A satellite of mass 3000 kg orbits the Earth in a circular orbit of radius of 6.6 × 10^6 m (this is above the Earth's atmosphere).The mass of the Earth is 6 × 10^24 kg.

a. What is the speed of the satellite?
b. What is the minimum amount of energy required to move the satellite from this orbit to a location very far away from the Earth?

Imagine that you have two balloons (or, better yet, actually inflate two balloons, if possible). create static electricity around one of the balloons by rubbing it against your hair or your sweater and then bring that balloon close to the other balloon, which has not been charged. try this with at least one other object—and for variety in the discussion, avoid using an object already described by your classmates. then, for your initial post to the discussion, answer the following questions: what happened with the two balloons?

Aball of mass 0.3kg is released from rest at a height of 8m. how fast is it going when it hits the ground? accleration due to gravity is g=9.8m/s

Aweather balloon has a volume of 52.5 liters at a temperature of 252 k. the balloon is released and rises to an altitude where the temperature is 295 k. how does this temperature change affect the gas particle motion?
