All parts of the body (muscles, brain, heart, and liver) need energy to work. This energy comes from the food we eat. Our bodies digest the food we eat by mixing it with fluids (acids and enzymes) in the stomach.
Answer:
(a) Energy density will be equal to 
(b) Total energy will be equal to 0.0718 J
Explanation:

Answer:
Visible waves can be seen by people.
Explanation:
Electromagnetic waves comprises of different kind of waves. It consists of cosmic waves, x-rays waves, gamma waves, ultra violet waves, visible waves, infrared waves, microwaves. Among these waves, depending upon the wavelength of each kind of waves, it is visible and invisible to naked eyes. Thus, visible waves are the one which can be seen by people in naked eyes. As the wavelength of these waves are in comparable to the eye sight, so it can be seen by people.
The correct answer is A. Solid
Gas has the least density because the atoms and molecules spread to fit the container. Liquids is between solid and gas when it comes to density, while solid has the highest density due to the way the molecules are tightly and closely connected.
