Answer 1

Answer:

which subject is this of i do not think this a question you should be asking here

Answer 2

Wave number, $k=\pi$

Explanation:

Given that,

A wave is represented by the equation,

$y=0.1\ sin(100\pi t-kx)$

The velocity of wave, v = 100 m/s

We need to find the wave number of the wave. The general equation of the wave is given by :

$y=A\ sin(\omega t-kx)$

We know that the velocity of a wave is given by :

$v=\dfrac{\omega}{k}$

k is the wave number

$k=\dfrac{\omega}{v}$

$k=\dfrac{100\pi}{100}$

$k=\pi$

Hence, this is the required solution.
