Water skiers often ride to one side of the center line of a boat, as shown in Figure 715. In this case, the ski boat is traveling at 15 m/s and the tension in the rope is 75 N. If the boat does 3500 J of work on the skier in 50.0 m, what is the angle between the tow rope and the center line of the boat?
Chapter 17: Phases and Phase Changes An ideal gas is one that is dilute enough, and far away enough from condensing, that the interactions between molecules can be ignored If the volume of an ideal gas is held constant, we can find that the pressure increases with temperature o P = (constant)T If the volume and temperature are kept constant, but more gas is added, the pressure will increase o P = (constant)N If the temperature is constant and the volume decreases, the pressure increases o P = (constant) / V Combining all of the above equations, we create the following equation o P = k (NT/V) o K = the Boltzmann constant = 1.38 x 10^(23) J/K o PV=NkT
