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: ->->->->->->->->->->->-> :

400 grams or .4 kg

• What is the buoyant force on the ball?

answer/question/discussion: ->->->->->->->->->->->-> :

The buoyant force:

2.5 N = m * 9.8m/s^2

m = .255 kg or 255 grams

• What therefore must be its volume?

answer/question/discussion: ->->->->->->->->->->->-> :

255 cm^3

• What is its density?

answer/question/discussion: ->->->->->->->->->->->-> :

.4 kg
