Question

Help please

Archimedes Principle states that an object will float if the weight of the water it displaces is equal or greater than the weight of the object. Weight is multiplied by the due to and mass is multiplied by So after equating the two weights, the constants of and divide out. In practice, this means an object will float if itsis equal to or than the of the Sources of Error A Vernier Caliper good to :0.02 mm was used repeatedly to measure the diameter of a rubber ball. The diameter was measured from one measurement to the next due to times. This diameter varied error. The measurement of the ball's mass also exhibited error in However, the error in the was compared to the error in the Since the number of diameter measurements was small, the uation for the standard deviation used n-1 instead of n.

Answer 1

(a)

Weight is mass multiplies by acceleration due to gravity and mass is density multiplied by the volume.

So, after equating the two weights, the constants of acceleration and volume divide out . In practice, this means an object will

float if its density is equal to or less than the density of the fluid .
