Welcome to PHY 121 Blog Help. Here's how it works. For each homework question and lab report we will make a post, this will probably contain a few tips on what the problems are about and how to solve them. If you are stuck on something then instead of emailing us directly you should post a comment in reply to the relevant post. We will try to guide you through tough points and help you understand the problems and the concepts behind them.

Think why is mercury higher on the side of the box. Recall hydrostatic pressure in for liquid in equilibrium.

Did P = Patm + Density(Mercury)*g*(.1m) for height difference of 10 cm's... got 110000 and it's wrong?
Converted Patm to Pa of 101325, and used g for 9.8 and density of mercury of 13600 kg/m^2

try subtracting Density(Mercury)*g*(.1m) from Patm
Is pressure inside the box higher than atmospheric pressure? If yes what makes mercury to raise?
