Over the entire earth, there are 60,000 km of active rift zones, with average separation rates of 5 m/century. how much area of new ocean crust is created each year over the entire planet? (this area is approximately equal to the amount of ocean crust that is subducted since the total area of the oceans remains about the same.)

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
