The dot in Fig, 19-18 a represents the initial state of a gas, and the vertical line through the dot divides the p-V diagram into regions 1 and 2. For the following processes, determine whether the work W done by the gas is positive, negative, or zero: (a) the gas moves up along the vertical line, (b) it moves down along the vertical line, (c) it moves to anywhere in region 1, and (d) it moves to anywhere in region 2. Figure 19-18 Questions 4, 6, and 8.

A small postage stamp is placed in front of a concave mirror (radius = 1.1 m), such that the
image distance equals the object distance. (a) What is the object distance? (b) What is the
magnification of the mirror (with the proper sign)?
Calculate the anti-clockwise torque and the clockwise torque of the system with the ruler and the washers. Record these values in Data Table 5. Ruler = 11.56 g, small washer = 1.85 g, large washer = 24.30 g.
Calculate the % Difference in the Torques and record the values in Data Table 5.
Is ΣAnticlockwise torque and Anticlockwise torque the same thing, are they solved in the same way?
A window washer stands on a uniform plank of mass M = 142 kg and length l = 2.80 m supported by 2 ropes attached at the ends of the plank. The window washer has a mass m = 68.0 kg. What is the tension in each of the ropes, T1 and T2, if the window washer's displacement from the center of mass of the plank is x = 0.930 m as shown in Figure 1: Window Washer Problem?
