To determine That a force required to lift the piano is 500 N . Explanation Given: Weight of the piano, F 1 = 50 N Distance moved by the piano, d 1 = 0.2 m Distance moved by one end of the rope, d 2 = 2 m Formula used: The work done a body is given as W = F × d Here, W is the work done F is the force d is the distance Calculation: Work done required to lift the piano is calculated as W 1 = F 1 d 1 …… (1) Work done at the end of the rope is calculated as W 2 =

Learning Goal: To understand the meaning and the basic applications of pV diagrams for an ideal gas. As you know, the parameters of an ideal gas are described by the equation pV = nRT, where p is the pressure of the gas, V is the volume of the gas, n is the number of moles, R is the universal gas constant, and T is the absolute temperature of the gas. It follows that, for a portion of an ideal gas, pV = constant. Τ One can see that, if the amount of gas remains constant, it is impossible to change just one parameter of the gas: At least one more parameter would also change. For instance, if the pressure of the gas is changed, we can be sure that either the volume or the temperature of the gas (or, maybe, both!) would also change. To explore these changes, it is often convenient to draw a graph showing one parameter as a function of the other. Although there are many choices of axes, the most common one is a plot of pressure as a function of volume: a pV diagram. In this problem, you…
