Hello,
The answer is B) <span>electrical to mechanical.

it has 3 electrons. brainliest please
Answer: t = 10s
Explanation:
Assuming there's no air resistance,
Initial velocity (u) = 0 m/s
Acceleration by gravity (a) = 9.81 m/s^2
Displacement (s) = 500m
Time taken (t) = ?
Now,
Use formula,
s = u×t + (1/2)×a×t^2
s = 0×t + (1/2)×9.81×t^2
500 = 4.905×t^2
t = 10s
Explanation:
To determine the amount of electrical charge that flows in a circuit, you need to know the current flow and how long it flows for. The equation is: charge (coulomb, C) = current (ampere, A) × time (second, s). For example, if a a current of 20 A flows for 40 s, the calculation is 20 × 40.
