Wave crests in a pond are separated by 0.2m . the period of these waves is 0.2 s . what is the speed at which these waves travel?

How is sound energy produced a. vibrating objects b. objects being heated c. temperature differences d. stationary objects

If a stone with an original velocity of 0 is falling from a ledgeand takes 8 seconds to hoybthe ground whays the final velocity of the stone

The particle p starts from rest at point a at time t = 0 and changes its speed thereafter at a constant rate of 2.8g as it follows the horizontal path shown. determine the magnitude and direction of its total acceleration (a) just before point b, (b) just after point b, and (c) as it passes point c. state your directions relative to the x-axis shown (ccw positive) and choose the angle with the smallest magnitude.
