Two Identical Fish, Both at Sea Level, Float in Two

question 36

Multiple Choice

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?

• B) Fish A displaces a greater quantity of water than fish B.
• C) Fish B displaces a greater quantity of water than fish A.
