Question regarding electronics (operation amplifier)

AI Thread Summary
The discussion centers on a question about an operational amplifier circuit, specifically regarding the connection of two oval black dots in a diagram. The user seeks clarification on whether the requirement for signal 1 to have twice the amplitude of another signal contradicts the need for signal 1 to be amplified ten times at the output. The user confirms that the two dots are connected and that the diagram aligns with the book's illustration. The inquiry highlights potential confusion in the specifications of the signals and their amplification. Clarification on these points is essential for understanding the circuit's intended operation.

Questoin are the two oval black dots connected?

edit:
It is required that the output should consist of signal 1 having twice the amplitude of signal .Also signal 1 is to be amplified 10 times at the output.
Don’t these two sentences contradict each other?

The two oval black dots is connected among themselves and I draw the diagram same as in the book.Yes,the two sentences followed one after another.
 

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...
