The atoms of the particular medium in which the sound is produced moves backward and forwards in sound.
The laws of momentum. The boat is on a frictionless surface (water). The engine turns the propeller, which forces water backwards at speed. Since there is nothing to stop the boat moving - it moves forwards.
The density of air increases and then decreases as the sound wave passes.
The formula is usually expressed as: e = mc2 To "reverse" this, I guess you would simply want to solve for "m". To do this, exchange the left and right part of the equation. Then divide both sides by c2.
Sound waves can bounce backwards and forwards many times before they die out.When sound waves reflect off walls, two things happen:They take longer to reach the listener.They lose energy (get quieter) with every bounce.
Yes
When sound moves forwards and backwards rapidly, it is called oscillation. This back-and-forth movement is what creates sound waves.
A swing!
Words that sound the same backwards as spoken forwards are called palindromes, such as "radar" or "level."
The eardrum (tympanic membrane) moves backward and forward in response to sound waves, which then causes the tiny bones in the middle ear to vibrate and transmit the sound to the inner ear.
The tympanic membrane, or ear drum. A thin piece of skin inside the ear that moves backwards and forwards when sound waves reach it
The truck is heavier
no bird can only move backwards! only a hummingbird has the ability to move backwards but it also moves forwards and left to right!
A palindrome sound a chick makes is "peep." It is the same forwards and backwards.
"Wow" is a palindrome for a sound of surprise, as it reads the same forwards and backwards.
The word is palindrome. For example “Madam” is the same read backwards or forwards.
backwards
