I don't get Physics at all and I need to have this take home test done by the end of the day today. If you could please work these problems out for me and possibly give me the answer that would be great. Problem 7: Find the power developed by an engine with torque 1110 N m applied at 5500 rpm. Problem 8: A motor turning at 1500 rpm is fitted with a gear having 50 teeth. Find the speed of the driven gear if it has 40 teeth. Problem 9: The larger of the two gears in a clock has 36 teeth and turns at a rate of 0.50 rpm. How many teeth does the smaller gear have if it rotates at 1?50 rev/s? Problem 12: Two people are standing 3.00 m apart. The first one has a mass of 85.0 kg and the second's mass is 98.0 kg. Find the gravitational attraction between the two people.
