You’re trying to cast a video presentation from your tablet to a projector for a training session with some new hires. Although you tested it successfully yesterday, today the connection is not cooperating. You’ve closed apps you’re not using, and you’ve checked that the projector and the tablet are working otherwise. Of the following troubleshooting steps, which should you try first? Second?

a. Restart the projector
b. Restart the tablet
c. Reinstall the presentation app.
d. Verify that you have Internet access on the tablet.

Agas contained within a piston-cylinder assembly e end nation about same energy states, 1 and 2, where pi 10 bar, v undergoes two processes, a and b, between the sam 0.1 m3, ui-400 kj and p2 1 bar, v2 1.0 m2, u2 200 kj: process a: process from 1 to 2 during which the pressure- volume relation is pv constant process b: constant-volume process from state 1 to a pressure of 2 bar, followed by a linear pressure-volume process to +20 0 state 2 kinetic and potential energy effects can be ignored. for each of the processes a and b, (a) sketch the process on p-v coordinates, (b) evaluate the work, in kj, and (c) evaluate process the heat transfer, in kj
