Homework Statement
A test tube standing vertically in a test tube rack contains 3.8 cm of oil, whose density is 0.81 g/cm3 and 6.4 cm of water. What is the gauge pressure on the bottom of the tube? The acceleration of gravity is 9.8 m/s2. Answer in units of Pa
Homework Equations
P1-Po=[tex]\rho[/tex]oilgh1+[tex]\rho[/tex]H2Ogh2
The Attempt at a Solution
P1-Po= (810 kg/m3)(9.80 kg m /s2)(0.038 m) + (1000 kg/m3)(9.80 kg m/s2)(0.064 m)
P1-Po= 929 Pa
Is the work and answer right? TIA
