As a prank, someone drops a water-filled balloon out of a window. The balloon is released from rest at a height of 17.1 m above the ears of a man who is the target. Then, because of a guilty conscience, the prankster shouts a warning after the balloon is released. The warning will do no good, however, if shouted after the balloon reaches a certain point, even if the man could react infinitely quickly. Assuming that the air temperature is 20.0 °C and ignoring the effect of air resistance on the balloon, determine how far above the man's ears this point is.

35. ssm The speed of a sound in a container of hydrogen at 201 K is 1220 m/s. What would be the speed of sound if the temperature were raised to 405 K? Assume that hydrogen behaves like an ideal gas.

You are hiking along a trail in a wide, dry canyon where the outdoor temperature is T=28.5 degrees celsius. To determine how far you are away from the canyon wall you yell "hello" and hear the echo t=3.05s later.   a) calculate the speed of sound in the valley in meters per second, assuming the speed at 0 degrees celsius is 332 m/s b) how far are you from the canyon wall, in meters? c) if you stood at the same point on a cold morning where the temperature was T2= -1.5 degrees C, how long would it have taken for you to hear the echo, in seconds?

Speed of sound (vo) in dry air at 0°C is 331 m/s. Therefore, at room temperature (23°C) the speed (vT) will be O [331 x 296) /273)] m/s O [(331 x 23) /273] m/s O [331/(296/273)] m/s V[331 (23/273)] m/s

Rasim and Zhihan are experimenting to determine the speed of sound in m/s in air at 0°C. Assuming air to be made up of diatomic molecules with a molecular mass of 29 g/mol, what is the correct value they should expect for the speed of sound in m/s?

The coldest and hottest temperatures ever recorded in Cuba are 33.1 degrees Fahrenheight (312 K), respectively, What is the speed of sound in air (in m/s) at each temperature? (a) speed of sound at 33.1 degrees Fahrenheight (m/s) (b) speed of sound at 101.8 degrees Fahrenheight (m/s)

A flute is designed so that it plays a frequency of 268.2 Hz, when all the holes are covered and the temperature is 18.2°C. (a) What is the speed of sound in the flute? A flute is designed so that it plays a frequency of 268.2 Hz, when all the holes are covered and the temperature is 18.2°C. (b) What is the wavelength of the first harmonic? Consider the flute to be a pipe open at both ends  A flute is designed so that it plays a frequency of 268.2 Hz, when all the holes are covered and the temperature is 18.2°C. (c)Consider the flute to be a pipe open at both ends and find its length, assuming this frequency is the fundamental frequency A flute is designed so that it plays a frequency of 268.2 Hz, when all the holes are covered and the temperature is 18.2°C. A second player, nearby in a colder room, also attempts to play middle C on an identical flute. A beat frequency of 3.00 beats/s is heard.  (e) What is the speed of sound in the second room? A flute is designed so that it plays a…

On a hot summer day, the temperature of air in Arizona reaches 121°F. What is the speed of sound in air at this temperature? (The speed of sound at 0°C is 331 m/s. Use the conversion 0°C = 273 K as necessary.)

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

One way to monitor global warming is to measure the average temperature of the ocean. Researchers are doing this by measuring the time it takes sound pulses to travel underwater over large distances. At a depth of 1000 m, where ocean temperatures hold steady near 4∘C, the average sound speed is 1480m/s. It's known from laboratory measurements that the sound speed increases 4.0m/s for every 1.0∘C increase in temperature. In one experiment, where sounds generated near California are detected in the South Pacific, the sound waves travel 8300 km .If the smallest time change that can be reliably detected is 1.0 s, what is the smallest change in average temperature that can be measured?
