How far away is a cliff if an echo is heard 0.435 s after the original sound? Assume that sound traveled at 343 m/s on that day.
A motion sensor emits sound, and detects an echo 0.0115 s later. A short time later, it again emits a sound, and hears an echo after 0.0183 s. How far has the reflecting object moved? (Please put answer to at least 3 sig figs) A motion sensor emits sound, and detects an echo 0.0115 s after. A short time later, it again emits a sound, and hears an echo after 0.0183 s. How far has the reflecting object moved? (Speed...
How many meters away is a cliff if an echo is heard 0.500 s after the original sound? Assume that sound traveled at 343 m/s on that day.
When needed, use 340 m/s for the speed of sound and 3.00 x 108 m/s for the speed of light. A hiker determines the length of a lake by listening for the echo of her shout reflected by a cliff at the far end of the lake. She hears the echo 2.20 s after shouting. How long is the lake?

1-5 test prep please help Waves A fisherman notices that wave crests pass the bow of his anchored boat every 3.0 s. He measures the distance between two crests to be 6.5 m. How fast are the waves traveling? 2. A sound wave in air has a frequency of 262 Hz and travels with a speed of 343 m/s. How far apart are the wave crests (compressions)? io signals have frequencies between 550 kHz and 1600 kHz and travel with...
(a) The man hears the sound of the splash 2.92 s after he releases the rock from rest. The speed of sound in air (at the ambient temperature) is 336 m/s. How far below the top of the well is the surface of the water? (b) If thet Show My Work (optional
A person runs away from the speaker at 3 m/s, while it creates a 200 Hz sound wave. What frequency does the person hears? Take 340 m/s as the speed of sound.

A woman drops a rock into a well. The woman hears the sound of the splash 1.50 seconds after releasing the rock. The speed of sound in the w is 336 m/s. a. Show a velocity-time graph for the rock as it falls from the surface down the well, and the sound of the splash as the sound comes up the well. b. How far below the top of the well is the surface of the water?
