Magnification of an image - How does the image look like?

AI Thread Summary
A magnification of -3.5 indicates that the image is virtual and inverted, as the negative sign denotes an inverted image. The magnitude of the magnification suggests that the image is larger than the object, specifically 3.5 times its size. Participants in the discussion are seeking clarification on these concepts and where to find more information. The Wikipedia link provided leads to the lens formula, which is relevant for understanding image formation. Understanding these principles is crucial for analyzing the nature of images produced by lenses.

It would seem that they are interested in knowing if the image is real or imaginary and if it's larger or smaller than the object in question.

Thread 'Voltmeter readings for this circuit with switches'

TL;DR Summary: I would like to know the voltmeter readings on the two resistors separately in the picture in the following cases , When one of the keys is closed When both of them are opened (Knowing that the battery has negligible internal resistance) My thoughts for the first case , one of them must be 12 volt while the other is 0 The second case we'll I think both voltmeter readings should be 12 volt since they are both parallel to the battery and they involve the key within what the...

Thread 'Correct statement about a reservoir with an outlet pipe'

The answer to this question is statements (ii) and (iv) are correct. (i) This is FALSE because the speed of water in the tap is greater than speed at the water surface (ii) I don't even understand this statement. What does the "seal" part have to do with water flowing out? Won't the water still flow out through the tap until the tank is empty whether the reservoir is sealed or not? (iii) In my opinion, this statement would be correct. Increasing the gravitational potential energy of the...
