A space probe has a period of 100 minutes around the earth at an altitude of 83 km about the earth's surface? Can we tell if a stable orbit is present?

A planet is orbiting a star when the star’s gravity suddenly vanishes. The planet then obeys Newton’s First law and heads outward along a straight line. Is Kepler’s second law still obeyed? That...

A satellite orbiting the earth has a speed of 5.5 km/s when its distance from the center of the earth is 11,000 km. Is the satellite in a bound orbit? I have already calculated that...

Would it be bound if it's orbital radius is larger than the radius of the planet it is orbiting ?

How much work would be done launching a 400 kg weather balloon to an altitude of 50 km? I'm supposed to use the equation PE = Gm1m2(1/di - 1/df) but have no idea how this equation...

A planet has masses ( m1) and has at a distance ( r1), from the sun. a second planet has mass(m2) equal to (m1) at a distance of r2=2r from the sun . Determine the ratio of the gravitational force...

The gravitational force, F, between an object and the Earth is inversely proportional to the square of the distance from the object and the center of the Earth. If an astronaut weighs 209 pounds...

An astronaut has a mass of 80 kg, but on an unknown planet, the bathroom scale reads 15 kg when the astronaut stands on it. What is the astronaut's weight and the gravitational field strength on the...

I have an assignment due in a couple of hours for astronomy. I've been working on this for a few hours now, but I'm not really familiar with algebra. Any help would be greatly appreciated! The question...

A uniform chain of length 'l' is placed on a smooth horizontal table, such that half of its length hangs over one edge. It is released from rest, the velocity with which it leaves the tables is ______...

A weightlifter holds a 150 kg weight 2 m from the floor. Calculate the speed which the weight hits the floor when dropped. You may assume that no energy leaves the system, and that the gravitational...

if yes then how do we get acceleration as 9.81

Here is the intro. Radio waves are also examples of electromagnetic waves. when you listen to a radio stationm the frequency that you find on the dial describes the frequency of the waves sent out...

1. what happens to the gravitational force between two objects if the distance between them is increased 4 times? a. increased 4 times b. increased 16 times c...

what is the unit force used in gravity calculations And why is it called this?

we everybody knows that there is pull of earth means gravity .then why it is so that every tree grows upward and the height of human being also grows upward?

A 7kg bowling ball is raised 1.5m into the air. What is the bowling ball's gain in gravitational potential energy? SHOW WORK PLEASE! THANKS!!!!!

A planet has ? the density of earth but 2x the radius. find the surface gravitational force on this planet. (Hint: Earth’s is 10N/Kg)
