1. The problem statement, all variables and given/known data On earth a certain apparatus can safely dive to a depth of 275m in a freshwater lake. This limitation is due to the external guage pressure on the apparatus. If this device were to be used in a lake on Mars, where the acceleration due to gravity is 3.70m/s^2 but the denisty of water is essentially the same as on earth, the greatest depth to which it could safely dive is closest to 1930m 728m 169m 448m 104m 2. Relevant equations p=p0+dgh 3. The attempt at a solution I calculated the pressure of the earth dive to be 1.04*10^5pa using p=1.013*10^5+9.81*1*275. I know the g value for mars will be different and I think the atmospheric pressure on mars is different but is there a way to calculate the atm pressure of mars? Or am I to solve the problem without using either atmospheric pressures?
