The small piston of the hydraulic press with an area of 20 cm² is subjected to a force of 200 N and has lowered by 50 cm. What force acts on a large piston with an area of 0.01 m² and to what height did it rise? (I already found out that large piston force is 1000N how do I calculate in what height did it rise?)

Two friends are having a conversation. anna says a satellite in orbit is in freefall because the satellite keeps falling toward earth. tom says a satellite in orbit is not in freefall because the acceleration due to gravity is not 9.80 m/2 . who do you agree with and why?
