A certain `120 Hz` wave on a string has an amplitude of `0.160 mm`. How much energy exits in an`80 g` length of the string?

Explanation

To find the energy contained in an 80 g length of a string with a wave of frequency 120 Hz and amplitude 0.160 mm, we can follow these steps:

### Step 1: Convert Units
Convert the given amplitude from millimeters to meters and the mass from grams to kilograms.
- Amplitude \( A = 0.160 \, \text{mm} = 0.160 \times 10^{-3} \, \text{m} = 0.000160 \, \text{m} \)
- Mass \( m = 80 \, \text{g} = 80 \times 10^{-3} \, \text{kg} = 0.080 \, \text{kg} \)

### Step 2: Calculate the Linear Density (Mass per Unit Length)
