Here is what i'm doing!
Yellow: 1.492sin(30) = 1.000293sinθ
Green: 1.493sin(30) = 1.000293sinθ
When I do the calculations i am not getting the correct. The answer is suppose to be 0.043 degrees and 1.33 m. Where do you think I am messing up the calculations?
(a) A narrow beam of light containing yellow (660nm) and green (550nm) wavelengths goes from polystyrene to air, striking the surface at a 30 degree incident angle. What is the angle between the colors when they emerge? (b) How far would they have to travel to be separated by 1.00 mm?

I'm not sure that is the correct number i got for K, i have so many numbers on my paper everything is mixed together. I took the period given which was 1.5 divided by 2 pie 1.5/2pie = .239. Then i squared to get rid of the square root. Which gave me .239 = m/k. Then multiplied by k and divided.
I can't seem to get the right answer, where is my mistake?
A 90 kg skydiver hanging from a parachute bounces up and down with a period of 1.5 seconds. What is the new period of oscillation when a second skydiver, whose mass is 60 kg, hangs from the legs of the first?

I'm sorry, but I guess I am not understanding about how I get the information from the graph. Since E and r are unknown constants; does that mean that I could leave them out of the equation and just have V = I? Or am i making it harder than it really is?
Is this close? 2V = E - (5 A)r
I know that the internal resistance of a voltage source affects the output voltage when a current flows. I was thinking that I would use the equation V = E - Ir...but I seem to get a different answer each time I use it. I also know that V = IR.
Im my view of this problem I do not have enough...
Hello everyone!
I have a question and any help would be appreciated!
(a) What is the internal resistance of a voltage source if its terminal voltage drops by 2.00 V when the current supplied increases by 5.00 A?
(b) Can the emf of the voltage source be found with the information supplied?
