See attached file. Assume the earth to be a uniform spherical planet, mass M= (5.98 E 24) kg. (The number, in scientific notation, means '5.98 times 10 to the 24') The earth's radius is R= (6.37 E 6) m. Part a. Find the force of gravity between the earth and a spacecraft whose mass is m= 36000 kg, which is at height h=

Imagine that you have a solid cube composed of Material X. You put the cube into a beaker filled with water. The cube sinks to the bottom of the beaker and sits there, at rest, on the bottom. Which of the following statements are true? (Give ALL correct answers: B, AC, BCD, ... , or None) A) The buoyant force on the cub
A ball is thrown straight upward and rises to a maximimum height of 16m above its launch point. At what height above its launch point has the speed of the ball decreased to 1/2 its initial value?
