How much time does it take to use 300 W of power to do 1800 J of work? Round your answer to the nearest whole number. The time is s.

Answers

Energy = power × time
1800 = 300 × time
time = 1800 ÷ 300 = 6 s

Hope it helped!

Answer:

It takes 6 seconds

Explanation:

Power is the rate of doing work. Power used or dissipated can be calculated as the relationship between the work done and the time it took to do it. That's why its units are also J/s.

Mathematically:

[tex]Power=\frac{Work}{time}[/tex]

In this case, we know about the Power and the work done, so we can calculate the time it took. Solving for time:

[tex]time=\frac{Work}{Power}[/tex]

Plugging in the values:

[tex]time=\frac{1800J}{300J/s}\\time=6s[/tex]

B. 1.6 T

In the same magnetic field, particle q₂ has a charge of 42.0 μC and a velocity of 1.21 × 10³ m/s. What is the magnitude of the magnetic force exerted on particle 2?
A. 0.042 N
B. 0.12 N
C. 0.14 N

Answers

The intensity of the magnetic force F experienced by a charge q moving with speed v in a magnetic field of intensity B is equal to
[tex]F=qvB \sin \theta[/tex]
where [tex]\theta[/tex] is the angle between the directions of v and B.

1) Re-arranging the previous formula, we can calculate the value of the magnetic field intensity. The charge is [tex]q=2.7 \mu C=2.7 \cdot 10^{-6}C[/tex]. In this case, v and B are perpendicular, so [tex]\theta=90^{\circ}[/tex], therefore we have:
[tex]B= \frac{F}{qv \sin \theta} = \frac{5.75 \cdot 10^{-3}N}{(2.7 \cdot 10^{-6}C)(773m/s)\sin 90^{\circ}}=2.8 T [/tex]

2) In this second case, the angle between v and B is [tex]\theta=55^{\circ}[/tex]. The charge is now [tex]q=42.0 \mu C=42.0 \cdot 10^{-6}C[/tex], and the magnetic field is the one we found in the previous part, B=2.8 T, so we can find the intensity of the force experienced by this second charge:
[tex]F=qvB \sin \theta=(42\cdot 10^{-6}C)(1.21 \cdot 10^3 m/s)(2.8 T)(\sin 55^{\circ})=0.12 N[/tex]

What property of a wave increases as the wave's energy increases? question 19 options: pitch frequency amplitude wavelength?

Answers

The wavelength is the length that it takes a wave to complete one cycle (measured between any two peaks or troughs that are next to each other).

More energetic light has a SHORTER wavelength, so that's not what we want.

But frequency is a measure of how long it takes for a wave to complete one cycle, or how many wavelengths pass in a certain time. We usually use one second, so the unit is [tex]s^{-1}=Hz[/tex].

Logically, shorter wavelength means that more waves pass in a second. (We deduce that frequency and wavelength are inversely proportional.)

So, more energy = shorter wavelength = greater frequency, so the answer is B.

Answers

Mass of the object m = 6.90 × 10^−9 kg Charge of the object Q = 8.30 × 10^−9 C Surface charge density = 5.90 x 10^-8 C/m^2 Distance d1 = 0.530 m, d2 = 0.170 m Kinetic energy KE = 1/2 mv^2 Work = F x d = electric field x q x d => E x 8.30 × 10^−9 x (0.530 - 0.170) Following the energy conversion principles, 1/2 x 6.90 × 10^−9 x v^2 = E x 8.30 × 10^−9 x (0.530 - 0.170) 3.45 x v^2 = 8.30 x 0.36 x E => 3.45v^2 = 3E calculating the electric field E = 5.90 x 10^-8 / ( 2 x 8.85 x 10^-12) = 3333 So 3.45v^2 = 3 x 3333 => v^2 = 9999 / 3.45 => v^2 = 2898 => v = 53.8 m/s Intial speed v = 53.8 m/s

A wagon is accelerating down a hill. Which of the following statements are true?

A. As the wagon approaches the bottom of the hill, the potential energy decreases and the kinetic energy increases.

B. The kinetic energy decreases as the wagon comes towards the bottom of the hill.

C. As the wagon approaches the bottom of the hill, the potential energy and the kinetic energy both increase.

D. The thermal energy decreases as the wagon comes towards the bottom of the hill.,

Answers

A. As the wagon approaches the bottom of the hill, the potential energy decreases and the kinetic energy increases. Potential energy and kinetic energy are opposites. At the top of the hill the wagon has max potential energy and no kinetic energy. At the bottom of the hill the wagon has max kinetic energy and no potential energy. So as the wagon approaches the bottom of the hill potential energy decreases and kinetic energy increases.

Answer:

As the wagon approaches the bottom of the hill, the potential energy decreases and the kinetic energy increases.

Explanation:

There are two types of energy possessed in the wagon i.e. potential energy and the kinetic energy. As a wagon is accelerating down a hill, its potential energy decreases and the kinetic energy increases.

We know that the energy possessed due to its height above ground level is called its potential energy while the energy possessed due to its motion is called its kinetic energy.

So, the correct option is (A) " As the wagon approaches the bottom of the hill, the potential energy decreases and the kinetic energy increases".

5. __________ is a force acting through distance.
A.Power
B.Work
C.Friction
D.Acceleration

I think it's D

Answers

B. Work. Work is a force through a distance. The equation for work is W = F x d, where F is force and d is distance. Its units are kgxm^2/s^2. The SI unit for work is joule. Acceleration is not correct. Acceleration is how quickly the velocity changes and is not a force on its own.

The correct answer to the given question is 'B. Work,' which is the force acting through a distance, as represented by the equation W = Fd.

