Answer:
Heat flow is the movement of heat.
Explanation:
Heat flows in solids by conduction, which occurs when two objects in contact with each other transfer heat between them. That happens because the molecules hit each other, and the faster moving molecules in the hot object spread that energy into the cooler object

Answer:
a) 390J
b) 322J
c) 68J
Explanation:
We need to calculate the power given by the battery. the power is given by:
Watts is J/s so:
The thermal energy in the wire is given by:
And the the dissipated thermal energy in the battery will be the remainig energy:
<span> All of the choices were physicists, bu</span>t the answer was Ampere. The discovery that one current-carrying wire exerts a force on a second current-carrying wire was made by Andre-Marie Ampere.
Answer:
4N downward
Explanation:
the 16N left and right cancel each other out, so you are left with the 4N downward.
