Compute the length of a pipe that has a fundamental frequency of 370 Hz for each of the following conditions. (Take the velocity of sound in air to be 343 m/s.)
a) Assume the pipe is closed at one end.
b) Assume the pipe is open at both ends.
Suppose a 1.17×104 kg spaceship left Earth at a speed of 0.90c. What is the spaceship's kinetic energy? Compare with the total U.S. annual energy consumption (about 10^20 J).
