I think that's <span>heat engine.</span>
I hope I helped :D
Electromagnetic waves are often called "electromagnetic radiation".
That's a really strong clue.
Heat carried in the form of electromagnetic waves is radiation.
Answer:
754.6 m
Explanation:
The GPE (Gravitational potential energy) of an object with respect to the ground is given by

where
m is the mass of the object
g = 9.8 m/s^2 is the acceleration due to gravity
h is the heigth above the ground
Here we have
m = 12,400.05 kg is the mass
GPE = 91,700,000.00J is the GPE
Solving the formula for h, we find the heigth:

Answer is C. Because protons and neutrons are more massive then electrons so that means A and b and C are not right
