Answer:
true
Explanation:
I'm assuming this is a true or false question. if u get the same results after each repeated trial that is the only time a hypothesis can be used to support evidence
Efficiency = Work Output / Work Input
92% = Work Output / 100
0.92 = Work Output / 100
Work Output = 0.92 * 100
Work Output = 92 joules.
Work = force x distance
= 100N (force) x 0.5m (distance)
= 50J
I think the answer would be 1 watt but i'm not sure
