anyone have any ideas on this problem? I tried 1, 2, 6, and 7, but that also did not work.

Im trying to work out a similar problem to this one. Does anyone know how to go about solving part B? I'm not sure how one would start the problem. I tried determing the probabilities of 5-0, 0-5, 4-1, 1-4, 3-2, and 2-3, and then used the ration of 0-5 to the sum, but that produced an incorrect...

Homework Statement In a fusion reaction, the nuclei of two atoms join to form a single atom of a different element. In such a reaction, a fraction of the rest energy of the original atoms is converted to kinetic energy of the reaction products. A fusion reaction that occurs in the Sun converts...

That was the problem. Thank you very much.

I am attempting to solve this problem. It seems simple enough but I seem to be getting the wrong answer. Here is what I have done: Uf=Ki 9e9*(1.6e-19)2 --------------------- = (.16)(1e6)(1.6e-19) r 2.304e-28 = 2.56e-14*r r=9.0e-15 Can...

Perhaps my questions were phrased poorly. If it is an elliptical orbit, which I should have specified, then the object would slow down as it moves away from the star or speed up as it approaches a point closer to the star, atleast that was my understanding. If it was slowing down, is it true...

An object orbits a star, both items comprise the system. I am looking for confirmation of a couple of concepts regarding orbits. As the object slows down, does the kinetic energy of the system decrease, and does the total energy of the system decrease? As the kinetic energy of the system...

If the comets are in the same orbit.

Given just the distances from the sun of two comets for example, and the speed of one of the objects, how could one relate these two objects in order to find the speed the other object is traveling at?

If you have two isotopes, would the speed of sound through the atom be larger in the heavier isotope or the lighter isotope, or would they be equal, and why?
