The distance between two successive maxima of a certain transverse wave is 1.56 m. Suppose a maximum passes some point at t = 0, and eight more crests, or maxima, pass that given point along the direction of travel in the next 15.8 s. Calculate the wave speed. Answer in units of m/s.

the answer would be   dignified - apex

the motion of a pendulum is a classic example of mechanical energy conservation. a pendulum consists of a mass (known as a bob ) attached by a string to a pivot point. as the pendulum moves it sweeps out a circular arc, moving back and forth in a periodic fashion.
