An ore sample weighs 17.5 [N] in air. When the sample is suspended by a lightcord and totally immersed in water (water = 1000 [kg/m3]), the tension in the cord is 11.2 [N].a. What is the magnitude of the buoyant force acting on the sample? [2 pts.]b. What is the volume of the sample? [2 pts.]c. What is the density of the ore sample? [2 pts.]
