The moon is about 384400 km from the earth and its path around the earth is nearly circular. Find the circumference of the path described by the moon in lunar month.

The mean distance of the moon from the earth is 3.84 xx 10^5 km and it rotates around the earth in 27.3 days. What is the angular momentum of the moon around the earth ? Mass of the moon = 7.3 xx 10^(22) kg

The radius of the moon is 1//4 th the radius of the earth and its mass is 1//80 th the mass of the earth. Calculate the value of g on the surface of the moon.

The moon takes about 27.3 days to revolve around the earth in a nearly circular orbit of radius 3.84xx10^5 km . Calculate the mass of the earth from these data.

The weight of any person on the moon is about 1//6 times that on the earth. He can lift a mass of 15 kg on the earth. What will be the maximum mass, which can be lifted by the same force applied by the person on the moon?

The moon's distance from the earth is 360000 km and its diameter subtends an angle of 31' at the eye of the observer. Find the diameter of the moon.

The moon's distance from the earth is 360000 km and its diameter subtends an angle of 42' at the eye of the observer. The diameter of the moon in kilometers is

The moon's radius is 1//4 that of the earth and its mass 1//80 times that of the earth. If g represents the acceleration due to gravity on the surface of the earth, that on the surface of the moon is

The moon rotates about the earth in such a way that only one hemisphere of the mon faces the earth figure. Can we ever see the other face of the moon from the earth? Can a person on the moon ever see all the faces of the earth?

Assuming that the moon is a sphere of the same mean density as that of the earth and one quarter of its radius the length of a seconds on the moon (its length on the earth's surface is 99.2cm) is .

Take the mean distance of the moon and the sun from the earth to be 0.4 xx 10^(6) km and 150 xx 10^(6) km respectively. Their masses are 8 xx 10^(22) kg and 2 xx 10^(30) kg respectively. The radius of the earth of is 6400 km . Let DeltaF_(1) be the difference in the forces exerted by the moon at the nearest and farthest points on the earth and DeltaF_(2) be the difference in the force exerted b the sun at the nearest and farthest points on the earth. Then, the number closest to (DeltaF_(1))/(DeltaF_(2)) is :
