Current Attempt in Progress Use of the effective-interest method to amortize bond premiums and discounts results in O a varying amount being recorded as interest income from period to period. O a smaller amount of interest income over the life of the bond issue than would result from the use of the straight-line method. O a variable rate of return on the book value of the investment. O a greater amount of interest income over the life of the bond issue than would result from the use of the straight-line method. Save for Later Attempts: 0 of 1 used Submit Answer

ABC, Inc. purchases the business assets of XYZ, Inc. for $100,000. The business assets are valued as follows: Asset Machine #1 Machine #2 Computer FMV $30,000 $50,000 $10,000 What is the tax treatment of the $10,000 of purchase price paid in excess of the FMV of the assets purchased? O It is a deductible expense/loss in the year of purchase O It is added to the basis of the purchased assets (allocated based on relative FMV) O It represents Goodwill, which can be amortized over 180 months O It represents Goodwill, which cannot be amortized (instead tested annually for impairment) O It represents a non-deductible/non-recoverable expense

Consider a particle with spin-1. Let {|+?, |0?, |??} denote the (orthonormal) eigenstates of $\hat{S}_z$ (with $\hat{S}_z|m? = \hbar m|m?$). a. In terms of the $\hat{S}_z$-eigenstate basis, write the matrix representations of the operators $\hat{S}^2$, $\hat{S}_x$, $\hat{S}_y$, and $\hat{S}_z$. (Hint: Start with $\hat{S}_z$ and $\hat{S}^2$; then you should consider $\hat{S}_±$ to determine $\hat{S}_{x,y}$.) b. Staying in this basis, what are the appropriately normalized eigenstates of $\hat{S}_x$ and $\hat{S}_y$? That is, determine the representation of these eigenstates in the basis of $\hat{S}_z$ eigenstates.
