A harmonic wave is traveling along a rope. The oscillator that generates the wave completes 49.0 vibrations in 20.8 s. A given crust of the wave travels 402cm along the rope in a time period of 14.9 s What is the wavelength?answer in units of m

Calculate the first and second velocities of the car with four washers attached to the pulley, using the formulas v1 = 0.25 m / t1 , and v2 = 0.25 m / (t2 – t1) where t1 and t2 are the average times the car took to reach the 0.25 and the 0.50 meter marks. record these velocities, to two decimal places, in table e.
