I think i solved the (a), but i can't calculate the integral because the function is to complex.

check your work..., as I work thru this, I am getting something different, be careful with completing the square

So far so good...check your exponential factor

Thread 'Magnitude of buoyant force in fluids of different densities'

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?
