Thanks for helping me clarify this!

Homework Statement Consider a ^3D_X where X=3/2 state. a) What are the possible values of S, L, J and J_z? Homework Equations Spectroscopic notation for this LS coupling is ^YL_J where Y=2S+1. J ranges from|L-S| to |L+S| The Attempt at a Solution Since L=2 and S must be equal to 1, how can...

Got it. Thank you! I was to narrow with my thinking, "dumbing" the problem down too much and didn't consider it would have to involve more thinking than just the 3 equations i gave. The fourth I consider was just some rubbish once I checked the dimensions. v_1t_1+x_1=100 was the last one...

Hello, I am currently by some reason struggling with this problem. I cannot seem to get the correct reasoning here. I would appreciate any help! 1. Homework Statement Ann and Lisa cross the 100 m finish line at the same time, 10.2 s after start. Both had constant acceleration until they...

Thank you very much for your informative reply! I will read more upon the subject of reference state regarding zero enthalpy so I'll hopefully get a full comprehension of this.

Hello! I was playing around with a problem and while I was doing it I noticed a similarity between Cv*T=h by using celsius and not Kelvin. So if I have a compressed liquid at say 50°C, looking up at a property table I find the hf to be 209.34 kJ/kg (the pressure is considered to be...

I've finally managed to get my hands on a manual for the operation of the machine, but the process described in the manual combined with the process you provided a description of "Bobbywhy" really helped me get a better and more clear understanding of the process. Thank you very much for your reply!

Hello! I am currently trying to figure out how a water recycling machine works (this machine http://www.floridawb.info/page45.html except I have the CW2 version). I am stumbling a bit on understanding the CFC system of this machine. I believe it has something to do with the cataclytic chamber...

Homework Statement A uniform, straight rod with mass M and length L can rotate about a horizontal axis A in a distance L/4 from the rods end. Vi can disregard friction. Gravity is 9.81 m/s^2. (drawing included at the bottom) 1) Find an expression for the moment of inertia of the rod at point...

Thank you guys very much. I ended up solving it by using the method described by HallsofIvy and got 108m vertically from the point of start. And yeah, it was just a typo voko :)

Ok, thanks. So call the walking length L. L is split into two legs, leg X and leg Y. Point T is the vertex of X and Y on the river. X=√(72²+T) and Y=√(8²+(120-T)²) L=X+Y L= √(72²+T) + √(8²+(120-T)²) Taking the derivative of L with respect to T, and letting the derivative of dL/dT = 0 yields...

Homework Statement You are standing on an open field 72,0 m away from a straight river. Your tent is 136 m away from you, while being only 8,0m away from the river (on the same side you are on). Before you go back to your tent, you would like to fill your water bottle in the river. What point...
