How is the distance from the moon to the earth determined?

Why does moon have very cold and very hot temperature variations e.g., from -190^(@)C to 110^(@)C even though it is at the same distance from the sun as the earth is?

The distance of the centres of moon the earth is D. The mass of earth is 81 times the mass of the moon. At what distance from the centre of the earth, the gravitational force on a particle will be zero.

The distance between the centres of the Moon and the earth is D . The mass of the earth is 81 times the mass of the Moon. At what distance from the centre of the earth, the gravitational force will be zero?

The moon travels an elliptical path with Earth as one focus. The maximum distance from the moon to the earth is 405, 500 km and the minimum distance is 363,300 km. What is the eccentricity of the orbit?

A laser signal sent towards the moon returns after t seconds. If c is the speed of light then the distance of the moon from the observer is

Compare the distance of the sun from the earth and the distance of the mars from the Earth if the Sun is 1.5xx10^(8) km from the Earth and the Mars is 5.5xx10^(7) km from the Earth.

Calculate the distance from the earth to the point where the gravitational field due to the earth and the moon cancel out. Given that the earth-moon distance is 3.8 xx 10^(8) m and the mass of earth is 81 times that of moon.

Find the distance of a point from the earth's centre where the resultant gravitational field due to the earth and the moon is zero The mass of the earth is 6.0 xx 10^(24)kg and that of the moon is 7.4 xx 10^(22)kg The distance between the earth and the moon is 4.0 xx 10^(5)km .

Find the distance of a point from the earth's centre where the resultant gravitational field due to the earth and the moon is zero. The mass of the earth is 6.0xx10^24 kg and that of the moon is 7.4x10^22 kg. The distance between the earth and the moon is 4.0xx10^5km .

From two diametrically opposite points A and B on earth, moon is observed. The angle theta subtended at the moon by the two directions of observation is 1^@ 54^1 . If radius of earth is 0.638 xx 10^7 m, find the distance of the moon from the earth.
