A cart of mass 0.5kg is attached to a block of mass 0.9kg by a uniform rope that passes over an ideal pulley fixed to the corner of a table, as shown in the diagram
above. The system is released from rest and the cart begins accelerating to the right
as the hanging block accelerates downwards. Assume the cart rolls with negligible
friction in its axles.
Calculate the acceleration of the cart. Round your answer to the nearest tenth.

An electron is trapped at a defect in a crystal. the defect may be modeled as a one-dimensional, rigid-walled box of width 1.00 nm. (a) sketch the wavefunctions and probability densities for the n 1 and n 2 states. (b) for the n 1 state, nd the probability of nding the electron between x1 0.15 nm and x2 0.35 nm, where x 0 is the left side of the box. (c) repeat (b) for the n 2 state. (d) calculate the energies in electron volts of the n 1 and n 2 states
