 4.0 m/s2 for 3 seconds, coasts for 2 s, and then slows down at a rate of 3.0 m/s2 for the next stop sign. How far apart are the stop signs?
Answers
a) accelerated motion
what we know: initial velocity vi = 0, time t = 3s, acceleration a = 40m/s²;
the formula to find the space is: s = vi + 1/2·a·t²
all the units of measurement are fine,
therefore: s = 0 + 1/2·4·9 = 18m
b) constant motion
we know t = 2s and that the velocity here is equal to the final velocity (vf) of part a), which we need to calculate:
vf = vi + a·t which brings vf = 0 + 4·3 = 12m/s;
we can know calculate the total space with the formula s = vf·t = 12·2 = 24m
c) decelerated motion
we know the acceleration a = -3m/s² (minus because the velocity is decresing) and the initial velocity which is equals to the velocity of part b), therefore vi = 12m/s
we need to calculate first the time taken to bring the car to stop, we can use the formula t = v/a = 12/3 = 4s
we can know calculate the space through the formula
s = vi·t + 1/2·a·t² = 12·4 + 1/2·(-3)·(4²) = 48 - 24 = 24m
We can now sum up the three spaces found to get the total distance between the stop signs:
s = sa + sb + sc = 18+24+24 = 66m

the electron cloud model describes which of the following

location where an electron has the highest probability of being found
Answers
The electron cloud model in physics describes the location where an electron has the highest probability of being found around an atom. Option D
The older Bohr model of the atom, which showed electrons orbiting the nucleus in set pathways like to planets orbiting the sun, was superseded by this one. Instead of representing electrons as particles in fixed orbits, the electron cloud model views electrons as a cloud-like region surrounding the nucleus, with each point representing the likelihood of finding an electron there.
This idea highlights how electrons are characterized by their quantum mechanical nature, which prevents them from being localized and instead allows them to be represented by probabilities within particular spatial regions surrounding the nucleus. Therefore, the understanding of electron dispersion surrounding the nucleus of an atom depends on the electron cloud model.
The electron cloud model describes the location where an electron has the highest probability of being found within an atom.
This model, also known as the quantum mechanical model, represents electrons not as definite orbits but as regions of probability called electron clouds.
It accounts for the wave-like nature of electrons and their distribution in atomic orbitals, where electrons are most likely to be found based on their energy levels and quantum numbers.
It does not describe the group of protons in the nucleus, the neutron orbital, or the negative charge of the electron; rather, it focuses on the spatial distribution of electrons in an atom.

Michaela answered the phone when Tommy's parents called to check him leaving Timmy unattended for three minutes .During that time Tommy turned the oven on its hottest setting and placed his new police car Mylar ballon in the oven. what will most likely happen to his ballon
Answers
Explanation:
The air in the ballon will increase its temperature and, according to the laws of behavior of the gases, it will expand until it explode.
You can assume ideal gas behavior and use PV = nRT, where you can see that the volume V and P are proportional to the temperature T, so with the increase in temperature the ballon will increase its volume, until the material of the ballon can not expand more, when the pressure will increase and the material will fail.
the balloon will pop
The increased temperature will cause the particles in the balloon to move faster and will create more pressure on the balloon. This pressure will pop the balloon.

Answers
[tex]Q=2\pi f \frac{energy\ stored}{power\ loss}[/tex]
We will need to figure out power loss and energy stored.
Power loss is happening due to friction. It is equal to power that the weight is supplying to the clock:
[tex]P_l=\frac{mg\Delta h}{\Delta t}=\frac{0.2\cdot 9.81 \cdot 2}{24\cdot 60 \cdot 60}=0.000045W[/tex]
Now we need to figure out the energy stored in one the pendulum. We can think of this as potential energy of the pendulum:
[tex]E_s=m_pgh_p=m_pgL(1-cos(\theta))=0.01\cdot 9.81 \cdot 0.25 \cdot (1-\cos(0.2))[/tex]
[tex]E_s=0.0004888J[/tex]
Please see the attachment for clarification.
Now we can calculate the Q factor:

