Calculate the gravitational field strength on a planet with a diameter of 15663.9 km and the escape velocity of 11 km s. Give your answer in SI units. Answer: Choose... +

The specific gravity of honey is 1.45. A cylindrical container of honey 10 feet [ft] deep is inside a dome pressurized to a surface pressure of 0.06 atmospheres [atm] on the surface of Pluto. The total pressure at the bottom of the container is 66 millimeters of mercury [mm Hg]. What is the gravitational acceleration of Pluto, in units of meters per second squared m/s?

Around 2.5 centuries ago, several physicists of the time came up with the notion of a dark star.  This was a star so dense, with so much gravity, that not even light could escape.  The calculations used Newtonian mechanics.  In class, we calculated the escape speed from the surface of the earth or the distance from the sun, and the mass of the planet or star. Here, the process is partially reversed.  Calculate the dark star radius from the mass of the star and the escape speed.  Answer in kilometers. c = 3*108 m/s M = 2.4*1030 kg G = 2/3 * 10-10 N*m2/kg2

The free-fall acceleration on the surface of a fictional planet is about 1/2 that on the surface of the Earth.. The radius of the planet is about 0.71RE (where we use the symbol RE = Earth's radius). Find the ratio of their average densities, pp/Pɛ. Please feel free to look up the earth"s radius in the table in your text-book.

An earth-like planet has a mass of 6.00×1024 kg and a radius of 7000 km. A satellite of mass 55 kg is orbiting the planet at a distance of 2000 km above the surface. What is the magnitufe of the gravitational force exerted on the satellite by the planet? (We can simplify the Gravitational Constant G to 6.7x10-11 Nm2/kg) Submit Answer Tries 0/2 What is the magnitude of the force exerted on the planet by the satellite?

What is the escape speed from a planet of mass M = 3.1 x 1023 kg and radius R = 2.6 x 106 m? Write the answer in terms of km/s.

Assume the earth's mass is 80.004 x 1025 kg, and radius is 35.532 x 103 miles, what would be the gravitational acceleration on such an planet in unit of m/s2? Use G=6.67x 10 -11 Nm2/kg2.

Gravitational force is F = Gm1m2/r². Set G = 1 and m1 = 1, where m2 will be a planet with 1800 times Earth's mass (so m2 = 1800) and 30 times Earth's radius (so r = 30). What will F be?

The International Space Station, which has a mass of 4.94×105 kg, orbits 258 miles above the Earth's surface, and completes one orbit every 94.3 minutes. What is the kinetic energy of the International Space Station in units of GJ (109 Joules)? (Note: don't forget to take into account the radius of the Earth!) Enter answer here GJ
