If the atmosphere suddenly condensed into a solid mass and formed a thin layer on the siuface of the earth,what effect would it have on the time of rotation of the earth about it

It is known that if the length of the day were T0 hour, a man standing on the equator of the earth would have felt weightlessness. Assume that a person is located inside a deep hole at the equator at a distance of (R)/(2) rom the centre of the earth. What should be the time period of rotation of the earth for such a person to feel weightlessness? [R = radius of the earth]

A body weighs 10 kg on the surface of earth. What would be its mass and weight at the centre of earth ?

What is the solid crust or the hard top layer of the earth called?

The earth rotates from west to east. A wind mass begins movings due north from the equator, along the earth's surface. Neglect all effects other than the rotation of the earth. The wind mass will

If earth were to shrink suddenly, what would happen to the length of the day ?

If the radius of earth shrinks to kR (k lt 1), where R is the radius of Earth, then the time period of rotation of Earth, about its axis will become

Find the acceleration of a particle placed on the surface of the earth at the equator, due to the earth rotation. The radius of earth is 6400 km and time period of revolution of the earth about its axis is 24 h.

A planet has radius ((1)/(36)) th of the radius of the earth. The escape velocity on the surface of the planet was found to be (1)/(sqrt(6)) times the escape velocity from the surface of e earth. The planet is surrounded by a thin layer of atmosphere having thickness h (ltlt radius of the planet). The average density of the atmosphere on the planet is d and cceleration due to gravity on the surface of the earth is g_(e) . Find the value of atmospheric pressure on the surface of the planet.
