Hi I need help with both questions for an upcoming test. Please
help! Thanks for the...
2. Rutherford Scattering Protons are shot into a copper foil with d-12 μm. what is the proton energy if the central collisions minbecome equal to the nuclear radius r copper atoms? The derivation of the impact parameter with respect to deflection angle is obtained by assuming a Coulomb potential of the form F x 1/r2 (equation 4.12 in Haken-Wolf textbook). Derive the impact parameter in which the potential is of the form F α 1/ Hint: Derivation in Demtröder textbook page 67-68 would be helpful. a) 5x 10-15m of the b) 3. Black Bodv Radiation What is the temperature of a black sphere with a diameter of 10 cm which is emitting a total of 100 W thermal radiation? How much mass is lost each year by being radiated away?
