Question 1
To the nearest percent, what fraction of an iceberg is submerged? (ρice = 917 kg/m3, ρsea = 1.03 × 103 kg/m3.)
◦ 95%
◦ 93%
◦ 91%
◦ 89%
◦ 77%
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.
Answer 1
89%
Answer 2
They both displace the same quantity of water.
