Relation Shell Solid Solid sphere Sphere

AI Thread Summary

A shell can be conceptualized as a thin layer surrounding a solid sphere, with the sphere being made up of an infinite number of these shells. The gravitational effects of a solid sphere can be derived by integrating the contributions from these individual shells. Each shell contributes to the total mass and gravitational field of the sphere, allowing for the calculation of properties like gravitational force. Understanding this relationship is essential for solving problems related to gravitational fields and potential energy in physics. The discussion emphasizes the importance of integrating the effects of smaller shells to comprehend the behavior of a solid sphere.

A solid sphere can be thought of as composed of an arbitrarily large number of smaller shells...
How could you 'add up' the effects of many smaller shells, to construct a sphere?

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:
