1. A solid block is attached to a spring scale. When the block is suspended in air, the scale reads 20.0 N ; when it is completely immersed in water, the scale reads 16.9 N .
(a) Draw a free body diagram for the block when it is in the air
(b) Draw a free body diagram for the block when it is in the water
(c) What is the buoyant force experienced by the block?, show all work.
(d) What is the volume of the block?. Given the uncertainty of the scale reading is 0.01 g, what is the uncertainty in the volume?
(e) What is the density of the block?