what mechanical layer lies below the lithosphere
Answers
Answer: The layer below the lithosphere lies the Asthenosphere.
Explanation:
The asthenosphere is a viscous layer, in which the rocks are solid but has the ability to slightly flow due to deformation. This layer plays a very significant role in the plate tectonic movement, which initiates the motion of the lithospheric crust, due to the generation of the convection current at the mantle. It is present in the upper part of the mantle.
The internal heat from the core of the earth radiates to the mantle, and the magma at the mantle gets heated up and become less dense and rises up, and this magma when reaches on the upper part of the mantle, near the surface, gets cools down and become more dense, and sinks. This continuous circulation of magma in the mantle region is known as the convection current.
The layer below the lithosphere is the asthenosphere, which is semi-fluid and allows the tectonic plates of the lithosphere to move.
Explanation:The mechanical layer that lies below the lithosphere is known as the asthenosphere. This semi-fluid layer is located directly underneath the rigid lithospheric plate and is characterized by its ability to flow and move. Due to intense heat and pressure coming from the earth's core, the rocks in the asthenosphere exist in a plasticky, semi-liquid state, which allows the tectonic plates of the lithosphere to move and shift above it.

Final answer:
The electric field does work on a proton when it moves between two points with a potential difference, with the value calculated as 3.204 × 10-17 joules.
Explanation:
The question asks us to calculate the work done by the electric field in moving a proton between two points with a specified electric potential difference. Since work done by an electric field is equal to the charge of the particle times the change in electric potential (W = qV), and we know the proton's charge is approximately 1.602 × 10-19 coulombs, we can calculate the work done as follows:
Change in potential (V) = Vfinal - Vinitial = (-55 V) - (+145 V) = -200 VWork done by the electric field (W) = qV = (1.602 × 10-19 C) × (-200 V) = -3.204 × 10-17 JThe negative sign indicates that the electric field is doing work on the proton in the direction opposite to the electric field. Therefore, the electric field does 3.204 × 10-17 joules of work on the proton.

A soccer ball is kicked with an initial speed of 8.8 m/s. After 0.179 s it is at its highest point. What was its initial direction of motion?,
Answers
The initial speed of the ball on the y-axis is [tex]v_0 \sin \alpha[/tex], where [tex]v_0 = 8.8 m/s[/tex] and where [tex]\alpha [/tex] is the angle of the initial velocity v0 with respect to the horizontal, so it's the direction that we want to find.
The law of the velocity on the y-axis is:
[tex]v(t)=v_0 \sin \alpha + gt[/tex]
Where t is the time. At its highest point, the vertical velocity of the ball is zero, and this occurs when t=0.179 s: [tex]v(0.179 s)=0[/tex]. So we can write:
[tex]v(0.179 s)=v_0 \sin \alpha + gt=0[/tex]
And substituting the numbers we can find the value of the angle:
[tex]\sin \alpha = \frac{-gt}{v_0}= \frac{-(-9.81 m/s^2)(0.179 s)}{8.8 m/s}=0.20 [/tex]

Suppose you were asked to demonstrate electromagnetic induction. Which of the following situations will result in an electric current?
A magnet is moving toward a wire loop.
A wire loop is moving away from a magnet.
A wire loop is rotated near a magnet.
All of the above
Answers
In fact, electromagnetic induction occurs when there is a change of the magnetic flux through the area enclosed by a circuit (in this case, the area enclosed by the wire loop).
The magnetic flux [tex]\Phi_B[/tex] through a certain surface is given by
[tex]\Phi_B=B A cos \theta[/tex] (1)
Where B is the intensity of the magnetic field, A is the area enclosed by the circuit and [tex]\theta[/tex] is the angle between the direction of the field B and the perpendicular to the area.
In the first situation, the magnet is getting closer to the loop, so the magnetic flux through the area enclosed by the wire is increasing (because the intensity of the magnetic field B is increasing). Situation 2) is the opposite case: the wire loop is moving away from the magnet, so the intensity of the magnetic field B is decreasing, and therefore the magnetic flux is decreasing as well.
Finally, in the third situation the wire loop is rotating. Here the distance between the loop and the magnet is not changing, but remember that the magnetic flux depends also on the angle between the direction of the magnetic field and the perpendicular (formula 1), and so since the wire loop is rotating, than this angle is changing, therefore the magnetic flux is changing as well.
