oh so it should be sqrt (3g/L) right?

We are supposed to use the bulk modulus from our textbook, and that one is 0.2*10^10. Anything else would give a wrong answer in the system. So with this bulk modulus, is 0.655L right?

Ok I made potential energy = rotational energy so i get: Ug = Krot MgL = 1/2 (1/3ML^2)w^2 GL = 1/6 (L^2)(w^2) sqrt(6g/L) = w so I put the answer as sqrt (6g/L) on the online system and its wrong, but I get this message: "Your answer either contains an incorrect numerical multiplier...

Yeah its kpa, so in the formula I should use 1 000 000pa and I get 6.55*10^-4 m^3 which will be 0.655L...is that right?

Homework Statement A cylindrical steel pressure vessel with volume 1.31 m^3 is to be tested. The vessel is entirely filled with water, then a piston at one end of the cylinder is pushed in until the pressure inside the vessel has increased by 1000 kPa. Suddenly, a safety plug on the top...
