Answer:

when two electrons are in close proximity Each atom's electron begins to detect the proton of the other atom. As a result, it is attracted to not just its own proton, but also the proton of the other atom.

The value of maximum voltage, when the capacitor can withstand a peak voltage of 670 v is 47.6 volts.

Resonance frequency is the natural frequency of an particle or object. At this frequency, the object tries to vibrate at higher amplitude. It can be calculated with the following formula:

[tex]f=\dfrac{1}{2\pi LC}[/tex]

Here, L is the induction and C is the capacitance.

Let for an L-R-C circuit, the value of resistance is 400 ohm, induction is 0.380 Haney and capacitance is 1.20×10⁻² μF.

Put the values in above formula,

[tex]f=\dfrac{1}{2\pi(0.380)(1.20\times10^{-8})}\\f=2356.8\rm\; Hz[/tex]

The capacitor can withstand a peak voltage of 670 v. Use the following formula to find the value of current as,

[tex]I=2\pi fC\times Vc\\I=2\pi (2356.8)(1.20\times10^{-8})\times 670\\I=0.119\rm\; A[/tex]

The value of resistance is 400 ohms. Thus, the voltage is,

[tex]V=IR\\V=(0.119)(400)\\V=47.6\rm\; V[/tex]

Thus, the value of maximum voltage, when the capacitor can withstand a peak voltage of 670 v is 47.6 volts.

The value of change in kinetic energy, when fish with mass 0. 65 kg is leaping to the right at 15 m/s, is 93.1 J.

Kinetic energy is a type of energy, which a body is posses due to its motion. The kinetic energy of a body can be found with the following formula,

[tex]KE=\dfrac{1}{2}mv^2[/tex]

Here, (m) is the mass of the body, and (v) is the speed of the body.

When the two objects collides, then the initial collision of the two body is equal to the final collision of two bodies by the law of conservation of momentum.

[tex]m_1u_1 + m_2u_2 = (m_1+m_2)v[/tex]

Here, (m) is the mass, (u) is initial velocity before collision, v is final velocity after collision and (subscript 1,2) are used for fish 1 and 2.

The mass of the first fish is 0. 65 kg. This fish leaping to the right at 15.0 m/s collides inelastically with another fish with mass 0.950 kg leaping to the left at 13.5 m/s. Put the values,

[tex]m_1u_1 + m_2u_2 = (m_1+m_2)v\\0.65\times15 +0.95\times(-13.5) = (0.65 + 0.95)\times v[/tex]

The value of initial velocity of the second fish is taken negative as it is leaping to the left.

[tex]0.65\times15 +0.95\times(-13.5) = (0.65 + 0.95)\times v\\v=-\dfrac{3.075}{1.6}\\v=-1.9219\rm\; m/s[/tex]

This is the final velocity. Now to find the change in kinetic energy use the formula of kinetic energy,

[tex]\Delta KE=\dfrac{1}{2}(0.65)(12-(-1.9219))^2\\\Delta KE=93.1\rm\; J[/tex]

Explanation

Dont judge me but I convert 1.3 hours to 78 minutes, then divide with 3.0 and we end up with 60C

The amount of charge that passes through a 3.0 amp television in 1.3 hours would be 14040 Coulombs.

Charged material experiences a force when it is exposed to an electromagnetic field due to the physical property of electric charge. You can have a positive or negative electric charge.

I = Q / T

As given in the problem, we have to find out what amount of charge passes through a 3.0 amp television in 1.3 hours.

Let us first convert the time period of hours into seconds

1 hour = 3600 seconds

1.3 hours = 1.3 × 3600 seconds

               =  4680 seconds

By using the above relation between electric current and electric charge

and by substituting the respective values of the charge and the time period

I = Q / T

3 = Q / 4680

Q = 3 × 4680

   = 14040 Coulombs

Thus, the amount of charge that passes through a 3.0 amp television in 1.3 hours would be 14040 Coulombs.

The amount of exhaust heat discharged per hour from the plant which produces electric energy at the rate of 1. 5 gw, is 9.36×10¹⁹ J/h.

The heat is discharged per hour is equal to the different of total power and actual power.

The plant produces electric energy at the rate of 1. 5 gw. Let assume the efficiency of this power plant is 64% between the temperature of 660 degree C to 330 degree Celsius.

Thus, the maximum efficiency is,

Answer:

A

Explanation:

The magnitude of the change in momentum of the driver is 3900kgm/s.

Hence option D) 3900 kg • meters per second is the correct answer.

Momentum is simply the product of the mass of an object and its velocity.

Its is expressed as;

P = m × v

Where m is the mass of the object and v is its velocity.

Given the data in the question;

We substitute the given values into the expression above to determine the initial momentum of the driver before he was brought to rest.

P initial = m × v

P initial = 125kg × 31m/s

P initial = 3875 kgm/s ≈ 3900kgm/s

Now, as the driver is brought to rest, final velocity becomes zero

P final = 125kg × 0

P final = 0

This means that the change in momentum of the driver is his initial momentum which is 3900kgm/s.

Therefore, the magnitude of the change in momentum of the driver is 3900kgm/s.

Hence option D) 3900 kg • meters per second is the correct answer.

Answer:

The pressure of the gas will increase

Explanation:

When gas is put into a container, for example, a balloon, the gas expands to fill the space it can occupy. Since gas is not a solid or a liquid, its particles are all over the place - they are constantly moving and vibrating. As such, when too much gas is blown into a balloon, it will pop. So, when the volume of the container decreases, the pressure of the gas will increase the smaller it gets. Vice versa, the greater the space, the less pressure that will be present in the container.
