Homework Help Overview

The problem involves two identical balloons filled with air at a pressure greater than atmospheric pressure, suspended on a stick to maintain horizontal balance. The question posed is whether puncturing one balloon disrupts this balance.

Discussion Character

  • Exploratory, Conceptual clarification

Approaches and Questions Raised

  • Participants discuss the implications of puncturing one balloon, with some asserting that it will upset the balance due to the change in weight. Others express uncertainty about the simplicity of the situation and whether there are additional factors to consider.

Discussion Status

There is ongoing exploration of the effects of puncturing one balloon on the balance of the stick. Some participants have offered straightforward reasoning regarding the forces at play, while others are questioning if there is more complexity involved.

Contextual Notes

Participants have noted that both balloons exert downward force on the stick, and the discussion revolves around the consequences of one balloon ceasing to exert that force. There is a lack of consensus on whether further considerations are necessary.

Homework Statement


Two identical balloons are of the same volume are pumped up with air to more than atmospheric pressure and suspended on the two ends of a stick so the stick is horizontally balanced. If one of the balloons is punctured is the balance of the stick upset?

Homework Equations





The Attempt at a Solution


I say yes. But I don't know why.

If the contents of the two balloons have more than atmospheric pressure then the balloons are heavier than air. So?
 
So, if the balloon on the left is popped then the stick will sag towards the right, or the direction of the balloon that is left. Is it that simple? I thought there might be something I was missing?

Yes, both balloons are pulling down on the stick. If you pop one, it will stop pulling down. Simple as that.
 
Thanks.
