Image Lenses Position

AI Thread Summary

To calculate the position of the image formed by two identical diverging lenses with a focal length of -10 cm and a separation of 25 cm, the thin lens formula should be applied twice. First, determine the image position produced by the first lens using the formula 1/f = 1/do + 1/di, where do is the object distance (infinity, which simplifies calculations). The virtual image from the first lens acts as the object for the second lens, and its distance needs to be recalculated based on the separation between the lenses. The final position of the virtual image is found to be 7.7 cm from the second lens. This method effectively illustrates the step-by-step approach to solving the problem.

Are considered two identical diverging lenses, each one of focal distance -10cm and separated 25cm. which it is the position of the image of an object located in the infinite? The answer is: Virtual image and to 7,7 cm of the second lens. I need to know how to solve the problem, step by step.

To get help, show what you've done so far. (Hint: Use the thin lens formula-twice.)

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'

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...

Thread 'Explain this asphalt sheen'

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. And one more spoiler:
