Answer:
5 I think will be none of the above and 6 could be all of the above
Making a wire thicker has the same effect as making a road wider. It makes it easier for the electron traffic to flow. The resistance decreases, and the current (traffic) increases.
Potential energy is highest at the top of the loop, and kinetic energy is highest at the bottom of the loop.
Answer:

Explanation:
Given: The latent heat of fusion for Aluminum is 
mass to be malted m = 0.75 Kg
Energy require to melt E = mL

Therefore, energy required to melt 0.75 Kg aluminum

I believe it’s B. Electrons
