B) gravitational to kinetic
Explanation:
The skydiver, when he is located at a certain height h above the ground, possesses gravitational potential energy, equal to:
where m is the mass of the skydiver, g is the gravitational acceleration and h is the height above the ground. As he falls, its height h decreases, while his speed v increases, so part of the gravitational potential energy is converted into kinetic energy, which is given by
so, we see that as v increases, the kinetic energy increases. Therefore the correct answer is
B) gravitational to kinetic
there many things you could do, one is try getting a cooling system, another thing is its extramly hot and you may need to tunr off your car to prevent the engine from over heating.
Answer is A switch or a fuse in an electrical circuit is always connected to the live wire so that the socket or appliance is not live when switched off.

We need to calculate the frequency
Using formula of frequency
Where, E =energy
Hence, The frequency of this photon is
Explanation:
The given data is as follows.
= 0.25 m, q = 5.90 mC = 
= 0.35 m, q = 1.70 mC = 
(a) Now, we will calculate the electric potential as follows.
V = 
First, we will calculate the initial and final electric potential as follows.
= 
or, = 
= 
or, = 
Hence, the value of change in electric potential is as follows.
= 
= 
V
Therefore, the difference in electric potential energy is V.
(b) Now, we will calculate the potential energy as follows.
P.E = qV
= 
V
= 
Therefore, the change in the system's electric potential energy is .
