Objective: SWBAT understand the relationship between density, volume, mass and the buoyant force.
Warm Up: An aluminum object has a mass of 27.0 kg and a de4nsity of 2.70 x 10^3 kg/cubic m. The object is attached to a string and immersed in a tank of water. Determine the a) volume of the object and b) the tension in the string when it is completely immersed.
