AI Thread Summary
To find the currents i1 and i2 in the circuit, apply Kirchhoff's law, which leads to the equation -1.5 + i1 + i2 = 0. Since there are two unknowns, an additional equation is necessary, which can be derived using Ohm's law or current dividers. The discussion suggests using KVL around a loop to establish a second equation, such as -1.5R + 100i1 + 150i2 = 0. Ultimately, the relationship between voltages across the resistors must be established to solve for the unknown currents.

Yes, but that is in the next chapter

Then you must have covered some other method(s). How about current dividers? KVL around a loop? Or, if you answered part (b) first and found the voltage ##v_o##, could you then find the currents?

Yes, KVL around a loop, but i don't know the current

-1.5 + i1 + i2 = 0
-1.5R + 100i1 + 150i2 = 0

Write the equation that shows: voltage across the 100Ω = voltage across the other pair
 

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'

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...
