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?
400g / 2.5N=160g
answer/question/discussion: ->->->->->->->->->->->-> :
• What is the buoyant force on the ball?
400g * 2.5N=1000g
answer/question/discussion: ->->->->->->->->->->->-> :
• What therefore must be its volume?
1000g +160g=1160g
answer/question/discussion: ->->->->->->->->->->->-> :
• What is its density?
1000g-160g=840g
