A piece of aluminum has a density 2.7 gm/cm^3 and mass 775 g. The aluminum is submerged in a container of oil (oil's density= 0.65 gm/cm^3). How much oil does the metal displace?

A wooden ball with a weight of 16.0 N hangs from a string tied to aspring scale. When the ball is at rest, exactly 50% submerged inwater, the spring scale reads 3.00 N. For this problem, we will usea density of water of 1000 kg/m3, and we will use g = 10.0m/s2.

(a) If the ball was only 30.0% submerged in water instead, whatwould the spring scale read? (N)

(b) Determine the density of the ball. (kg/m3)

(c) Determine the volume of the ball. (m3)
