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

What does the universal law of gravitation state

kodGreya [7K]

Every mass is attracted to every other mass with a force that is proportional
to the product of both masses and inversely proportional to the square of the
distance between their centers of mass. The forces act along the line between
their centers of mass.

A sports car and a minivan run out of gas and are pushed to the side of the road. Which is easier to push, and why?

astraxan [27]

Answer:

The correct option is;

The sports car, because it has less mass and therefore less inertia

Explanation:

Newton's first law of motion states that an object will continue in its state of rest or uniform motion in a straight line unless acted on by a force. The property exhibited by the object is known as inertia

Newton's second law states that force is directly proportional to the rate of change of momentum produced

The rate of change of momentum of an object is directly proportional to the resultant force applied and is in the direction of the resultant force. The resultant force is equal to the rate of change of momentum.

Therefore, we have;

F = m·dv/dt = m×a

Given that the force required to move an object is directly proportional to its mass therefore, the inertia or the object resistance that requires a force to bring change is directly proportional to the mass of the object.

The mass of a sports car being considered lesser than the mass of the minivan will require less force to push and therefore has less inertia.
