AI Thread Summary
To solve the equation P = (0.4887 psi/*c)T + 13.80 psi for temperature T, first isolate T by rearranging the equation. Subtract 13.80 psi from both sides to get P - 13.80 psi = (0.4887 psi/*c)T. Next, divide both sides by 0.4887 psi/*c to solve for T. The correct formula for temperature is T = (P - 13.80 psi) / (0.4887 psi/*c). This method ensures that T is properly isolated and calculated.

to solve for temperature would i divide p like this?
T= 0.4887psi/*c + 13.80psi/P
?

I know it's a simple problem, i just want to make sure I'm doing it correctly?

Nooo …

always start by shoving everything around so that T is the only thing on one side:

P - 13.80 psi = (0.4887 psi/*c)T

and then … ? :smile:
 
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...
