AI Thread Summary
A fully inflated tire has a slightly greater mass than a punctured or uninflated tire due to the air inside it. The added mass comes from the air, which contributes to the overall weight but is minimal compared to the tire's mass. While the pressure in a fully inflated tire is higher, the difference in mass is not significant. Therefore, the mass difference is primarily due to the air, which has a low density. Overall, the increase in mass from inflation is negligible.

Homework Statement


Just a quick question: does a fully inflated tyre have the same mass as a tyre that is punctured or uninflated?


Homework Equations





The Attempt at a Solution


The one that is fully inflated will have a greater pressure but I am not sure what this will mean in terms of the mass...

No, but not much more. The pressure is, of course, because of air in the tire. The fully inflated tire has more air inside it and so has the mass of that air added to the mass of the tire itself. Since air does not have a great deal of mass compared to the tire, the increase in mass is not very much.
 

Thread 'Rolling without slipping on a curved surface'

Kindly see the attached pdf. My attempt to solve it, is in it. I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction. I'm not able to figure out, why my solution is wrong, if it is wrong .

Thread 'Struggling to understand the concept of this question (ice cube in water optics question)'

TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...
