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: ->->->->->->->->->->->-> :
.4*9.8=3.92N
This is the weight of the ball. Weight is the force exerted by gravity.
3.92+2.5=6.42N
this doesn't help
6.42=m * 9.8
655g
nothing here has a mass of 6.42 N

What is the buoyant force on the ball?
answer/question/discussion: ->->->->->->->->->->->-> :
6.42N

What therefore must be its volume?
answer/question/discussion: ->->->->->->->->->->->-> :
3.92N

What is its density?
answer/question/discussion: ->->->->->->->->->->->-> :
3.92N

This will be easy to fix, but you need to have the right picture so you don't make a mistake of this nature on the test.
