Please help with part b and c.

1. (15) The radial component of the wavefunction for a hydrogenic Usefulequations: orbital that was not covered in class is equal to: where Z= nuclear charge, and a0= the Bohr radius (a constant) h=6.6261034Js a. How many radial nodes, where the function inverts c=2.998108m/s through a zero point, are present in this function? (show RH=2.1791018J how you determined this)? J=kgm2/s2 E=mc2 c=v =h/(mv) xmv4h =h/(mv) b. If l=1 (a p orbital) for this wavefunction, how many angular NA=6.0221023 nodes are present? e=9.10941031kg c. Draw a picture of one example of this orbital and label all the nodes as radial or angular (If it is easier, you can draw a 2-dimensional slice of the orbital that shows the key features. Make sure you label the axes)
