A ball of Styrofoam (ρ = 100 kg/m3) is totally submerged in water. The ball has a mass of 300.0 g (it could be a pretty big block).
What is the volume of the ball?
If a string holds the ball when it’s in the water, what’s the tension in the string?
Physics please help. -
.3kg=100kg/m^3 * V
solve for volume
volume=.3/100 m^3=.003 m^3
