K.C.S.E Physics Q & A - MODEL 2013PP1QN05
State two measurements you would take in an experiment to determine the upthrust of an object which is immersed in a fluid.
State how the measurements in question (5) are used to determine the upthrust of the object.
answer
5. Weight of object in air
Weight of object when fully immersed in fluids 6. Upthrust = weight in air - weight of object in fluid. |
