A generator consumes 147 joules of energy in fuel and produces 75 joules of energy in electricity. Engineers are challenged to produce a generator that is 20% more efficient. Which of the following combinations of input and output energy represents a generator that has met this design challenge? OPTIONS

Consider a small frictionless puck perched at the top of a fixed sphere of radius r. if the puck is given a tiny nudge so that it begins to slide down, through what vertical height will it descend before it leaves the surface of the sphere? [hint: use conservation of energy to find the puck's speed as a func e conservation of energy to find the puck's speed as a function of its height at what value of this normal force does the puck leave the sphere? ] here on the puck.