The answer to the question, "__________ is a force acting through distance," is 'B. Work.' When a force causes an object to move through a distance, work is done on the object. The equation for work is W = Fd, where W is work, d is the distance over which the force acts, and F is the force parallel to the direction of motion. It's important to understand that acceleration (D) is the rate of change of velocity and, while it is related to force by Newton's second law (F = ma), it is not work itself. Therefore, A. Power, C. Friction, and D. Acceleration are not the correct answers in this context.

In 1990 walter arfeuille of belgium lifted a 281.5-kg object through a distance of 17.1 cm using only his teeth. (a) how much work was done on the object by arfeuille in this lift, assuming the object was lifted at constant velocity?

Answers

For the law of conservation of energy, the work done by the teeth must be equal to the variation of mechanical energy of the object. However, there is no variation of the kinetic energy K of the object, because the velocity is constant, and so K is constant as well. So the work done is simply equal to the gravitational potential energy acquired by the object, which is equal to:
[tex]U=mg\Delta h[/tex]
where m=281.5 kg is the mass of the object, [tex]g=9.81 m/s^2[/tex] is the gravitational acceleration and [tex]\Delta h=17.1 cm=0.171 m[/tex] is the height at which the object has been lifted. Using these data, we find:
[tex]U=(281.5 kg)(9.81 m/s^2)(0.171 m)=472.2 J[/tex]
And as we said above, this coincides with the work done by the teeth.

Final answer:

To calculate the amount of work done on an object, we use the formula Work = Force x Distance. In this case, the force exerted by Walter was equal to the weight of the object due to gravity, and the distance was 17.1 cm. Using these values, we find that Walter did approximately 471.3 Joules of work.

Explanation:

The question is asking about the amount of work Walter Arfeuille did when lifting a 281.5-kg object using only his teeth. In physics, the formula to calculate work is given by Work = Force x Distance. Considering that the force of gravity on the object can be calculated using the formula Force = mass x gravity, in this case, Force = 281.5 kg x 9.8 m/s² = 2756.7 N. This is the force that Walter has to exert to lift the object against gravity. Next, we convert the distance of 17.1 cm to meters to get 0.171 m. Using the work formula, we get Work = 2756.7 N x 0.171 m = 471.2957 Joules approximately. So, Walter Arfeuille did approximately 471.3 Joules of work to lift the object.

In a series circuit, the total effective resistance is
the sum of the individual resistors, and the current

If pone resistor is replaced with a resistor of lower resistance,
then the sum of the individuals is less, and the current in the

Answers

The Ideal Gas Law makes a few assumptions from the Kinetic-Molecular Theory. These assumptions make our work much easier but aren't true under all conditions. The assumptions are,

1) Particles of a gas have virtually no volume and are like single points.
2) Particles exhibit no attractions or repulsions between them.
3) Particles are in continuous, random motion.
4) Collisions between particles are elastic, meaning basically that when they collide, they don't lose any energy.
5) The average kinetic energy is the same for all gasses at a given temperature, regardless of the identity of the gas.

It's generally true that gasses are mostly empty space and their particles occupy very little volume. Gasses are usually far enough apart that they exhibit very little attractive or repulsive forces. When energetic, the gas particles are also in fairly continuous motion, and without other forces, the motion is basically random. Collisions absorb very little energy, and the average KE is pretty close.

Most of these assumptions are dependent on having gas particles very spread apart. When is that true? Think about the other gas laws to remember what properties are related to volume.

A gas with a low pressure and a high temperature will be spread out and therefore exhibit ideal properties.

So, in analyzing the four choices given, we look for low P and high T.

A is at absolute zero, which is pretty much impossible, and definitely does not describe a gas. We rule this out immediately.

B and D are at the same temperature (273 K, or 0 °C), but C is at 100 K, or -173 K. This is very cold, so we rule that out.

We move on to comparing the pressures of B and D. Remember, a low pressure means the particles are more spread out. B has P = 1 Pa, but D has 100 kPa. We need the same units to confirm. Based on our metric prefixes, we know that kPa is kilopascals, and is thus 1000 pascals. So, the pressure of D is five orders of magnitude greater! Thus, the answer is B.

How does fission and fusion affect an atoms nucleus differently?
Answer in complete sentences and include hypothetical examples.

Answers

When a heavy nucleus breaks up into two or more fragments with the liberation of energy, the process is called fission.

When two light nuclei fuse together to form a comparatively heavy nucleus, the process is called fusion. Both processes are accompanied by release of energy.

The most common example of fission is the fission of Uranium nucleus, which absorbs a slow neutron and breaks into Barium, Krypton, a few neutrons and energy.

U(235)+neutron→Ba(139)+Kr(94)+3 neutrons+200 MeV

Each fission releases around 200 MeV of energy.

The fusion reaction is responsible for energy generated by stars.

Protons in the stars combine to form a Helium nucleus with the liberation of energy.

4 protons→Helium+2 positrons+ nuetirnos+ 26.7 MeV

Fusion reactions can happen only at very high temperatures, which is required ,so that the protons have enough kinetic energy to overcome their mutual electrostatic repulsion. The temperatures that can result in fusion are of the order 10^8 K is present in stars , hence stars generate energy by fusion.

However, such temperatures are difficult to maintain and control on Earth, and hence controlled fusion reaction is still not available commercially. Experiments are on , using large magnetic fields to contain the ions that undergo fusion, since no container can hold the nuclei while they undergo fusion.

Fusion is also called clean energy, since the byproducts of fusion are not radioactive, but many fission byproducts are generally radioactive.
