Document Summary
The force exerted by the mass is due to its weight. The angular frequency depends on the spring constant and mass k m. The period of a simple pendulum is given by. Since mass does not appear in the equation, the change of mass does not affect the period. When the mass is at its maximum amplitude, its velocity is zero. The angular frequency can be found from the period. The speed of a wave in a string is given by v. The tension (f) in the string is due to the suspended mass, N490 and is the mass per unit length of the string m. The time needed for the wave depends on the distance and the speed of the wave, t x v m8. In a transverse wave, the individual particles of the medium move perpendicularly to the direction of the wave"s travel.
