Passage 18: Question 2--

F_b=density_liquid*g*V
I answered C because since Y has a larger density than X, it exerted a larger force than X.

Passage 23: Question 1--

I cam down to B and D.
I answered B because:
P=F/A
Since the Area for 2 is smaller than the Area for 1, the Pressure for 2 is greater than the Pressure for 1.

Both answers I chose are wrong, and I can't seem to figure out WHY!

(1) F_b = F_w of the object for both fluids. This is true so long as the object floats and does not accelerate downward.
