`2.5 m//s`

B

`5 m//s`

C

`40 m//s`

D

`4 m//s`

Text Solution

Verified by Experts

The correct Answer is:
B
Frequency of wave ` = 1//4 Hz`.
Wavelength of wave , `lambda = 2 xx 10 = 20 m`
Velocity of wave `f lambda = 5 m//s`

Two small boats are 10m apart on a lake. Each pops up and down with a period of 4.0 seconds due to wave motion on the surface of water. When one boat is at its highest point, the other boat is its lowest point. Both boats are always within a single cycle of the waves. The speed of the waves is:

A simple harmonic oscillator at the point x=0 genrates a wave on a rope. The oscillator operates at a frequency of 40.0 Hz and with an amplitude of 3.00 cm. the rope has a linear mass density of 50.0 g//m and is strectches with a tension of 5.00 N. (a) determine the speed of the wave. (b) find the wavelength. (c ) write the wave function y(x,t) for the wave, Assume that the oscillator has its maximum upward displacement at time t=0. (d) find the maximum transverse acceleration at time t=0. (d) find the maximum transverse of points on the rope. (e) in the discussion of transverse waves in this chapter, the force of gravity was ignored. is that a reasonable assumption for this wave? explain.

A cork floating on the pond water executes a simple harmonic motion, moving up and down over a range of 4 cm. The time period of the motion is 1 s. at t=0 , the cork is at its lowest position of oscillation, the position and velocity of the cork at t=10.5s , would be

A projectile is thrown from a point O on the ground at an angle 45^0 from the vertical and with a speed 5 sqrt(2) m/s . The projectile at highest point of its tracjectory splits into two equal parts. One part falls vertically down to the ground 0.5s after the splitting. The other part t seconds after the splitting falls to the ground at a distance x meters from the point O. The acceleration due to gravity g = 10 m/s^2 . The value of t is
