You are studying guitar strings and are able to measure a few of (but not all) the standing wave frequencies for a particular string. If you measure frequencies of 540 Hz,900 Hz, 1440 Hz, and 1620 Hz, what is the highest possible value for the fundamental frequency?
Two speakers, one directly behind the other, are each generating a 429-Hz sound wave. What is the smallest separation distance between the speakers that will produce destructive interference at a listener standing in front of them? Take the speed of ..
One mole of an ideal gas is heated so that T = AP2, where A is a constant and P is the pressure. The temperature changes from T0 to 4T0. Find out the work completed by the gas. (Use the following as necessary: T0, P0, and V0.)
