AI Thread Summary

To calculate the number of revolutions a tire makes over a distance of 101,000 km, the circumference of the tire must first be determined using the formula C = 2πr, where the radius is 0.33 m. This results in a circumference of approximately 2.07 m. Dividing the total distance of 101,000,000 m by the tire's circumference gives the total number of revolutions, which is roughly 48,800,000. The discussion highlights the importance of correctly applying the formula and understanding the relationship between distance, circumference, and revolutions. Accurate calculations are essential for understanding tire wear and performance.

The warranty on a new tire says that an automobile can travel for a distance of 101000 km before the tire wears out. The radius of the tire is 0.33 m. How many revolutions does the tire make before wearing out ?

d=101000000m
Maybe I should try using C=2pi*r? and then multiply by the distance?

Not quite write. Try something more like C*n =d.

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:
