Four different particles are trapped in one dimensional wells with infinite potential at the walls and zero potential inside. The masses of the particles and their energy level, n , are given by:
1. mass=m, n=1
2. mass=2m, n=2
3. mass =3m, n=3
4. mass=4m, n=2
All these wells have the same length L. Rank the kinetic energy of the particles in order of size, smallest to largest.
Group of answer choices
E3 <E1<E2<E4
E1 = E4 < E2 < E3
E4 <E3 <E2 = E1
E1 < E2 = E4 < E3
E1 < E2 = E3 <E4
One model that is used for the interactions between animals, including fish in a school, is that the fish have an energy of interaction that is given below by a Morse potential. The fish will attract or repel each other until they reach a distance that minimizes the function V(r). The coefficients A and a are positive numbers. Complete parts (a) through (c).
V(r)=e^-r -Ae^-ar, r>0
Find the value of r that minimizes V(r).
