Mars in a Minute: How Did Mars Get Such Enormous Mountains?

How did Santosh begin to climb mountains?

A spaceship is stationed on Mars. How much energy must be expended on the spacesship to rocket it out of the solar system ? Mass of the spaceship 1000 kg, mass of the sun= 2xx10^(30) kg, mass of Mars= 6.4xx10^(23) kg, radius of Mars 3395 km, radius of the orbit of Mars = 2.28xx10^(8) Km, G= 6.67xx10^(-11)Nm^(2)Kg^(-2).

Mars is the nearest planet to the Earth.

In the echo method of estimating distnces, a radar signa was sent towards the Mars. If the echo was received after 8 minute 20 second, how far wat the Mars from the earth at that instant?

A space-ship is stationed on Mars. How much energy must be expended on the spaceship to rocket it out of the solar system ? Mass of the spaceship = 1000 kg , Mass of the sun = 2 xx 10^(30) kg . Mass of the Mars = 6.4 xx 10^(23) kg , Radius of Mars = 3395 km . Radius of the orbit Mars = 2.28 xx 10^(11) m, G = 6.67 xx 10^(-11) N m^(2) kg^(-2) .

Find the period of revoluition of planet Mars about the sun if mean distance of the Mars from the sun is 1.52AU.

A body weight 45 kg wt on the surface of earth. Its weight on the surface of Mars will be [Mass of Mars = (1/9) mass of earth, Radius of Mars = (1/2) Radius of earth]
