How can you prove that sound is a form of energy?
You can prove that sound waves have energy by using them to do work. Consider a microphone: when you speak into it, the diaphragm vibrates (i.e. it gains kinetic energy). This shows that sound waves have the capacity to do work and therefore have energy.
How do you use sonar?
Using specialised equipment, you send out a pulses of sound. You have a collecting device where the echoing sound is picked up. You can therefore work out how long sound takes to travel to the reflecting object and back to you. If you know the velocity of sound in the medium, you can work out the distance travelled by the sound in that time and so the distance to the object is half that distance.
How do ear defenders work using a model of energy transfer?
Ear defenders do not transfer the sound waves, instead they absorb them, so as little sound as possible is transferred to the ears
How does sound energy of a bell work?
by the vibration of the whole bell , it makes a sound
How is work and enegry related?
You can store energy by doing work. And if you have energy in your body (or a system) you can do work using the energy.

On what princple does sonar and radar works?
A sonar transmits sound waves and captures it back after they strike an object. They work on the dopplers principle.
What is fish finder?
a small device sending sonar waves to find fish.
Why cant sonar find the distance between the earth and the moon?
Sonar is a sound phenominon, it requires a liquid (water, air, etc) to work.

How is sonar and echolocation alike?
An echo is like a sonar because they both reflct the sound they cause. The sonar is useful to the navy army to find out where the lost ships are located, so basically they are navigating the exact location of ships and sumbarines. An echo as you can see can be most used when screaming in the gym or an enormous place with no one in there. I hope this helped you.
How do sound systems work?
A sound system works by converting sound waves into electrical energy. The electrical energy is then converted back into solid energy that results in sound.

How does an ultra sound work?
By creating an xray using sound waves.
Give 5 differences between radar and sonar?
SONAR stands for Sound Detection and ranging, and RADAR stands for Radio Aid to Detection and Ranging. as described below (by richard), the principle is simple. Point a signal source in one direction, Listen for the echo to return, and time how long the return signal took, Divide it in two, and with some math, and knowing the speed of the wave, work out how far away the object is. Now if you make the sender/receiver directional. you can move it left and right, and see how wide the object is. If you can rotate it 360 degrees, you get a map of what is arround you. (Gavin)BY sending out a hi frequency pulse to an aircraft and detecting the timing for the return it can be calculate the speed and direction basically location of an aircraft. Sonar has the same principle applied timing of a response return PING to detect the location.Radar is a system that uses radio electromagnetic waves to provide a range to a target normal in air or a vacuum. RADAR propagates its radio waves at the speed of light. Sonar uses sound and propagates in pressure wave through water and the speed of sound. And provides a range to a target in a similar way, just at slow speed.
