The person with the most power is the person with the least time, namely, the person who ran up the slope.
The energy process that does NOT use heat energy to heat water is hydroelectric.
What else?

@ notty_me. Could you tell me the question? I kinda forgot it.
@sundars. The number of nucleons is the same as the nucleon number. So what was the nucleon (mass) number? It was 16 rite? So the answer is 16.

That was 136..because an alpha particle only has 2 neutrons.

For all those who say the fuse was 1A take a look a this....this is the same question with different numbers but the answer is still B....convinced now?

LOOOL! Actually, it's definitely not 1A because the hair drier needs 2A.. so that's why it's B which is a fuse of 3A

However, on our exam... the lamp needed 0.25 to light at maximum brightness... and the wire can carry up to 5A. So it was neither 0.2A, 5A, nor 10A....  because 1A is the most suitable.

But didnt they ask for THE OTHER END, that means the fuse is for the wire, so 10A was my answer
