What is the relationship between the angle of incidence and the angle of refraction when light passes from a medium where its sp

eed is greater into a medium where its speed is lower?

Bogdan [553]2 years ago

Answer:

This is because the speed of a wave is determined by the medium through which it is passing. When light speeds up as it passes from one material to another, the angle of refraction is bigger than the angle of incidence. For example, this happens when light passes from water to air or from glass to water ❤

A 400-kg object has a 100-Newton rightward net force being applied to it. What is the magnitude of the rightward acceleration on
aliya0001 [1]

Answer:

The answer to your question is a = 0.25 m/s²

Explanation:

Data

mass = m = 400 kg

Force = F = 100 N

acceleration = a = ? m/s²

Process

To solve this problem use Newton's second law that states that the force applied to an object is directly proportional to the mass of the body times its acceleration.

Formula

                       F = ma

solve for a

                       a = \frac{F}{m}

Substitution

                       a = \frac{100}{400}

Simplification and result

                              a = 0.25 m/s²

Earth’s atmosphere is in hydrostatic equilibrium. What this means is that the pressure at any point in the atmosphere must be hi
Misha Larkins [42]

Answer: The pressure that one experiences on the Mount Everest will be different from the one, in a classroom. It is because pressure and height are inversely proportional to each other. This means that as we move up, the height keeps on increasing but the pressure will keep on decreasing. This is the case that will be observed when one stands on the Mount Everest as the pressure is comparatively much lower there.

It is because as we move up, the amount of air molecules keeps on decreasing but all of the air molecules are concentrated on the lower part of the atmosphere or on the earth's surface.

Thus a person in a low altitude inside a classroom will experience high pressure and a person standing on the Mount Everest will experience low pressure.

What will happen to plant height if the amount of available light is reduced due to global dimming? Which type of investigation
Lorico [155]
The plant will not grow. In fact it could have all the nutrients and all the water it needs, but without a sufficient amount of light, it could die because its leaves are meant for a certain minimum amount of light.

I'll come back and see if you have posted the question you wanted and edit my answer.

Prove the correctness of this equation s=vt + 1/2at ​
Kaylis [27]

Answer:

The formula is dimensionally correct.

Explanation:

Given

s = ut + \frac{1}{2}at^2

Required

Prove its correctness

Write out the dimension of each:

s = M^0LT^0 --- displacement

ut = M^0LT^{-1} *  T --- velocity * time

\frac{1}{2}at^2 = M^0LT^{-2} * T^2 --- acceleration * square of time

The expression becomes:

s = ut + \frac{1}{2}at^2

M^0LT^0 = M^0LT^{-1} *  T + M^0LT^{-2} * T^2

Apply law of indices

M^0LT^0 = M^0LT^{-1+1} + M^0LT^{-2+2}

M^0LT^0 = M^0LT^{0} + M^0LT^{0}

M^0LT^0 = M^0LT^{0}

Both sides of the equation are equal
