Increasing the amplitude of a traveling wave with a period t will
a. increase the speed of the wave moving through the medium.
2. increase the speed of the individual particle in the medium.
3. not have an effect on either the wave speed or the particle speed.
4. change t, but how it changes will depend on the shape of the wave.
5. will decrease the period t.
6. will increase the period t.

Awind turbine is rotating counterclockwise at 0.5 rev/s and slows to a stop in 10 s. its blades are 20 m in length. (a) what is the angular acceleration of the turbine? (b) what is the centripetal acceleration of the tip of the blades at t=0s? (c) what is the magnitude and direction of the total linear acceleration of the tip of the blades at t=0s?

The earth exerts a gravitational force of 500 n on amy. what is amy’s mass in kg?

Two steel balls, each of mass m, are welded to a light rod of length l and negligible mass and are initially at rest on a smooth horizontal surface. a horizontal force of magnitude f is suddenly applied to the rod as shown. determine (a) the instantaneous acceleration a of the mass center g and (b) the corresponding rate at which the angular velocity of the assembly about g is changing with time.
