Vector from origin and two points/please explain how to solve it

AI Thread Summary
To solve the problem, a vector A needs to be determined from the origin to a point on the line between points r1 and r2, at a distance xr from r1. The distance r is defined as the difference between r1 and r2. It is suggested that sketching the scenario can aid in understanding the problem better. The components of vector A should be expressed in terms of r, r1, r2, and xr. Clarifying these components will help in formulating the solution effectively.

Drawing, or sketching the problem is always beneficial...
I took the liberty of doing it for you;
O-is the origin in this case... try figuring it out now, it should run along more smoothly...

Thanks a lot! But I can not understand a question. What should I find? Components of vector A? Or?
 
Yes, you need to express A using what you've been given, i.e r, r1, r2, xr...
Keep trying,

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 '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...
