Mars in a Minute: Are There Quakes on Mars?

The mean diameters of Mars and Earth are 6.9 xx 10^3 km and 1.3 xx 10^4 km, respectively. The mass of Mars is 0.11 times Earth's mass. (a) What is the ratio of the mean density (mass per unit volume) of Mars to that of Earth? (b) What is the value of the gravitational acceleration on Mars? (c) What is the escape speed on Mars?

Assuming the mass of Earth to be ten times the mass of Mars, its radius to be twice the radius of Mars and the acceleration due to gravity on the surface of Earth is 10 m//s^(2) . Then the accelration due to gravity on the surface of Mars is given by

The radius of the Earth is about 6400 km and that of Mars is about 3200 km. The mass of the Earth is about 20 times the mass of Mars. An object weighs 500 Non the surface of Earth. Its weight on the surface of Mars would be

The radius of earth is about 6400 km and that of Mars is 3200 km . The mass of the earth is about 10 times the mass of Mars . An object weighs 200 N on te surface of Earth . Its weight on the surface of mars will be .

The mean distance of Mars from the sun in 1.524 times that of the Earth from the sun. Find the number of years requires for Mars make one revolution about the Sun.

The radius of earth is about 6400Km and that of mars is about 3200 km The mass of the earth is about 10 times the mass of mars An object weight 200N on earth 's surface , then its weight on the surface of mars will be

Which characteristics of Mars distinguishes it from other planets ?

Phobo is a satellite of Mars. The period of its revolution around Mars is 0.319 days and its mean distance from Mars is 9.519xx10^(6)m . Assuming that the mass of Phobos is negligible compared to that of Mars, calculate the mass of Mars. Take G=6.668xx10^(-11)Nm^(-2)kg^(-2)

Talking the mass and radius of the earth as the units of mass and distance respectively, the mass of Mars turns out to be 0.107 unit and radius 0.53 units. What is the acceleration due to gravity on the Mar's surface? What will be the weight of a person on Mars if he weighs 98kg on earth.
