Question

A wave pulse on a string moves a distance of 16 m in 0.4 s. Find the speed of the pulse.

Answer 1

Step 1:Given data

1. Distance covered by the wave pulse(d) = 16 m
2. Time taken (t) = 0.4 seconds

Step 2:To find the speed of the pulse:

1. We know the formula that,
2. Speed = $\frac{\mathbf{D}\mathbf{i}\mathbf{s}\mathbf{t}\mathbf{a}\mathbf{n}\mathbf{c}\mathbf{e}}{\mathbf{t}\mathbf{i}\mathbf{m}\mathbf{e}}$
3. Speed = $\frac{16}{0.4}$ = 40 m/sec

The speed of the pulse is 40 m/sec.
