sam threw an object into his backyard pool. the object will float if
a. has more volume than water

b. is more dense than the water

c. has less volume than the water

d. is less dense than the water

Volume doesn't matter in this equation, as air will almost always float on water no matter the volume. So A and C are incorrect. The the object is more dense than water, it will sink because it has enough density to push through the water. But if it is less dense, then the water has enough force to hold it in place because the downward force of the object is less than the force of the water. The correct answer is D.
