The equation of a wave travelling in a rope is given by `y=10 sin (2.0 t-0.04x)` where y and x are expressed in cm and time t in second. Calculate the intensity of the wave if the density of the material of the rope is `1.3 xx 10^(3)kg//cm^3`.

Explanation

To calculate the intensity of the wave described by the equation \( y = 10 \sin(2.0 t - 0.04 x) \), we can follow these steps:

### Step 1: Identify the parameters from the wave equation
The wave equation is given as:
\[ y = 10 \sin(2.0 t - 0.04 x) \]

From this equation, we can identify:
- Amplitude \( A = 10 \) cm
