A 2.0 kg box is released from rest at a height yo = 0.25 m on a frictionless ramp. The box slides from the ramp onto a rough horizontal surface with a friction coefficient pe = 0.50.
m
y.
How far does the box slide along the rough surface?
Round answer to two significant digits.

Why there is no inductive reactance in dc circuits

In a heat engine if 1000 j of heat enters the system the piston does 500 j of work, what is the final internal energy of the system if the initial energy was 2000 j? 1. write the equation 2.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

Arigid tank is divided into two equal parts by a partition. one part of the tank contains 3 kg of compressed liquid water at 400 kpa and 60°c while the other part is evacuated. the partition is now removed, and the water expands to fill the entire tank. determine the entropy change of water during this process, if the final pressure in the tank is 40 kpa. use steam tables.
