Two waves are smultaneously passing through a string. The equation of the waves are given by
`y_1=A_1sink(x-vt)`
and `y_2=A_2sink(x=vt+x_0)`
where the wave number `k=6.28 cm^-1 and x_0=o1.50c. The ampitudes of `A_1=5.0mm and A_2=4.0mm. find the phase difference between the waves and the amplitude of the resulting wave.

Explanation

To find the phase difference between the two waves and the amplitude of the resulting wave, we can follow these steps:

### Step 1: Identify the phase of each wave
The equations of the two waves are given as:
- \( y_1 = A_1 \sin(kx - vt) \)
- \( y_2 = A_2 \sin(kx - vt + x_0) \)

From these equations, we can identify the phases:
