Density Mass Rectangle

AI Thread Summary

The discussion focuses on calculating the total mass of a rectangle with a variable surface density defined by σ(x,y)=12 kg/m²+2 kg/m⁴(x²+y²). The rectangle measures 1.00 m in height and 1.20 m in length, with the origin at the lower left corner. Participants are encouraged to share their attempts and specific challenges to receive targeted assistance. The conversation emphasizes the importance of understanding the integration process needed to find the total mass. Engaging with others can clarify the steps involved in solving this problem.

1) Homework Statement [/b]

The surface density of a rectangle varies as:
σ(x,y)=12 kg/m2+2 kg/m4(x2+y2)
The origin is located at the lower left corner of the rectangle, at point ``A.'' The rectangle has a height h=1.00 m and a length l=1.20 m. What is the total mass of this object?

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:
