Agas undergoes a process in a piston–cylinder assembly during which the pressure-specific volume relation is pv1.1 = constant. the mass of the gas is 0.4 lb and the following data are known: p1 = 160 lbf/in.2, v1 = 1 ft3, and p2 = 390 lbf/in.2 during the process, heat transfer from the gas is 2.1 btu. kinetic and potential energy effects are negligible. determine the change in specific internal energy of the gas, in btu/lb.

Current enters a circuit at a: 1.positive terminal 2.negative terminal 3.low potential side 4.resistor

Imagine you had to physically add electrons, one at a time, to a previously neutral conductor. you add one electron very easily, but the second electron requires more work. in your initial post to the discussion, explain why this is. also, what happens to the work needed to add the third, fourth, fifth, and subsequent electrons

2.22/3.33 points | previous answers tamucolphysmechl1 4.pre.002. ask your teacher my notes question part points submissions used on a frictionless air track, a blue glider with mass 0.200 kg is moving to the right with a speed of 8.00 m/s. it strikes a red glider that has mass 0.600 kg and that is initially at rest. after the collision, the blue glider is moving to the left with a speed of 2.40 m/s. (a) what are the magnitude and direction of the velocity of the red glider after the collision? magnitude 3.33 m/s correct: your answer is correct. direction correct: your answer is correct. (b) is this collision elastic?
