1. The problem statement, all variables and given/known data a research submarine has a 20 cm diameter window 8 cm think. the manufacturer says the window van withstand forces up to 1x106N. What is the submarine's maximum safe depth? 2. Relevant equations p = po + [tex]\rho[/tex]gd 3. The attempt at a solution p = F/A = 1X106 / 0.03 = 3.2x107 Pa so now do i use p = po + [tex]\rho[/tex]gd ?? but if i do what would be my [tex]\rho[/tex]? [tex]\rho[/tex] = m/v = m/[tex]\pi[/tex]r2h how would i find mass? thanks in advance for help!
