A stone is dropped from the top of a cliff. The splash it makes when striking the water below is heard 2.7 s later. Considering the speed of sound in air at 20 °C to be 343 m s-¹ and considering the gravitational acceleration to be 9.80 m. s-², How high is the cliff?

This is possibly a different atmosphere from ours.  In any case, the speed of sound is computer-generated, and is 454 m/s this time.  Light travels for us instantaneously. You see a lightning flash, and 7.6 seconds later, you hear the thunderbolt.  How far away was the lightning (in meters)?

The highest natural atmospheric temperature ever recorded on Earth was 58oC (136oF), at El Azizia, Libya on September 13, 1922. The record low temperature was -89oC (-129oF), which occurred at the Soviet Vostok Station in Antarctica on July 21, 1983. What is the difference in the speed of sound in air for these two extreme temperatures? answer in m/s.

V= 331m/a + (0.6m/s degrees Celsius )T Determine the speed of sound on a cold winter day(T=3degrees C)

The speed of sound in a solid medium is 15 times greater than that in air. If the frequency of a wave in the solid is 61 kHz, then what is the wavelength? (The speed of sound in air is 344 m/s.)

A Moving to another question will save this response. Question 2 If the speed of sound in air at 0 °C is 331 m/s. What will be the speed of sound in air at 50 °C? 299 m/s 142 m/s 331 m/s 360 m/s None of these. AMoving to another question will save this response. ch 45

sound waves in air ( v = 343 m/s ) has a frequency of 320 Hz. In ocean water, its wavelength is 4.875 m. What is the speed of sound in seawater? 343 m/s 1005 m/s 1300 m/s 1440  m/s 1560 m/s

An enormous thunderstorm covers Dallas-Ft. Worth. Your best friend Clark is a storm chaser and heads to the center of the storm to take some readings while you stay dry at home. While Clark is at the center of the storm, he sees and hears lightning strike a tree that is 185 m from where he is standing. You are 134 km from the tree. How long does it take for the sound to reach Clark? Assume the speed of sound is 343 m/s. How long does it take for the light to reach you?

In the upper atmosphere at altitudes where commercial airlines travel, we find extremely cold tempera-tures. What is the speed of sound (in metric units) for a temperature of -55 ◦ C? Calculate to one decimal.

The loudness, L, of a sound (measured in decibels, dB) is inversely proportional to the square of the distance, dd, from the source of the sound.A person 14 feet from a jetski, it is 75 decibels loud.How loud is the jetski when the person is 46 feet away? Round your answer to the nearest hundredth.
