pipe open at one end and closed at the other is 82 cm long. What are the three lowest frequencies to which it will resonate? Draw the wave within the tube for each frequency. Repeat for a pipe open at both ends. (104.573 Hz, 313.72 Hz, 522.87 Hz and 209.14 Hz, 418.29 Hz, 627.44 Hz)

A sound registers (2.40x10^1) decibels on a detector. What is the intensity in W/m2? Assume the threshold of human hearing is 1.0×10-12 W/m2. Use three significant figures for your answer.

Determine the wavelength of the sound for 24 Hz.   Determine the wavelength of the sound for 23 kHz.

Questions 1-6: Consider a wave on a string that can be described by the following equation: y (x, t) = 2.5 cm Sin(2.0 m-1x + 1800 s-1- 4.7) %3D 1. This is describes a... [circle one] ( sanding wave / wave traveling toward +x/wave traveling towards -x) 2. Amplitude = 3. Wavelength = 4. Frequency = 5. Wave speed% = 6. Speed of the medium att = 2.0 ms = X-0.25m

The range of human hearing extends from approximately 20 Hz to 20000 Hz. Find the wavelengths of these extremes at a temperature of 38°C. 20 Hz        m 20000 Hz        m

You pull your t-shirt out of the washing machine and note that 3500 particles have become attached, each of which could be either an electron or a proton. Your t-shirt has a net charge of − 17.5     10 - 18   C. How many electrons are attached to your t-shirt? Enter the number
