Find the scattering amplitude, in the Born approximation, for soft-sphere scattering at arbitrary energy. Show that your formula reduces to Equation 10.82 in the low-energy limit.

Hahahahaha nice. my guess would be age or they moved the grocery store. ; ) and remind him next time you are late getting home that it takes a long time to go 12miles, hahahave a good one!

Is this a question of an answer

Attach the free body diagram and i will you answer the question.! : d

The boat's velocity relative to the riverbank can be resolved into two components. the component going north is 2.7 m/s and the component going west is 1.2 m/s.we add these two vectors and then find the magnitude of the resultant to get the speed.the magnitude of the resultant vector from adding can be obtained by the pythagorean theorem.    to two significant figures, the boat's speed relative to the riverbank is 3.0 m/s.
