Vibrating or maybe fluctuating. Pulsating may describe it too.
When the speaker cone moves forward, it compresses the air in front of it, creating a high-pressure region. As the cone moves backwards, it rarefies the air, creating a low-pressure region. This rapid oscillation of high and low-pressure regions propagates through the air as sound waves.
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.
A ton, backwards it's "not"
Propulsion is the force that moves an object forward. It is the result of applying force to the object in the opposite direction it needs to move. For example, in a rocket, propulsion is generated by expelling propellant gases backwards, causing the rocket to move forward.
The person has inertia, the resistence to change in motion, so if the car starts accelerating forward, the person's body wants to stay at the same velocity as before, thus it slides backwards relative to the car. If there were no friction or a back of the seat to stop the person, the person would literally not move while the car moves out from under him, thus seeming to move backwards in the car while in reality the car is moving forward under the person.
The answer to this riddle is a "ton." It is heavy, moves forward, and when spelled backwards, it becomes "not."
"Backwards" is an adverb, not a common noun. It is used to describe the direction in which something moves or faces.
Time does not go backwards in a literal sense according to our current understanding of physics. Time always moves forward in a linear direction.
If it moves a little bit but seems like something is holding it back you should probably check your parking brake to see that it is disengaged.
When the speaker cone moves forward, it compresses the air in front of it, creating a high-pressure region. As the cone moves backwards, it rarefies the air, creating a low-pressure region. This rapid oscillation of high and low-pressure regions propagates through the air as sound waves.
(Say it by sound) backwards
A bookperson. Time doesn't move forward. Time is. People move forward or regress. Bookpeople learn, grow and always move forward.
Assuming you are talking about chess, it always moves forward. It can only move 1 step forward if already moved. If it hasn't been moved then it can move 2 forward. And it can only attack diagonally forward either to the left or right never backwards.
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.
Well force does affect as energy (Strength) of the wind/something forcing it pushes something forward and backwards like a hurricane.
A bib is something a baby wears that is also a palindrome (the same forward or backwards).bib
A car model that is spelled the same forward and backwards is a race car. As you can see RACECAR backwards is RACECAR.
