After a wave passes through a medium, particles in the medium:
a. are permanently displaced in the direction opposite to the direction of the wave
b. remain in the new location
c. are moved along with the wave
d. return to the original position

In an experiment, how can i change human errors? be specific.

Awater balloon launcher uses an elastic band with a spring constant of 115 n/m to use thee launcher you stretch thee band back with a balloon n it the water balloons have a mass of 1.3 kg a) if you stretch the band by 0.8 m, what elastic force will the band exert? b) with the band stretched 0.8 m, how much elastic potential energy is stored in the spring? c) if you release the band, it pushes forward. what is the kinetic energy of the balloon when it reaches the natural length of the band? d) what is the speed of the balloon when it reaches the natural length of the band?

The total amount of energy contained in an object
