Answer:
D. 2.5 V
Explanation:
Electric potential of a point in space is a scalar magnitude that allows a measurement of the electric field at that point to be obtained through the electrostatic potential energy that a electric charge would acquire if it is placed at that point.
To solve this exercise it is necessary to apply the concepts related to the Snells law.
The law defines that,

Incident index
Refracted index
= Incident angle
Refracted angle
Our values are given by


Refractory angle generated when light passes through the fiber.
Replacing we have,




Now for the calculation of the maximum angle we will subtract the minimum value previously found at the angle of 90 degrees which is the maximum. Then,

Therefore the critical angle for the light ray to remain insider the fiber is 28.6°
Answer:
pretty sure its A

please give brainliest if i'm correct
Answer:
The answer is C ..
EXPLANATION:-
The amount of energy transferred between objects as a result of a difference in temperature.
Answer:
1) Coal is a natural resource, so is wood, wind energy, soil, salt, fluorite, water, and copper
2) Solar energy, natural gas, and wind energy are all renewable
3) Salt is non - renewable as is synthetic diamonds and plastic
4) I think it would be number
5) Based on their mineral, chemical, and textural composition
