To find the depth below the surface of water at which the pressure is equal to twice the atmospheric pressure, we can follow these steps: ### Step 1: Understand the given values - Atmospheric pressure, \( P_{\text{atm}} = 10 \, \text{N/cm}^2 \) - Convert this to SI units (N/m² or Pascals): \[ P_{\text{atm}} = 10 \, \text{N/cm}^2 = 10 \times 10^4 \, \text{N/m}^2 = 10^5 \, \text{N/m}^2 \] ...
