Why do electrons in hydrogen atoms emit infrared light when they make transitions to the n=3 energy level and uv light when they make transitions to the n=1 level? Does this have to do with wavelengths?

How would I figure out the horiz. distance if I have the velocity and the vertical distance? I also have the acceleration. What formula could I use?

Would the answer to this question be total energy and momentum for both one dimensional and two dimensional collisions: State the quantities conserved in one dimensional and two dimensional collisions.
Religion
MMMmmm...Kinda. It's the place you go to before Heaven and that is where your are cleansed or purged from the sins that you committed during your lifetime. That is why the priests come to say the last rites, to confess your sin so you won't have to spend as much time i...

State the quantities that are conserved in one-d and two-d collisions. Give an example of each type of collision. I looked in my textbook and all i could come up with was that momentum was conserved for both?

How do you figure out if a collision is elastics or inelastic, when it is dropped and then bounces? Do you figure out the velocity and then put that in the Ek formula?
Math 30 Pure
9x^2+16y^2+64y+28=0 I am supposed to convert this to standard form, but my answer doesn't make sense. One part was 9x^2/92...does that sound right?
