A student performs an experiment to determine the density of an unknown metal cylinder, density of cork, and the specific gravity of kerosene. The student weighs the metal cylinder in air and records it to be 0.98 N. When the cylinder is completely submerged in water it weighs 0.823 N and weighs 0.854 N when completely submerged in kerosene. a. What is the density of the unknown metal cylinder in kg/m? b. Compute the experimental value of the specific gravity of kerosene. c. A piece of cork has a mass of 0.025 kg in air. When it is fastened to a sinker and 1. the sinker alone immersed in water, the combined weight is 1.960 N. When both sinker and cork are immersed in water, they weigh 0.735 N. What is the density of the cork?
