A ball rolls at a constant 100 feet per minute as it approaches a hill. It then rolls down the hill gaining speed. At the bottom of the hill, it is going at 300 feet per minute. If it took 2 minutes to roll down the hill, then what is the distance from the top of the hill to the bottom of the hill?

Which statement about covalent bonds is true

An object resting on a table weighs 100 n. with what force is the object pushing on the table? with what force is the table pushing on the object? explain how you got your answer.

During the experiment if you could triple the breakaway magnetic force with all other quantities left unchanged, what is the new value for the critical velocity if it was v0 (initial velocity), initially? (b) now if you halved the radius with all other quantities left unchanged, what is the new critical velocity if it was v0 (initial velocity), initially? (c) if during the experiment, critical velocity quadrupled with all other quantities left unchanged, what is the new breakaway force if its magnitude was initially f0,?
