Answer: D
Height of marble from ground
Explanation:
From the formula of kinetic energy and potential energy,
K.E = 1/2mv^2
While
P.E = mgh
From all the parameters given from the question. You can see that mass is constant, acceleration due to gravity is also constant.
Independent variable must be a value that can varies.
Since Jack rolled a marble down a ramp and recorded the potential energy and kinetic energy of the marble at different positions on the ramp to see the effects on both energies.
This different position must be the height which will produce an effect on the potential and kinetic energy of the marble.
Independent variable always provides an effect for dependent variable. Which are kinetic energy and potential energy in this case.
Height of marble from ground is the right answer.

Explanation:
<u><em>Electrons</em></u> are negatively charged particles that revolve around the nucleus of an atom. In QFT(Quantum field theory) Electrons are vibration of space in the positive energy field.
<u><em>Protons </em></u> are positively charged particles found in the nucleus of an atom held by the strong nuclear force. In QFT(Quantum field theory) protons are also different type of vibration in space in the direction of positive energy field.
