Consider a two-dimensional square potential energy well with sides of length l. the potential energy is infinite at the sides and zero inside. the single-particle energies are given by (h2/8ml2)(m + n, where nr and ny are integers. report all energy values in units of (h/8ml2) (a) (5 points) what is the energy of the ground state? (b) (5 points) what is the energy of the first excited state? (c) (5 points) what is the degeneracy of the first excited state? (d) (10 points) if we put three electrons into this potential energy well, what would the energy of the ground state be?

Awater balloon launcher uses an elastic band with a spring constant of 115 n/m to use thee launcher you stretch thee band back with a balloon n it the water balloons have a mass of 1.3 kg a) if you stretch the band by 0.8 m, what elastic force will the band exert? b) with the band stretched 0.8 m, how much elastic potential energy is stored in the spring? c) if you release the band, it pushes forward. what is the kinetic energy of the balloon when it reaches the natural length of the band? d) what is the speed of the balloon when it reaches the natural length of the band?
