Concave mirror producing an image 3 times larger than the object

AI Thread Summary
To produce an upright virtual image three times larger than the object using a concave mirror with a radius of curvature of 0.5 m, the object must be placed at a specific distance from the mirror. The discussion emphasizes the importance of showing work or prior attempts to solve the problem to receive effective help. Participants express frustration over the lack of initial effort in problem-solving. Clarification is sought on the meaning of "T.T," indicating a need for better communication. Understanding the principles of concave mirrors and magnification is crucial for solving this type of optics problem.

A concave mirror has a radius of curvature of 0.5 m. At what position should and object be placed to produce an upright virtual image that is 3.0 times as large as the object?
I have just no clue for this question,, but I have to understand it T.T
can any1 help me please>..

any one ? please.. T.T
 
That's rather impatient, waiting only 5 minutes! And you haven't even shown us any work!

What sort of thing have you done in class? Have you done any questions like this, or are there any examples in your book, or class notes on this? You need to show some work before we can help you.

Oh, and what does T.T mean?
 
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 'Struggling to make relation between elastic force and height'
Hello guys this is what I tried so far. I used the UTS to calculate the force it needs when the rope tears. My idea was to make a relationship/ function that would give me the force depending on height. Yeah i couldnt find a way to solve it. I also thought about how I could use hooks law (how it was given to me in my script) with the thought of instead of having two part of a rope id have one singular rope from the middle to the top where I could find the difference in height. But the...
