the interpretation of the plus sign on the right
hand side
Distinguish between the interpretation given
to A for (i) longitudinal waves and (ii)
transverse waves calculate the end of wave
when x = 0.02m and T = 8.0 x 10s 2. What is
the phase difference between two points 2.5m
apart?​

Aplayground slide is 8.80 ft long and makes an angle of 25.0° with the horizontal. a 63.0-kg child, initially at the top, slides all the way down to the bottom of the slide. (a) choosing the bottom of the slide as the reference configuration, what is the system's potential energy when the child is at the top and at the bottom of the slide? what is the change in potential energy as the child slides from the top to the bottom of the slide? (include the sign of the value in your answer.)
