# upthrust watch

1. i believe i wrote it in an earlier post with the density with correct units. i hadnt but owel here it is :P.

(((4/3)x(pi))x(0.95x10^-2)^3)x0.92x10^3x9.8 = 0.03237973784

This is correct.

Weight is greater than this. The ball should sink, experiment's consistent with theory.
3. the weight isnt greater though. the weight is 0.02798 and U is 0.03238

Weight is (mass)x(gravitational acceleration). 0.028 kg is mass, not weight.
5. thank you for the helped i figured that out later on :P. tired error i guess :L.can you help me again?
what would my units be now for W-U=F and then F/6(pi)rv= coeffecient of viscosity. i need the units for the coefficient manly . thanks

Forces are in newtons, . The units of coefficient of viscosity is (because ).
