Two identical fish, both at sea level, float in two identical aquariums with identical quantities of water. Fish A is in Alaska, so it weighs more than fish B at the equator, since g is larger at sea level in Alaska. Which statement is correct?
A. A comparison is impossible unless they are both floating at the same level.
B. Fish A displaces a greater quantity of water than fish B.
C. Fish B displaces a greater quantity of water than fish A.
D. They both displace the same quantity of water.
E. Fish A has a smaller acceleration than Fish B when equal horizontal forces are applied to each, because Fish A weighs more.
