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: ->->->->->->->->->->->-> :
m = 400g = .4kg
.4kg * 9.8 m/s^2 = 3.92 N
#$&*
• What is the buoyant force on the ball?
answer/question/discussion: ->->->->->->->->->->->-> :
-3.92N + 2.5N = 1.42
Buoyant force = 1.42N
#$&*
• What therefore must be its volume?
answer/question/discussion: ->->->->->->->->->->->-> :
1000kg/m^3 * 9.8m/s^2 = 9800N/m^2
1.42N / 9800N/m^2 = .000145m^2

• What is its density?
answer/question/discussion: ->->->->->->->->->->->-> :
mass / volume = 400g / 145cm^3 = 2.8g/cm^3
