In fig. 7-30, a block of ice slides down a frictionless ramp at angle 50 while an ice worker pulls on the block (via a rope) with a force that has a magnitude of 50 n and is directed up the ramp. as the block slides through distance d 0.50 m along the ramp, its kinetic energy increases by 80 j. how much greater would its kinetic energy have been if the rope had not been attached to the block?

A30 kg weight lies on top of a massless piston of area a = 0.01 m2 the exterior air is at a (constant) p =1 atm and t = 27 c. the interior gas is 0.4 moles of (ideal) n2 and it has initial temperature 27.00 degrees c. 1. what is the initial pressure in the interior? a. 29.4 kpa b. 130.7 kpa c. 101.3 kpa the next three questions concern what happens when an amount of heat q is slowly added to the interior, raising the piston by 1 mm and raising the interior temperature to 27.40 c
