Answer:

A) Ratio of the speed of light in a vacuum to the speed of light in a medium (refractive index)

B) Rule for how light is refracted at the boundary between two materials (snell's law)

C) Process that occurs when the angle of incidence is greater than the critical angle (total internal reflection)

D) Path of a particle of light (ray)

E) The separation of light into different frequencies to produce a rainbow (dispersion)

The earth's radius is 6.37×10^6m; it rotates once every 24 hours. with the angular speed of 7.3 x 10^-5 what is the speed of a p
alexira [117]
The speed of the earth's surface located at 2/3 of the length of the arc between the pole which measure from the equator is 232.5 m/s.

Solution:
So the givens are, earth's radius = 6.37X10^6m, and the angular distance from the pole is 90 degrees. So 60 degrees is the 2/3.

r = 6.37x10^6 * cos(60) = 3.185x10^6m
since v = wr
v = 7.3x10^-5 * 3.185x10^6

v - 232.5 m/s

Question 1
kakasveta [241]

Answer:

W = 600 J

Explanation:

We have,

According to attached figure,

Height of the inclined plane is 60 m

Force acting on the block is 10 N

It is required to find the work must be done against gravity to move it to the top of the incline. The work done is given by :

W = mgh

or

W=F\times h\\\\W=10\times 60\\\\W=600\ J

So, the work done against the gravity is 600 J.

A plant cell is no longer capable of capturing energy from sunlight and converting it into chemical energy. Which organelle is m
Nadya [2.5K]

The chloroplast of the cell is most likely damaged if the plant cell is no longer capable of capturing energy from sunlight and converting it into chemical energy.

The chloroplast is the structure inside the leaf cell that is known for capturing light energy from the sun.

This light energy is then used to make food that has chemical energy. If a plant cell has a damaged chloroplast or the chloroplast is removed, then it will no longer be able to trap the light energy. As a result, the process of photosynthesis will not occur in the plant cell. The plant cell will not be able to make the chemical energy required for functioning.

How do mechanical waves to travel from one place to another?​
AnnZ [28]

Answer:

Mechanical waves require a medium in order to transport their energy from one location to another.

Sound waves are incapable of traveling through a vacuum. Slinky waves, water waves, stadium waves, and jump rope waves are other examples of mechanical waves; each requires some medium in order to exist.
