Question

Consider a bicycle that has a miniature generator that is turned by one of the bicycle's wheels. The generator is connected to a headlight. For each part, choose one answer only. (a) When the headlight is off, the generator transfers energy from the light to the bike transfers no energy between the light and the bike transfers energy from the bike to the light could be any of these (b) When the headlight is on, the generator transfers energy from the light to the bike transfers no energy between the light and the bike transfers energy from the bike to the light could be any of these (c) Suppose the bicycle is coasting (the rider is not pedaling) along level ground. If the rider turns on the headlight, the bicycle will not coast as far. coast farther. coast the same distance as it would have with the light off. could be any of these

Explanation / Answer

Here ,

a) when the light is off ,

as the circuit is not complete for the bulb

hence ,

no energy between the light and the bike transfers energy from the bike to the light

b)

when the headlight is on

as the circuit is complete , the bulb will glow

transfers energy from the bike to the light

c)

as the energy for lighting the bulb is taken from the bike ,

hence ,

it will not coast as far
