<h3>Your answer would be C</h3>
Current<span> is a flow of electrical charge carriers, usually electrons or electron-deficient atoms. ... Physicists consider </span>current<span> to flow from relatively positive points to relatively negative points; this is called conventional </span>current<span> or Franklin </span>current. Electrons, the most common charge carriers, are negatively charged.
Voltage<span> is electric potential energy per unit charge, measured in joules per coulomb ( = volts). It is often referred to as "electric potential", which then must be distinguished from electric potential energy by noting that the "potential" is a "per-unit-charge" quantity.</span>
The electrical resistance<span> of a circuit component or device is defined as the ratio of the voltage applied to the electric current whichflows through it: If the </span>resistance<span> is constant over a considerable range of voltage, then Ohm's law, I = V/R, can be used to predict the behavior of the material.b

Answer:
The kinetic energy of the phone would increase. The gravitational potential energy of the phone would decrease.
Explanation:
The kinetic energy
of an object is proportional to the square of the speed of that object. If air resistance is negligible, the phone would accelerate under gravitational pull and speed up. Hence, the kinetic energy of the phone would increase.
The gravitational field near the surface of the earth is approximately constant. Hence, the gravitational potential energy
of the phone would be proportional to its height. As the phone approaches the ground, the height of the phone becomes lower and the gravitational potential energy of the phone would decrease.

![8.71*10^{-15}](https://tex.z-dn.net/?f=8.71%2A10%5E%7B-15%7D)
Explanation:
The rest energy is the energy associated with the base ball at zero velocity which is expressed as
![Rest energy=mc^{2}\\](https://tex.z-dn.net/?f=Rest%20energy%3Dmc%5E%7B2%7D%5C%5C)
Note: the speed C is the speed of light which is expressed as 3*10^8
while the kinetic energy is the energy associated with the ball during its motion and is expressed as
![Kinetic energy=1/2mv^{2}](https://tex.z-dn.net/?f=Kinetic%20energy%3D1%2F2mv%5E%7B2%7D)
the ratio can be expressed as
![\frac{Kinetic Energy}{Rest Energy}=\frac{\frac{1}{2}mv^{2} }{mc^{2}}\\since V=39.6m/s\\C=3*10^{8}m/s\\\frac{Kinetic Energy}{Rest Energy}=\frac{\frac{1}{2}39.6^{2} }{(3*10^8)^{2}} \\\frac{Kinetic Energy}{Rest Energy}=\frac{784.08}{9*10^{16}} \\\frac{Kinetic Energy}{Rest Energy}=8.71*10^{-15}](https://tex.z-dn.net/?f=%5Cfrac%7BKinetic%20Energy%7D%7BRest%20Energy%7D%3D%5Cfrac%7B%5Cfrac%7B1%7D%7B2%7Dmv%5E%7B2%7D%20%7D%7Bmc%5E%7B2%7D%7D%5C%5Csince%20V%3D39.6m%2Fs%5C%5CC%3D3%2A10%5E%7B8%7Dm%2Fs%5C%5C%5Cfrac%7BKinetic%20Energy%7D%7BRest%20Energy%7D%3D%5Cfrac%7B%5Cfrac%7B1%7D%7B2%7D39.6%5E%7B2%7D%20%7D%7B%283%2A10%5E8%29%5E%7B2%7D%7D%20%5C%5C%5Cfrac%7BKinetic%20Energy%7D%7BRest%20Energy%7D%3D%5Cfrac%7B784.08%7D%7B9%2A10%5E%7B16%7D%7D%20%5C%5C%5Cfrac%7BKinetic%20Energy%7D%7BRest%20Energy%7D%3D8.71%2A10%5E%7B-15%7D)
