A satellite orbits the Earth when the downward force exerted on it by the gravity of the Earth is just enough to provide the centripetal acceleration required to make it travel in a circular path. Assume this acceleration is the usual 9.

Do you think energy can be "used up?" Why or why not?

Which are disadvantages of series circuits? Check all that apply. They are easy to design and build. They are complicated to design and build. A break in one wire causes all current to stop.

A father racing his son has 1/3 the kinetic energy of the son, who has 1/2 the mass of the father. The father speeds up by 1.4 m/s and then has the same kinetic energy as the son. What are the original speeds of (a) the father and (b) the son
