Find work done in shifting a body of mass m from a height h above the earth's surface to a height 2h above the earth's surface.

Find work done in shifting a body of mass m from a height h above the earth's surface to a height 2h above the earth's surface..

Certain characteristic wavelength in the light from a galaxy in the constellation virgo are observed to be increased in wavelength, as compared with terrestrial sources, by about 0.4% . What is the radial speed of this galaxy with respect to earth ? Is it approacing or receding ?

The wavelength of light received from a galaxy is 10% greater than that received from identical source on the earth. The velocity of the galaxy relative to the earth is
