65. The transverse wave propagates along an elastic cord with a speed υ = 10 m / s. The amplitude of the oscillations of the points column A = 5 cm, and the oscillation period T = 1 s. Record wave equation and determine: 1) the wavelength; 2) phase of oscillation, displacement, velocity and acceleration of a point located at the distance x1 = 9 m from the source of vibrations at time t1 = 2,5 s.
