I have a few problems I could use a little assistance on, Ill give 10 points to the first person that can help. Thanks!
1.A cloud of neutral hydrogen is moving towards us at a speed of 70 kilometers per second. At what wavelength would one observe the radio spectral line characteristic of neutral hydrogen?
2. The first observed nuclear transformation (studied by Rutherford in 1919) was the reaction:
14^N + 4^He --> 17^O + 1^H.
The atomic masses for these elements are:
14^N: 14.0030744 amu
17^O: 16.9991333 amu
4^He: 4.00260326 amu
1^H: 1.00782522 amu
Where the units are 1 amu = 1.66 x 10-27 kg.
a). Determine whether the energy is absorbed or released in the reaction.
b). Calculate the amount of energy (absorbed or released) in this reaction.
