The stable nuclei 36Ar and 76Se both differ by 20 inatomic number from 56Fe, which lies at the peak ofthe binding energy per nucleon curve (Figure 12.7).Find B/A for both 36Ar and 76Se. Which one has thelarger B/A? Why is this to be expected?

Physics 2 for Engineering Week 14 Beats 2 sound waves with slightly different frequencies Tbeat= T a b (T -Tb) and f beat= 1 / Tbeat= f a b Tbeatis time it takes to go from minimum to minimum or maximum to maximum Tbeat= nT =a(n-1) T b Doppler Effect f heard by observer depends on relative motion of the source with respect to the observer f’ = f (vsound+- v observer/ (vsound+- v source Depends on relative motion of source and observer Moving towards each other – higher frequency Moving away from each other – lower frequency f is frequency of sound, and f’ is frequency of sound heard by the observer Source at rest, observer moves towards f’ = f (v sound+ v observer / (sound) Source at rest, observer moves away f’ = f (v sound- vobserver/ (vsound) Observer at rest, source moves towards f’ = f (v sound) / (sound - vsource Observer at rest, source moves away f’ = f (v sound / (vsound+ v source
