An emission spectrum can contain wavelengths produced when an electron goes from the third to the second leve. So could you see this like in the absorption spectrum? Why?
Hi, I have a couple of questions here I am having a little bit of difficulty with.
1) What is the wavelength of an X-ray that has a period of 1.30x10e-10s?
2) A certian EMR has a wavelength of 2.14x10e-5m in air. What is the wavelength is water(n = 1.33)?
I am not looking for the...
Hey all I was just wondering if anyone knows how to figure out these two questions.
1) The difference in potential between the cathode and the anode of a spark plug is 1.0x10^4V. What energy does an electron give up as it passes between the electrodes?
This one I am really pretty clueless...
Thanks =)
Thanks.
v2 = 2gh
v2 = 2(9.81)(9.0m)
v2= 176.58m/s
v = 13.3m/s
v2 = 2gh
v2 = 2(9.81)(0.25m)
v2 = 4.905
v = 2.2m/s
Is what I ended up with. Least I am on the right track I hope. =)
Edit: Also going to look up what you suggested "conservative field"
Hello all, just started taking physics 30, or pyhsics 12 and need some help with two questions. Any help is appreciated.
1. A frictionless incline with a vertical rise of 4.0m and a slope of 9.0m is used to slide a box from the 4.0m height. If the box starts from rest at the top of the...
