If Light is travels from air into pure water with an incident angle of 30°. What is the angle of refraction?
Orlov [11]

Explanation:

For air, n1 = 1.00003; for water, n2 = 1.3330

Given: θ2 = 30 degrees, then

θ1 = arcsin [(n2/n1) sin θ2]

= arcsin [(1.3330/1.0003) sin (40)]

= 58.93 degrees

Note that since, in this example, light is traveling from a medium of higher density (water; n2 = 1.3330) to a medium of lower density (air; n1 = 1.0003), then n2 > n1, and the angle of refraction (θ1) is larger than the angle of incidence (θ2), thus the light bends away from the normal (in this example, the vertical) as it leaves the water and enters the air.

If you exert a force on an object in motion you will change its ____.
devlian [24]

If you exert a force on an object in motion, then depending on the
direction of the force you exert and the direction in which it's already
moving, you may speed it up, slow it down, or change the direction
of its motion. Any of these changes is called an acceleration. 

In addition to that, you'll change the object's momentum and kinetic energy.
They may increase or decrease ... again depending on the directions of the
motion and the new force.

You will not change the object's mass, inertia, weight, color, cost,
political affiliation, or gender preference.

The moon remains in Earth's orbit because of Earth's gravitational pull on the moon. In return, the moon exerts a gravitational
Vladimir [108]

Given what we know, we can confirm that the Earth pulls more strongly on the moon, option A is correct.

<h3 /><h3>Why does the Earth pull more strongly?</h3>

This has to do with the relationship between the mass of an object and its gravitational pull. These values are <u>directly proportional</u>, the more massive an object is, the stronger the gravitational pull that object exhibits. The moon does pull on the Earth as well, however, due to its smaller mass, it does not pull as strongly as the Earth on the moon.

Therefore, we can confirm that the Earth pulls more strongly on the moon, which means that option A is the correct choice for this question.
