RE: SteemSTEM physics challenge #1 - Up!
That's a good first try, but that's not the entire story. First, could you please add enough text so that anyone, even without any physics background, could follow. Thanks in advance (the idea is to share with others the solving of the problem).
Next, and more important: you are making approximations. Please justify them.
this is just some estimate, the question above without weight mass
What I meant is that estimates are OK, as long as they are justified (quantitatively). Can you please justify them? Thanks in advance.
The picture above shows a toy balloon that lifts the house, so the question is how many balloons are needed to lift the house. We just assume energy or lift (number of balloons) per 1kg, thanks @lemounth
Sorry for being unclear, as said below. Let us assume real balloons and a real house :)
If we assume the original house and ballon, what thread or rope will we use? Balloon made of soft rubber and gell, if only we use a strong rope may be a balloon that will tear. i think this is impossible
You have different types of balloons and ropes. IT is up to you to chose the right ones :)
