Homework Statement


What is the value of 3.0 coulobms per second in Amps?

The Attempt at a Solution


amps are coulombs per second, so its just 3 right? I just want to make sure this isn't some kind of trick. thanks for any input.
 
Physics news on Phys.org
Only trick is making it too simple :wink:
(Almost similar case with asking student to convert -40oF into Celcius. Just happens to work out that it's also -40, so poor student wastes the rest of the test trying to find his nonexistant error...)
Oh, yeah. Keep track of significant figures, also. Other than that, you're right on!
 
The book claims the answer is that all the magnitudes are the same because "the gravitational force on the penguin is the same". I'm having trouble understanding this. I thought the buoyant force was equal to the weight of the fluid displaced. Weight depends on mass which depends on density. Therefore, due to the differing densities the buoyant force will be different in each case? Is this incorrect?
