A tube is open only at one end. A certain harmonic produced with the tube has a frequency of 485 Hz. The next higher harmonic has a frequency of 593 Hz. The speed of sound in air is 343 m/s.
1. What is the integer n that explains the harmonic whose frequency is 485 Hz?
2. What is the length of the tube?
A carnot engine operates between a hot reservoir at 310 K and a cold reservoir at 280 K. If it absorbs 500 J of heat at the hot reservoir, how much work (in joules) does it deliver?
