It's true IF ' m ' stands for mass and ' v ' stands for acceleration. Otherwise it's false.
Answer: A heat engine uses temperature differences which cause pressure changes to exert force on a moving part. A Carnot Process is a theoretical explanation of a process involving pressure and temperature changes during ,amongst other things, phase changes.
Explanation:
Electromagnetic Waves:
Radio waves, television waves, and microwaves.
Answer:
2.11eV
Explanation:
We know that speed of light is it's wavelength times frequency.

Planck's constant is 
The energy gap is calculated by multyplying the light's frequency by planck's constant:

Hence, the energy gap is 2.11eV
Hello There!
It is Spring potential energy. Also called Elastic potential energy.
Hope This Helps You!
