Starting with the canonical commutation relations for position and momentum a) evaluate l , d ili, pi, where l1-tijkr, pk b) evaluate [l,. lj] c) evaluate [li. 2] and [l,.p] d) show that the hamiltonian ril an h=l, v(r) 2m commutes with l hint: be careful with the indices!

Is this a question of an answer

The chemical reactions lab we did is typically called a "copper plating lab,  because the acid solution cleaned the pennies and made the copper look shinier;   the acid solution cleaned the paperclips and made them look like pennies;   &   the copper from the pennies was removed, and then added to the paperclips. 

None. nothing. zero. zilch.
