The speed of longitudinal mechanical wave in a material is 4300 m/s. young's modulus of the material is `15xx10^(9)N//m^(2)`. What is the density of the material?

Explanation

To find the density of the material given the speed of a longitudinal mechanical wave and Young's modulus, we can use the relationship between these quantities. Here’s a step-by-step solution:

### Step 1: Write down the given values
- Speed of the longitudinal wave (v) = 4300 m/s
- Young's modulus (Y) = 15 × 10^9 N/m²

### Step 2: Use the formula relating speed, Young's modulus, and density
The formula that relates the speed of a wave in a medium to its Young's modulus and density is given by:
