Answer:
mass of the planet and its distance from other objects
Explanation:
mass of the planet and its distance from other objects determine the strength of its gravitational force on other objects
For the total internal reflection of a substance, we can express the relationship between the critical angle,
, and the indices of refraction as
(1) <span>
</span>
where
and
are the indices of refraction. And under polarization, we can express Snell's Law as
Rearranging this we have
(2)Substituting equations (1) into (2), we have
Substituting the value of the critical angle, we have
Answer: 33.79°
Answer:
Potential energy
Explanation:
Potential energy is stored energy and the energy of position––gravitational energy. There are several forms of potential energy. Electrical Energy is the movement of electrical charges. Everything is made of tiny particles called atoms.

A 135-dB is 60-dB louder that 75-dB.
The question says "how much louder" so for these kinds of questions you subtract.
good luck!
Answer: Radio waves are transmitted easily through air. They do not cause damage if absorbed by the human body, and they can be reflected and refracted to change their direction. These properties make them ideal for communications.
