Because thats the motor working hard to process food
A. Conductors. Because in conductors, gap between valence band and conduction band is negligible. Due to this electrons from valence band moves spontaneously to conduction band and on small heating the conductors.
I have no idea what that is, but all of your answers right
The maximum efficiency is 10%
Explanation:
The maximum efficiency of a machine is given by:

where
is the temperature of the hot reservoir
is the temperature of the cold reservoir
For the machine in this problem, we have:
is the temperature of the hot reservoir
is the temperature of the cold reservoir
substituting, we find the max efficiency:

So, the efficiency is 0.10 (10%).

Answer:
I guess the answer is
-The mass and volume of an object determine if it will sink or float
Explanation:
An object that has a higher density than the liquid it's in will sink. An object that has a lower density than the liquid it's in will float.
density=mass/volume
