One technique of estimating the length of a metal is by recording the time it takes for a pulse to travel from one end to the other.  The student finds that the time is 0.00349 s. The Young’s modulus of metal 127325340650 is N/m2; and its density is 9260 kg/m3. How long is the rod?

A copper block is suspended from a wire, as in part 1 of the drawing. A container of mercury is then raised up around the block, as in part 2, so that 42.0% of the block's volume is submerged in the mercury. The density of copper is 8890 kg/m³, and that of mercury is 13 600 kg/m³. Find the ratio of the fundamental frequency of the wire in part 2 to the fundamental frequency in part 1. f1,Part 2/f1. Part 1 Number i = Copper block Part 1 Units I M Part 2

How long will it take to hear an echo if you are 487.54 meters from a canyon wall and sound travels as 345.73 m/s?

A student shares a surgical tubing in the lab. The tension on the tubing is 50N. The student measures the fourth frequency of the tubing to the 20 Hz. The length of the tubing is 2m. Calculate the mass of the tubing

The light intensity (3.431x10^2) cm from a point source is (1.3730x10^0) kW/m². What is the intensity (2.32713x10^2) m away from the same source? Express your result with four significant figures in W/m². Note: Your answer is assumed to be reduced to the highest power possible.

The highest frequency that we can hear is about 20 kHz (2x 10^4Hz). a) Calculate the wavelength (m) associated with this frequency for sound that travels at 345 m/s. b) How long is this in feet? (Roundanswers to the nearest tenth.

There is a tube of length 1.0 m with one end closed. You clapped your hand at the mouth of the tube once. The echo of the clap came back after 6.0 milliseconds. What is the velocity of sound in the tube ? 330 m/s O 320 m/s 290 m/s O 170 m/s

For testing purposes, a musical instrument manufacturing company creates a device so that when you blow into one end with your instrument, sound comes out the other end in opposite directions. A sound technician uses a whistle and generates sound waves with a frequency of 242 Hz. The waves travel in opposite directions in a band room, are reflected by end walls, and return. The band room is 44.0 m long and the whistle is located 14.0 m from one end. What is the phase difference (in degrees) between the reflected waves when they meet at the source of the sound? The speed of sound in air is 343 m/s.

You are part of a scientific expedition that landed in the planet Martech. The planet has an atmosphere of an unknown gas. In your preparation for the mission you prepared the following table, a resonance tube and a sonic device that can produce three frequencies: 261HZ, 330HZ and 512HZ. Temperature (°c Speed (m/sec) Substance CO2 258 CO2 20 267 Air 331.5 Air 20 344 Water Vapor Helium Hydrogen 20 395 20 927 1,270 Argon 20 300 Delakium 20 2950 You measured the temperature of the gas in the atmosphere and recorded 20 degree Celsius. Remembering the valuable learning experience you had in your class Science and Technology in the Arts, you need to determine the gas of the atmosphere on the planet Martech. When rushing to implement the experiment, you used the sonic device to produce the three frequencies above the resonance tube, but recorded only the length of the resonance tube that produced the first maximum intensity for each one of them without recording the frequency of the sonic…
