Three objects of uniform density- a solid sphere, a solid cylinder, and a hollow cylinder- are placed at the top of an incline. they are all released from rest at the same elevation and roll without slipping. a) which object reaches the bottom first? b) which reaches it last? c) try this at home and note that the result is independent of the masses and the radii of the objects.

10 points! will mark brainiest! in a heat engine if 1,000 j of heat enters the system and the piston does 500 j of work, what is the final internal energy of the system if the initial energy was 2,000 j 1: write the equation2: list out your known variables 3: plug the numbers into the equations 4: solve 5: write your solution statement that includes initial energy and final energy added you so much!
