Question 2
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 comparison is impossible unless they are both floating at the same level.
◦
Fish A displaces a greater quantity of water than fish B.
◦
Fish B displaces a greater quantity of water than fish A.
◦
They both displace the same quantity of water.
◦
Fish A has a smaller acceleration than Fish B when equal horizontal forces are applied to each, because Fish A weighs more.
