A bat flying in a cave emits a sound and receives its echo 0.8 s later How far away is the cave wall?
to solve this you can use the equation d=vt
you are already given the time which for you is 0.8s
the velocity would be the speed of sound in air which is 343m/s
then you just have to plug in all in and you get 274.4m
but since it's an echo it covers the length of the cave twice so you would have to divide the distance by 2 which gives you:
137.2m

That's arithmetically correct but are there any bats with an echo-locating range that large? From what I've read they are lucky to receive echoes from anything more than about 10m away, for although they can call at very high intensities their voice power is very low. Also, cave walls are irregular and even if highly reflective would scatter a large proportion of incident sound, reducing the echo strength considerably. It would be very interesting - assuming it could be done - to determine what they form in their brains from their echo-locating. Is it an image slightly like that of a sidescan-sonar, or simply an indication of an obstacle?
What else can I help you with?
A bat flying in a cave emits a sound pulse and receives its echo 1.1 s later How far away is the cave wall?
16.5m aka 1650cm and 16500mm and u suck toms chubby cheeks
A sound source of high frequency emits a high?
It emits a high pitch
What is an audio source?
A thing that emits sound
A bat flying in a cave emits a sound pulse and receives an echo in 2 seconds. How far away is the cave wall?
The sound wave travels to the wall and back in 2 seconds, so the total travel time is 2 seconds. To find the distance, divide the total time by 2 (since the sound has to travel there and back), giving a distance of 1 second for the sound wave to reach the wall. Multiply this time by the speed of sound in air (approximately 343 m/s) to find the distance, which is about 343 meters.
What is an emitter?
Something that emits a force. Such as an EMP or a sound wave.
Which type of device emits a sound wave to measure to the ocean floor?
SONAR
What receives sound sound vibration and relays it to the auditory nerve fibers?
Organ of corti
What is the function of the incus?
receives the sound waves by the malleus.
What note on the piano emits the sound of 400 hz?
G sharp comes the closest!
What instrument emits a sound wave to measure the ocean floor?
A sonar instrument emits sound waves to measure the ocean floor. The sound waves travel through the water and bounce back when they hit the seafloor, allowing the instrument to calculate the depth and map the topography of the ocean floor.
What is a mach number in aeroplanes?
The mach number is the speed of an aircraft, expressed as a fraction of the speed of sound in the atmospheric conditions in which the aircraft is flying. An aircraft flying at mach 1 is flying at the speed of sound.
Do ears work like loudspeakers?
No, because the loudspeaker creates sound while the ear receives sound.
