A variable-length air column is placed just below a vibrating wire that is fixed at both ends. The length of the air column open at one end is gradually increased from 0 until the 1st position of resonance is observed at 20 cm. The wire is 115.4 cm long and is vibrating in its third harmonic.
Find the speed of transverse waves in the wire if the speed of sound in air is 340 m/s. Answer in units of m/s.

This is important 1. what happens to the speed of molecules in water vapor when it condenses to form a liquid? (2 points) the molecules slow down. the molecules speed up. the molecules slow down and then speed up. the molecules speed up and then slow down. 2. how might human activities change to compensate for a decrease in water supplies? (2 points) humans might build a factory. humans might build drainage systems. humans might extract more water from the ground. human behavior does not change because of the water cycle. i'll be grateful if anyone can answer these 2 questions !

The flame produced by the burner of a gas (propane) grill is a pale blue color when enough air mixes with the propane (c3h8) to burn it completely. for every gram of propane that flows through the burner, what volume of air is needed to burn it completely? assume that the temperature of the burner is 195.0°c, the pressure is 1.05 atm, and the mole fraction of o2 in air is 0.210.
