27. An electron is in the $n = 1$ eigenstate of a one-dimensional infinite square-well potential which extends from $x = -a/2$ to $x = a/2$. At $t = 0$ a uniform electric field $E$ is applied in the $x$ direction. It is left on for a time $\tau$ and then removed. Use time-dependent perturbation theory to calculate the probabilities $P_2$ and $P_3$ that the electron will be, respectively, in the $n = 2$ and $n = 3$ eigenstates at $t > \tau$. Assume that $\tau$ is short in the sense that $\tau \ll \frac{\hbar}{E_1 - E_2}$, where $E_n$ is the energy of the eigenstate $n$. Specify any requirements on the parameters of the problem necessary for the validity of the approximations made in the application of time-dependent perturbation theory.

Research has shown that the relationship between the price of a cup of coffee, p in dollars, and the demand, x in number of cups sold (per day), is p = 6 - 0.1x The Elasticity of Demand can be written as a formula $E(p) = \frac{-pf'(p)}{f(p)}\ Where \(E(p)$ is the elasticity, p is the unit price, and x = f(p) is the demand. a. Find the elasticity of demand formula for a cup of coffee. \(E(p) =\ b. Use the elasticity of demand formula to fill out the following table. Interpretation: If the price is increased by 10%... Price of cup of coffee Elasticity of Demand The price is ... $1 $2 $3 $4 $5
