Answer:
The ray's angle with respect to the face of the crystal is 71.6°
Explanation:
Given that,
Incidence angle = 27°
We need to calculate the angle of refraction
Using Snell's law
Put the value into the formula
We need to calculate the ray's angle with respect to the face of the crystal
Using formula of refraction
Put the value into the formula
Hence, The ray's angle with respect to the face of the crystal is 71.6°
Answer:
Explanation:
The answer is neutrons and protons. The proton for example is composed of 3 quarks with charges of 2/3 + 2/3 - 1/3 which gives an overall charge of 1.
Neutron are composed of 2 quarks that are - 1/3 in charge and 1 that has a charge of 2/3. The overall charge is 0.

Explanation:
Energy is the most important ingredient for life. Organisms use energy in diverse ways. Scientifically, energy is defined as the ability to do work. Without this ability, organisms would not exist.
So, the most important process is one that can furnish the body with energy.
- The respiratory system happens to be the one that furnishes the body with energy.
- During respiration, the energy needs of the body is met by series of processes.
- Oxygen is taken in and use to liberate calories from chemical substances packed with energy.
- So, without respiration, the bodily energy demands will not be met.
