AI Thread Summary
To determine the image distance for a convex mirror, the formula used is 1/s + 1/s' = 1/f, where s is the object distance, s' is the image distance, and f is the focal length. In this case, the object is 32.7 cm from the mirror, and the focal length is -10.8 cm. By substituting these values into the equation, the image distance can be calculated. The negative focal length indicates that the mirror is convex, which affects the sign of the image distance. Proper application of the formula will yield the correct image distance.

Object-image relation:

1/s + 1/s' = 1/f

where

s = object distance
s' = image distance
f = focal length
 
Thank you!

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 'Trying to understand the logic behind adding vectors with an angle between them'

My initial calculation was to subtract V1 from V2 to show that from the perspective of the second aircraft the first one is -300km/h. So i checked with ChatGPT and it said I cant just subtract them because I have an angle between them. So I dont understand the reasoning of it. Like why should a velocity be dependent on an angle? I was thinking about how it would look like if the planes where parallel to each other, and then how it look like if one is turning away and I dont see it. Since...
