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. K.C.S.E Physics Q & A - MODEL 2013PP1QN04
​An object of weight 20 N attached at the end of a spring causes an extension of 0.5 cm on the spring.
(a) Determine the spring constant of the spring. (b) Determine the weight of an object that would cause an extension of 0.86 cm when attached at the end of the same spring.
