A particle in an infinite square well has the initial wave function :
Ψ(x , 0) = A [(x/L)³ - (3/2)(x/L)² + (1/2)(x/L)]
in the interval 0 < x < L and zero elsewhere.
Find (a) the wave function at a later time, (b) the probabilities of energy measurements, and (c) the expectation value of the energy.

The temperature in gavin's oven is a sinusoidal function of time. gavin sets his oven so that it has a maximum temperature of 280°f and a minimum temperature of 240°. once the temperature hits 280°, it takes 20 minutes before it is 280° again. gavin's cake needs to be in the oven for 30 minutes at temperatures at or above 270°. he puts the cake into the oven when it is at 260° and rising. how long will gavin need to leave the cake in the oven? (round your answer to the nearest minute.)
