What is the net torque on the bar shown in the diagram below, about the axis indicated by the dot?

When you turn on a battery-operated device, an electrical circuit is

Agas contained within a piston-cylinder assembly undergoes three processes in series: process 12: compression with pv= constant from 1 bar and 1 liter to 4 bar. process 23: constant pressure expansion to 1 liter. process 31: constant volume calculate the pressure and volume at each state, and sketch the processes on a p-vdiagram labeled with pressure and volume values at each numbered stat

For the car in the picture ,in which direction is the normal force? -into the screen -down -out of the screen -up
