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

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.

b. false

explanation:

suppose a rock in free fall is dropped off a cliff. after falling for 5 seconds, its speed would not be 100 m/s.

a. spokes of a wheel.

as indicated in the question radial contains rad, also found in radius, so the fracture's would span the radius.
