An excited iron (Fe) nucleus (mass 57u) decays to it's groundstate with the emission of a photon. The energy availabel from thistransition is 14.4 KeV
A) By how much is the photon energy reduced from the full 14.4KeV as a result of having to share energy with the recoilingatom?
B) What is the wavelength of the emitted photon?
A light spring with a spring constant of 80.0 N/m rests vertically on a table. A 2g balloon is filled with helium (0°C and 1 atm pressure) to a volume of 5.00 m3 and connected to spring, causing the spring to stretch and expand. How much does the ..
