AI Thread Summary
The discussion focuses on the evaluation of the electric potential function v(x,y,z). Participants emphasize the importance of showing intermediate steps in problem-solving to identify errors more easily. One contributor notes that the first term appears reasonable but questions the exponent of the z factor. There is a suggestion to retain each term in its original form rather than combining them, as this clarifies the source of each term. Overall, the conversation highlights the need for detailed reasoning in mathematical solutions.

I would suggest you give us your reasoning and middle steps rater than just providing your final answer in your proposed solution. It will make it much more obvious where you go wrong if you do. I checked the first term only, which looks reasonable apart from the exponent of the z factor. I am guessing you are on the correct track but I really cannot tell if you do not give more details.
I would also keep each term as it is and not try to put it on a common denominator, it will make it more apparent where each term comes from.

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.
