Thanks for both the replies all the replies. I think I finally get it.

When a charge is applied to a conducting sphere and connected to another conducting sphere by an ideal thin wire (infinite distance apart), the potential at the surface of each sphere is the same. However, that means (for spheres of different radii) that the charge density on each sphere...

Picture The correct answer turned out to be 12.7 L/s. I get everything except for the use of the change in densities. Thanks for all your help, by the way, I appreciate it! To think of my 40k / year tuition and I need to find help online from a helpful stranger.

After confirming with a friend, I realized that I just had the conversion factor wrong. Their method worked, and apparently m^3/s * 1000 = L/s. Unfortunately, this leaves me no closer to understand why they used the two densities and not just the mercury density. With a lot of luck I might be...

Homework Statement Known/Given Water flows through a Venturi meter (mercury [density=13.6E3 kg/m^3] in the manometer). Pipe size: 10.0cm diameter Constriction size: 5.6cm diameter Height difference of mercury: 2.3cmUnknown - Flow Rate (L/s)Homework Equations Bernoulli's - P1 + (1/2)*d*V1^2 = P2...

I'm trying to do a lab writeup, and I'm going to include the uncertainty values as part of the data table. I was measuring distances with a meter stick with smallest divisions of 1mm, and estimated the error to be .05cm (.5mm - half the smallest division, as our TA told us was a good rule of...
