Air pressure Pressure

AI Thread Summary

Indoor pressure is generally similar to outdoor pressure, but there can be slight differences due to factors like ventilation and air-tightness of the building. In an air-tight room, the pressure can vary significantly from the outside, especially if air is removed or added. If indoor pressure is lower than outdoor pressure, it can lead to structural issues or air movement into the building. Conversely, higher indoor pressure can cause air to escape, affecting energy efficiency. Understanding these dynamics is crucial for building design and environmental control.

1. Is the pressure inside a building equal to the outside? Is there a very tiny difference?
What about air-tight room?

If the pressure was different, what do you think would happen? Have you tried crushing a juice pack by sucking some air out?

It would depend on how "open" the building was.

Thread 'Errors and significant figures'

I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...

Thread 'A cylinder connected to a hanging mass'

Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...

Thread 'Explain this asphalt sheen'

This problem is two parts. The first is to determine what effects are being provided by each of the elements - 1) the window panes; 2) the asphalt surface. My answer to that is The second part of the problem is exactly why you get this affect. And one more spoiler:
