Which radiation coming from the sun, is prevented by the ozone layer from falling on the earth's surface?

Which gas is not present in ozone layer

How does ozone layer prevent the incidence of harmful UV-radiation on the earth's surface?

The ratio of the mass of the moon to that of the earth is 1:81. If the radius of the moon is assumed to be one-fourth of that of the earth , then what is the acceleration due to gravity on the surface of the moon in terms of that on the earth's surface ? Hence, find the escape velocity from the surface of the moon in terms of that from the earth's surface.

The ratio of the terminal velocities of two water drops while falling towards the earth's surface is 4:9 . Determine the ratio of the radii.
