If the motor M rotates in the direction shown by the arrow as illustrated in the diagram below, what is going on? A. 1 and 2 are going down B. 1 goes up and 2 goes down C. 1 and 2 are going up D. 1 goes down and 2 goes up 49) For the system in the diagram below to be in equilibrium, what is the mass of P in pounds? The mass at the other end of the beam is 5 kg.

C. 1 and 2 are going up

Explanation:

The motor turns counterclockwise, so the pulley above it will also turn counterclockwise.  This means the pulley to the right will turn counterclockwise.  So block 2 will move up.

Since the belt is twisted on the left side, the pulley on the left will spin in the opposite direction (clockwise).  So block 1 will also move up.

molecules are free to separate from each other and will take on the shape of the container. molecules move completely at random and high speeds. they vibrate in a fixed position and do not move around much. molecules expand to the edge of their container.
