Answer:
A Polarizing sheet transmits only the component of light polarized along a particular direction and absorbs the component perpendicular to that direction.
Consider a light beam in the z direction incident on a Polaroid which has its transmission axis in the y direction. On the average, half of the incident light has its polarization axis in the y direction and half in the x direction. Thus half the intensity is transmitted,and the transmitted light is linearly polarized in the y direction.
Oscillating Universe Theory is a cosmological model that combines both the Big Bang and the Big Crunch

Explanation:
Density is defined as the ratio of the mass to the volume. The expression for density is:
The Si unit for density is kg/m³
The dimensional expression for density = [ML⁻³]
Specific volume is defined as the ration of the volume to the mass. It is the reciprocal of density.
The BG unit of specific volume is ft³ / lb.
