PHYSICS NEED HELP FAST
posted by ricki .
a 1.0kg beaker containgin 2.00kg of oil with a density of 916kg/m3 rests on a scale. a 2.0kg block of iron is suspended from a spring scale and completly submerged in the oil, find the euilibrium readings of both scales.density of iron 7860.
first the bouyancy supplied to the iron block:
bouyancy=volume*densityoil=2/7860 * 916
work that out.
then the scale above is supporting 2kg-bouyancy.
the scale below is supporting the beaker, the oil, and the bouyancy force.
