Unpolarized light is incident upon two polarization filters that do not have their transmission axes aligned. if 21% of the light passes through, what is the measure of the angle between the transmission axes of the filters?

49.6°

Explanation:

= Unpolarized light

= Light after passing though second filter =

Polarized light passing through first filter

Polarized light passing through second filter

The angle between the two filters is 49.6°

when earth is in rotational motion around the sun,it displaces from its place.

when a ball is placed on an inclined surface it does both the rotational and circular motion.

explanation:

we need to know the time interval during which the force acts. impulse of force = momentum change
