Textbook Question

Chapter 24, Problem 80GP

Predict/Calculate When a certain resistor is connected to an ac generator with a maximum voltage of 15 V, the average power dissipated in the resistor is 22 W. (a) What is the resistance of the resistor? (b) What is the rms current in the circuit? (c) We know that P av = I rms 2 R , and hence It seems that reducing the resistance should reduce the average power. On the other hand, we also know that P a v = V r m s 2 / R , which suggests that reducing R increases p_av. Which conclusion is correct? Explain.

Your blood pressure (usually given in units of "mm of Hg") is a result of the heart muscle pushing on your blood. The left side of the heart creates a pressure of 115 mm Hg by exerting a force directly on the blood over an effective area of 14.5 cm2. What force does it exert to accomplish this? (Give your answer as the number of Newtons and note that you will need to do some unit conversions.)

What is the absolute (total) pressure experienced by a diver at a depth of 17 meters below the surface of a lake? Assume that atmospheric pressure at the surface of the lake is 101,000 Pascals, g= 9.8 m/s2, and the density of the water in the lake is 997 kg/m3. Give your answer as the number of Pascals.
