When a 4-μf capacitor has a potential drop of 20 v across its plates, how much electric potential energy is stored in this capac
Genrish500 [490]

Thew energy stored in a capacitor of capacitance C and voltage between the plates V is

E=\frac{1}{2} CV^2.

Substituting numerical value

E=\frac{1}{2}(4*10^{-6}) (20)^2\\ E=800\; \mu J

If the moon did not rotate at the same rate that it revolved, what would happen to the gravity of the earth?
dem82 [27]

Answer:

The gravity, which is an acceleration to the center of the earth, will be the same.

Explanation:

The gravity on earth depends only on the masses and distance, between two objects. We can see it in the gravitational force equation.  

F=G\frac{m\cdot M}{r^{2}}  

Now if we put a man, with mass m, on the surface of the earth, with mass M, the distance from the center of mass and the man will be R (earth radius). Knowing that F = m*a, we can find the accelerations due to this mass M and this value will be 9.81 m/s².  

On the other hand, the moon has a gravity value and is less than the earth, because its mass, and affects the water sea due to the gravitational force between earth and moon. If the moon changes the rate of its rotate it changes probably the distance between them, let's recall they must conserve angular momentum, but the gravity won't be affected.

Therefore, the gravity, which is an acceleration to the center of the earth, will be the same.

   

I hope it helps you!

A wave has a speed of 50 m/s and a frequency of 100 Hz. Calculate its wavelength.
Allisa [31]

Answer:

1/2m or 0.5m

Explanation:

The formula to find the speed of a wave is given by:

V = frequency x wavelength

To find the wavelength, make the wavelength the subject of the formula

Therefore, wavelength = velocity ÷ frequency

Fission and fusion reactions both involve making changes to an atom's _____.
spayn [35]

Option (A) is correct. Fission and fusion reactions both involve making changes to an atom's nuclei.

Nuclear fission is a process in which a bigger nucleus breaks into two or more smaller nuclei with the liberation of large amount of energy.

Nuclear fusion is a process in which two smaller nuclei fuse together to form a bigger nucleus. A tremendous amount of energy is released during fusion.

Thus both fission and fusion involve the changes in the nuclei of atoms. Rest of the atom like the electronic configuration etc remains same.
