Question

An ore sample weighs 15.60N in air. When the sample is suspended by a light cord and totally immersed in water, the tension in the cord is 11.90N .

Part A

Find the total volume of the sample.

Part B

Find the density of the sample.

Answer 1

Answer #1

Part A Volume ofthe sample- Forces on the ore sample ma wherew- mg calculate F 15.60N-11.90N F-3.70N Volume. 3.70N 1000kg/m3 x(9.8m/s) SampE

Part B Density ofthe sample- Weight of the sample-15.60N 15.60N 98m/s m 1.591kg m= 1.591kg 3.77x 10 ρ= 4.22× 103 kg/m 3
