The escape velocity is a function of a planet’s radius and mass. We also know that the mass of an object is M = ρV where ρ is the mass density and V is the volume. The volume of a sphere is V = (4/3) π R3 a.) combine the formula for the escape velocity with the additional relationships given above and find an expression for the escape velocity as a function of the mass density and radius of a...

A 1320 kg geosynchronous satellite orbits a planet similar to Earth at a radius 193000 km from the planets center. Its angular speed at this radius is the same as the rotational speed of the Earth, and so they appear stationary in the sky. That is, the period of the satellite is 24 h . What is the force acting on this satellite? Answer in units of N. What is the mass of this planet? Answer in units of kg....

A 507 kg satellite is in a circular orbit at an altitude of 754 km above a planet’s surface. This planet is similar to our Earth. Because of air friction, the satellite eventually is brought to the Earth’s surface, and it hits the Earth with a speed of 3 km/s. The radius of the planet is 7 × 106 m and its mass is 8 × 1024 kg. The gravitational constant is 6.67259 × 10−11 N m2 /kg2. How much...

2. Atmospheric Mass Venus and Earth have about the same mass and radius, but the atmospheric pressure on the surface of Venus is measured to be 90 times larger than the pressure at the surface of the Earth. (a) Assuming Venus' atmosphere is pure CO2 and Earth's atmosphere is pure N2, estimate the atmospheric scale height for each planet. For simplicity you can assume that both atmospheres are isothermal with T = 550 K for Venus and T = 250...
