1) A piano tuner hears one beat every 1.3 s when trying to adjust two strings, one of which is sounding 350 Hz. How far off in frequency is the other string?

2) A source emits sound of wavelengths 2.64 m and 2.81 m in air. a) How many beats per second will be heard? (Assume T=20?C.) B)How far apart in space are the regions of maximum intensity?

3) A hiker determines the length of a lake by listening for the echo of her shout reflected by a cliff at the far end of the lake. She hears the echo 3.7 s after shouting. The speed of sound in air is 343 m/s. determine the length of the lake.

4) What is the resultant sound level when an 83 dB sound and an 86 dB sound are heard simultaneously?

A piano tuner hears a beat every 1.60 s when listening to a 272.0 Hz tuning fork and a single piano string. What are the two possible frequencies (in Hz) of the string? (Give your answers to at least one decimal place.) f = Hz (Smaller Value) f = Hz (Larger Value)

While attempting to tune the note C at 2093 Hz, a piano tuner hears 6.00 beats/s between a reference oscillator and the string.

While attempting to tune the note C at 2093 Hz, a piano tuner hears 6.00 beats/s between a reference oscillator and the string.(a) What are the possible frequencies of the string?Lower possible frequency=2087 Hz/ Higher possible frequency=2099 Hz (b) When she tightens the string slightly, she hears 7.00 beats/s. What is the frequency of the string now? 2100 Hz(c) By what percentage should the piano tuner now change the tension in the string to bring it into tune? (Give a positive...

The water diet requires one to drink two cups of water every half hour from when one gets up until one goes to bed, but otherwise allows one to eat whatever one likes. Five adult volunteers agree to test the diet. They are weighed prior to beginning the diet and after six weeks on the diet. The weights (in pounds) are Person 1 2 3 4 5 Weight before the diet 180 125 240 150 160 Weight after six weeks 165 126 230 149 140 Is there evidence that the diet leads to weight loss?...

A 1 solar mass star has two planets. One is observed to transit every year and the other twice a year. If their orbits are circular, how can you determine the distance between their orbits? How could the transits show that they are circular? How might transit observations provide estimates of the density of the planets? How could you tell if the orbits were parallel to the star's spin axis?
