You are right, using the rules you've learned about infinity limits will get us ((1/n)/(1+(1/n^2))) and the limit of that as n approaches infinity is 0.

Homework Statement lim of (sin(x)/(x+sin(x)) as x approaches 0 Homework Equations none The Attempt at a Solution I tried using trigonometric identites to figure it out but I can't do it, and when I looked up help for it I only found solutions that utilize the l'hospital's rule. I...

It doesn't outright say what the nucleus is, but since it has 79 protons I guess that means it's gold. Kinetic energy at point of closest approach = 0 Potential energy at the point of closest approach = the kinetic energy that it started with Sorry, what do you mean it's difficult to see...

Rutherford scattering experiment question (urgent) Homework Statement I need to find the value of the electrical force between the alpha particle and the nucleus of the atom at the point of closest approach. Closest approach = 7.27 x 10^-14 m Charge on atom = (79 * 1.60 x 10 ^-19) C initial...
