An 80 kg man standing on a planet experiences a weight of 600 N. The radius of the planet is 5.4 x 10° m. Determine the mass of the planet?

Determine the gravitational field at mass A. The radius of masses A and C is 50 cm while the radius of mass B is 75 cm.

The International Space Station (ISS) is a space station orbiting the earth above the ground. If the radius of the earth is 3,958.8 miles, mass of earth is 5.972 x 10 24 kg,  the period of the ISS at the orbit around the earth is 14.137 hours, can you calculate what is the distance from the ISS to the surface of the earth, in unit of miles? Use G=6.674 x 10 -11 Nm2/kg2. Write your answer in pure numbers, for example, 4567.8. Please keep at least on digit after the decimal point.

On a planet whose radius is 1.80 × 104 km, the acceleration due to gravity is 16.5 m/s?. What is the mass of the planet?

Scientists have discovered a distant planet with a mass of 8.2x1023 kg. The planet has a small moon that orbits with a period of 6 hours and 36 minutes. Use only this information (and the value of G) to calculate the radius of the moon's orbit (in units of 106 m).

On the Earths surface, the gravitational field strength is about 9.8 m/s2 . Now considering a different planet with a mass of 7.4 x 1023 kg with a gravitational field strength at its surface of 5.3 m/s2 . What is the diameter of this planet?

Where required use Mass of Earth 6 x1024 Kg and radius of earth = 6.4 x106 m. density of Earth p =5200Kg/m³

The International Space Station (ISS) is a space station orbiting the earth above the ground. If the radius of the earth is 3,958.8 miles, mass of earth is 5.972 x 10 24 kg, the period of the ISS at the orbit around the earth is 7.89 hours, can you calculate what is the distance from the ISS to the surface of the earth, in unit of miles? Use G-6.674 x 10-11 Nm2/kg2. Write your answer in pure numbers, for example, 4567.8. Please keep at least on digit after the decimal point.

The planet Krypton had a surface gravitational field strength of 13.5 N/kg. a) if Superman weighed 1054N on Krypton, how much would he weigh on Earth? b) if Krypton had a radius of 1.6 x 104 km, what would its mass have been?

At a particular instant the magnitude of the gravitational force on a moon due to the planet it orbits is 6.73×1022 N. The mass of the moon is 8.9×1022 kg and the mass of the planet is 2.0×1027 kg. What is the distance between the center of the planet and the center of the moon? (a) 5.14 × 1013 m(b) 1.77 × 1017 m(c) 1.41 × 103 m(d) 9.41 × 106 m(e) 4.21 × 108 m
