Answer:
A
Explanation:
Contact force A contact force is any force that requires contact to occur. ... Contact forces are often decomposed into orthogonal components, one perpendicular to the surface (s) in contact called the normal force, and one parallel to the surface (s) in contact, called the friction force. In the Standard Model of modern physics, the four fundamental forces of nature are known to be non-contact forces.
<span>Nuclear energy is cleaner while generating electricity. Nuclear fission provides energy without releasing greenhouse gases such as carbon dioxide. However, nuclear power plants generate significant amounts of radioactive waste. That is why we should not choose nuclear energy over fossil fuel power plants.</span>
Answer:
Explanation:
An adiabatic process refers to one where there is no exchange of heat.
The equation of state of an adiabatic process is given by,
where,
= pressure
= volume
= constant
Therefore, work done by the gas during expansion is,
(using )
