The process by which the heat energy is transmitted between the atoms or molecules is known as conduction.

Explanation:

Conduction is the transfer of heat through the material that are caused by temperature gradient with the material ends in heat flux. The heat transfer done by movement and mixing of a fluid is known as convection.

If a fluid is taken and it is kept as stationary. If there is a temperature gradient across that fluid, there would be transfer of heat that occurs in the fluid. It is negligible when compared to convective heat transfer.

Because of the heat transfer from solid to solid, density of liquid changes and start to move in upward direction due to low density. This type of motion is known as convection currents.

An object experiences an acceleration of -6.8m/s^2. As a result, it accelerates from 54m/s to a complete stop. how much distance
Kipish [7]

Answer:

210 m

Explanation:

Given:

a = -6.8 m/s²

v₀ = 54 m/s

v = 0 m/s

Find: Δx

v² = v₀² + 2aΔx

(0 m/s)² = (54 m/s)² + 2 (-6.8 m/s²) Δx

Δx ≈ 210 m

What is the relationship between refraction and the speed of light?
tankabanditka [31]

Answer:

n=\frac{c}{v}

Explanation:

Refraction: It is a process in which light ray travel from one medium to another medium.

When a light  travel form one medium to another medium then the speed of light changes.

When a light travel from rare to denser  medium then the light bend towards normal .

When a light travel form denser to rare medium then the light ray bend away from the normal.

Refractive index:It is a ratio of velocity of light in vacuum to the velocity of light in medium .It is a measure of change in speed of light when it passes from vacuum into material.It is represented by "n''.

Mathematical representation:

n=\frac{c}{v}

Where n=Refractive index of material

c=Velocity of light in vacuum

v=Velocity of light in medium
