I'm still having problems on this second one, sure i can get the velocity, and then the time using the 12.2 km. However then how am I supposed to find the fraction of neutrons from this data, I'm still perplexed to say the least.
Hey guys, simple question about binding energy. I'm asked to find the average binding energy per nucleon of Magnesium-26. Now I thought that I would have to use: Binding E = (Zmp + Nmn - Ma) X 931.494 MeV/u. Where Z is the atomic #, N is the # of neutrons, mp, mn, and Ma are mass of proton...
Our school uses something called CAPA which is basically an online physics assignment. I put that answer that I got in and it said it was incorrect that's how I know I'm wrong, I have 2 more trys at it before I just lose the marks.
Your idea about using the thermal energy would be good...
Darn I don't understand what you mean still...
Wf = final angular velocity of the wheel
Wi = initial angular velocity of the wheel
I = moment of inertia of the wheel
I just did Work = change in KE = 1/2IWf^2 - 1/2IWi^2
Hey I'm new here I have a question that is bothering me, so here it is:
Q: A playground merry-go-round of radius R = 2.15 m has a moment of inertia of I = 214 kg·m2 and is rotating at 13.4 rev/min about a frictionless vertical axle. Facing the axle, a 20.4 kg child hops onto the merry-go-round...
