Physics Questions

Astigmatism is a common vision condition that causes blurred vision. It occurs when the cornea is irregularly shaped or sometimes because of the curvature of the lens inside the eye.

Sound waves cannot travel through a Vacuum.

A vacuum is an area without any air, like space. So sound cannot travel through space because there is no matter for the vibrations to work in.

The combined gas law states that the ratio between the pressure-volume product and the temperature of a system remains constant.

Hence it depends on all the three Volume, Temperature & Pressure.

We know that, solids have definite shapes and definite volumes, whereas liquids have definite volumes but indefinite shapes and coming to gases it has indefinite volumes and indefinite shapes.

Hence, only in solids, the forces of attraction limit the motion of particles.
