I'm at wits end. I hate WileyPlus. Part A, B and C are correct. I cannot figure out what Part D is -- all of the answers I am getting are wrong.
Double Slit Diffraction:Finding Greatest Angle for Minimum
- Thread starter Zach Hughes
- Start date
AI Thread Summary
The discussion centers on frustration with the WileyPlus platform while attempting to solve a problem related to double slit diffraction. Parts A, B, and C of the homework have been completed correctly, but Part D remains unresolved despite multiple attempts. The key question raised is about the condition for achieving a minimum in the diffraction pattern. Participants express a desire for clarity on the mathematical requirements needed to solve Part D. The conversation highlights the challenges students face with specific homework problems in physics.

What is the condition for a minimum?
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...
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
$$T + f_f - N_w = Ma$$

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.
