•Q1 At what wavelength does the spectrum of a 10000 K type A star peak?
Use Wien’s Law: λ = 3000000 nm/T, so 300 nm.
•Q2 The neutral atom of the most common form of hydrogen consists of a
proton and an electron.
•Q3 Fusion of very light elements to make heavier ones releases energy, as does fission of very heavy elements
to make lighter ones. The
most "energetically favorable" and stable element from which neither fission nor fusion can
release energy is IRON
•Q5 In the two page spread you can find the solar flare energy in terms of nuclear weapons (up to a billion H-bombs), and determine that yes, the traitor dies like the dog he is!
•Q6 1 kg of mass transformed into energy:
–E = mc2 so E=1 kg x (3x108m/s)2 = 9x1016 J
