1. A rover mission to another planet attempts to measure the value of g using a simple pendulum. Using a pendulum of length 45.0 cm , the rover measures 105 complete swings in a time of 145 s. What is the value of g on this planet?
2. The frequency of the note F4 is 349 Hz .
a) If an organ pipe is open at both ends, what length must it have for its fundamental mode to produce this note at a temperature of 20.0 ∘C?
b) At what air temperature will the frequency be 362 Hz ? (Ignore the change in length of the pipe due to the temperature change.)

A string with a mass per length of 2.00 g/m is stretched with a force of 120 N between two points that are 0.400 m apart. The fundamental frequency of the stretched string is in tune with the frequency of the second mode of an organ pipe filled with air at −20°C and open at both ends. The speed of sound in air at 0°C is 331 m/s. What is the length of the organ pipe?

A certain organ pipe, open at both ends, produces a fundamental frequency of 290 Hz in air. If the pipe is filled with helium at the same temperature, what fundamental frequency f_He will it produce? Take the molar mass of air to be 28.8 g/mol and the molar mass of helium to be 4.00 g/mol Express your answer in hertz. Now consider a pipe that is stopped (i.e., closed at one end) but still has a fundamental frequency of 290...

Part A: A certain organ pipe, open at both ends, produces a fundamental frequency of 300 Hz in air. If the pipe is filled with helium at the same temperature, what fundamental frequency fHe will it produce? Take the molar mass of air to be 28.8 g/mol and the molar mass of helium to be 4.00 g/mol. I calculated this correctly to be 879 Hz, but I am not sure about the next part. Now consider a pipe that is...

A simple instrument consists of two metal strings stretched parallel to one another and attached at both ends to boards perpendicular to the strings. The tension is the same in both strings, and the length of the strings is ` = 35.0 cm. The first string has a mass m = 8.00 g and generates middle C (frequency f = 262 Hz) when vibrating in its fundamental mode. a) What is the tension in the first string? b) If the...
