Laws of Refraction:
There are two laws of refraction.
The incident ray, the refracted ray and the normal to the surface of the point of incidence all lie at the similar plane.
The ratio of sine of angle of incidence to the sine of angle of refraction is constant for all rays passing from single medium to another medium. This constant is known as refractive index.

Does the force constant of a spring changes if it is cut into parts?
a pendulum is timed ,first for 20 swings and then for 50 swings ; time for 20 swings = 17.4 sec and time for 50 sec = 43.2. calculate the average time per swing/
formula for time period of oscillation of magnet in a vibration magnetometer
Because force=dp/dt and force=0 in first law of motion => dp/dt=0 => p=const. or linear momentum is conserved.
What is motion
