Awave with a frequency of 60 hz is traveling along a string whose linear mass density is 230 g/m and whose tension is 65 n. if the wave is to transfer energy at a rate of 75 w, what should the amplitude of the wave be?

Is a  vector quantity  that refers to "the rate at which an object changes its position." imagine a person moving rapidly - one step forward and one step back - always returning to the original starting position. while this might result in a frenzy of activity, it would result in a zero velocity. because the person always returns to the original position, the motion would never result in a change in position. since velocity is defined as the rate at which the position changes, this motion results in zero velocity. if a person in motion wishes to maximize their velocity, then that person must make every effort to maximize the amount that they are displaced from their original position. every step must go into moving that person further from where he or she started. for certain, the person should never change directions and begin to return to the starting position.

The particles of the gas inside the ball heats up, bouncing off each other and spreading farther apart.hope my answer has you : )
