First law of thermodynamics
Explanation:
The statement that energy can that "energy can neither be created nor destroyed but changed or transformed from one form to another" is the first law of thermodynamics.
- Thermodynamics deals with energy changes that accompanies a process.
- we can deduce from the first law that energy is conserved in every system.
- Energy is simply not produced by converted from one form to another in nature.
- For example, the heat energy we derive from eating food is due to the chemical energy stored in them.
- The chemical energy is converted into heat energy during digestion.

A machine can never be 100% efficient because some work is always lost
due to the lack of materials or equipment that would convert work by 100%. It follows
the second law of entropy. The ideal engine is known as Carnot’s engine having
a 100% efficiency. So far, no engine has ever gotten to 100%.
Answer:
Explanation:
<u>Dynamics</u>
When a particle of mass m is subject to a net force F, it moves at an acceleration given by
The particle has a mass of m=2.37 Kg and the force is horizontal with a variable magnitude given by
The variable acceleration is calculated by:
The instant velocity is the integral of the acceleration:
Integrating
Answer:
A microwave
Explanation
The human retina can only detect incident light that falls in waves 400 to 720 nanometers long, so we can't see microwave or ultraviolet wavelengths. This also applies to infrared lights which has wavelengths longer than visible and shorter than microwaves, thus being invisible to the human eye.
