An apple has a density of 641 kg/m3. water has a
density of 1000 kg/m3. what would happen if an apple
were placed in a tub of water?
o
a. the apple would sink to the bottom
o b. the apple would float but be completely
submerged in the water.
o c. the apple would float on top of the water with
no part of it submerged.
o d. the apple would float partially submerged in the
water

D

Explanation:

Since the apple is 641kg/m3 and water is 1000kg/m3 then the apple will float. Light materials float on top of the water similar to how oil is always on top of the water layer. Since the two are close so the apple will partially float
