A ball of mass 400 grams is immersed in water. The ball is suspended in the water by a rubber band chain which exerts a tension force of 2.5 Newtons on the ball.
• What is the weight of the ball?
answer/question/discussion: ->->->->->->->->->->->-> :
.4kg*9.8m/s^2=-3.92N
#$&*
• What is the buoyant force on the ball?
answer/question/discussion: ->->->->->->->->->->->-> :
-3.92N+2.5N+Fb=0
Fb=1.42N
#$&*
• What therefore must be its volume?
answer/question/discussion: ->->->->->->->->->->->-> :
1.42N=m*9.8m/s=0.143kg=143g
Water=1g/cm3=143cm^3 volume of sphere
#$&*
• What is its density?
answer/question/discussion: ->->->->->->->->->->->-> :
400g/143cm^3=2.8g/cm^3
