Homework Statement which values can the quantum numbers j and J take on, can they take on the value 0? Homework Equations The Attempt at a Solution j=l+s and both l and s can be 0 so j can become zero, am I right?

the second one is at rest, and there is no energy loss.

Homework Statement We have two objects of mass m1. The first object is moving towards the second and has speed u. After they collide, they stick together and move as one mass with speed v. Now what is the resulting mass and what is v? Homework Equations The Attempt at a...

I want to integrate something in spherical coordinates I have da=R^{2}sin(g)dgdh \hat{r} with g and h angles and \hat{r}=sin(g)cos(h) \hat{i}+sin(g)sin(h) \hat{j}+cos(g) \hat{k} But what is now da_{x}=dydz \hat{i} in spherical coordinates? So I have the expression in ordinary...
