Check the accuracy of relation `P=puv^(-3)` P is linear momontum, p is density, u si velocity, v is frequency.

Explanation

To check the accuracy of the relation \( P = \rho u v^{-3} \), where \( P \) is linear momentum, \( \rho \) is density, \( u \) is velocity, and \( v \) is frequency, we will analyze the dimensions of both sides of the equation.

### Step-by-step Solution:

1. **Identify the Left-Hand Side (LHS)**:
- The left-hand side is linear momentum \( P \).
- The dimension of linear momentum is given by the product of mass and velocity.
- Therefore, the dimension of \( P \) is:
