AI Thread Summary
Vector notation in physics can be confusing, especially when it comes to directional angles. The notation "N 20 degrees E" indicates a direction that is 20 degrees east of north. This contrasts with the more familiar "20 degrees north of east," which would be written differently. Understanding this notation is crucial for accurately interpreting vector directions in physics problems. Clarity in these terms helps in effectively solving vector-related homework.

Ok, I am trying to help my friend with her physics homework and she is doing vectors right now. What I can't figure out is how they have the vectors written. They have it for example, N 20degrees E . What does that mean? I am use to doing them so many degrees north of east or east of north. So does the one above mean 20 degrees north of east, or 20 degrees east of north? Thanks.

East of North, that's the notation used in surveying :smile:
 
Thread 'Question about pressure of a liquid'
I am looking at pressure in liquids and I am testing my idea. The vertical tube is 100m, the contraption is filled with water. The vertical tube is very thin(maybe 1mm^2 cross section). The area of the base is ~100m^2. Will he top half be launched in the air if suddenly it cracked?- assuming its light enough. I want to test my idea that if I had a thin long ruber tube that I lifted up, then the pressure at "red lines" will be high and that the $force = pressure * area$ would be massive...
