A planet has a mass of 2.4xx10^(26) kg with a diameter of 3xx10^(8) m. What will be the acceleration due to gravity on that planet ?

A spherical ball of radius 3.0xx10^(-4) m and density 10^(4)(kg)/(m^(3)) falls freely under gravity through a distance H=nxx500m before entering a tank of water. If after enerting the water the velocity of the ball does not change, then find n. viscosity of water is 10xx10^(-6)(N-s)/(m^(2)) , g=10(m)/(s)

A spherical ball of radius 3xx10^(-4) m and density 10^(4)kg//m^(3) falls freely under gravity through a distance h before entering a tank of water. If after entering the water the velocity of the ball does not change, find h the viscosity of water is 9.8xx10^(-6)N-s//m^(2)

What will be the escape speed from a planet of mass 6xx10^(16) kg and radius 3.6xx10^(4) m ?

A metallic sphere of radius 1.0 xx 10^(-3) m and density 1.0 xx 10^(4) kg//m^(3) enters a tank of water, after a free fall through a distance of h in the earth's gravitational field. If its velocity remains unchanged after entering water, determine the value of h . Given: coefficient of viscosity of water = 1.0 xx 10^(-3) N s//m^(2), g = 10ms^(-12) and density of water = 1.0 xx 10^(3) kg//m^(3) .

If an oil drop of density 0.95xx10^(3)kg//m^(3) and radius 10^(-4) cm is falling in air whose density is 1.3 kg//m^(3) and coefficient of viscosity is 18xx10^(-6)kg//(m-s) . Calculate the terminal speed of the drop.
