An unknown object weights 17.0 N in air. When the object is suspended by a light cord and totally immersed in water, the tension in the cord is 11.0 N. Find the object’s volume and density?
1)A rock is suspended from a string in air. The tension in the string is 2.94N. The rock then is submerged in a liquid, and the tension in the string drops to 2.06 N. If the density of the rock is 2.55 g/cm^3 what is the density of the liquid? 2)When exposed to sunlight, a hole in a sheet of copper expands in diameter by 0.153% compared to its diameter at 68 F. What is the temperature of the copper...
