A solid glass object weighs 10.192 N in air. It has a volume of4รƒย—10-4m3. Later, it is
completely immersed in ethyl alcohol at the end of a spring scale.The density of ethyl
alcohol is 790 kg/m3. The buoyant force due to air is negligible.The buoyant force due to ethyl alcohol is 3.0968 N.

a) What is the reading of the spring scale when the object iscompletely immersed in
ethyl alcohol?

b) Find the density of glass.

I am confused on how to set up this problem. The use of the springscale in the problem really confuses me. Thanks for your help!

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)
