Answer:
force = 0.20N .F = m ×a .& a = v/t then the f = m×v/t.

Out of the following choices given, if you insert a piece of rubber between the wires, the electrons do not flow. The rubber material is an insulator. The correct answer is D.
Potential energy relative to the floor =
(mass) x (gravity) x (height off the floor) =
(2kg) x (9.8 m/s²) x (2m) =
39.2 kg-m²/sec² = <em>39.2 joules </em>
Efficiency = (Wanted) energy out ÷ energy in × 100
Energy in = 400J
Wanted Energy out = 240J
Energy cannot be used up, only transferred, so the remaining energy is most likely to be transferred into unwanted energy (loss of energy) such as heat energy.
Efficiency = 240 ÷ 400 × 100
Efficiency = 0.6 × 100
Efficiency = 60%
