for our lab, we had to fill a semi-circle plastic dish (with a scratch on one side) with water and find the index of refraction of water by putting a pin on one side of the dish, looking through the water, and put a pin on the other side of the dish to line up with the first ...

A frog in a hemispherical pod just floats without sinking into a pond with density 1.35 g/cm^3. If the pod has radius 6 cm and negligible mass, what is the mass of the frog? wouldn't one need the thickness of the pad? And what has the density given? The pond water, or the frog...

The tank shown is full of water. Given that water weighs 62.5 lb/ft3, find the work required to pump the water out of the tank. The tank shown is a hemisphere with r = 5 ft. The water is to be pumped out at the top. First I solved for ri, ri / (5 - xi) = 5 / 5 ri = 5 - xi Vi...

In general when instructions are to let a solution cool to room temp would it be incorrect to put the bottle containing the solution into a cold water bath so it could cool faster? Would it affect the solution in an adverse way? or does it depend on what you are cooling? ...

Is this stump the teacher? There are standard distances for flanged elbows measured from center line, and in fact, the distances vary by type of elbow and thickness (pressure rating). Of course, you know that.
