AI Thread Summary
A 6-foot tall person needs a mirror that is at least 3 feet tall to see their full body image. This requirement is based on the principle that the height of the mirror only needs to be half the person's height. The distance from the mirror also affects the perceived size of the reflection; standing further away makes the image smaller, allowing for a shorter mirror. Understanding these concepts clarifies why a shorter mirror suffices for full-body reflection. The discussion highlights the interplay between mirror height and viewing distance.

6-foot tall person stands in front of flat mirror. How tall must mirror be for this person to view his full body/image? <-Yeah, that's a question.

Problem is, this is like more-so of a conceptual question.

I do know the answer is 3 feet. That's what's so dang confusing... To see your full body/image... I thought 6 feet at first :-P
 
It will depend on how far away from the mirror you are standing. The further away you get, the smaller your 'image' gets and so the smaller the mirror can be.

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'

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...
