Prove that Z/ ≡3 has exactly three elements using the
given hint!
Definition: Let R be an equivalence relation on the set A. The set of all equivalence classes is denoted by A/R (g) Prove that Z/ has exactly three elements. Hint: First, verify that [5]3, [7]3, and [013 are three different elements of Z/-3-Then, verify that every m E Z is in one of these sets. Then explain why those two facts imply that [5]3, [7 3, and [013...

Let R be a commutative ring with no nonzero zero divisor and elements r1,r2,.. . ,Tn where n is a positive integer and n 2. In this problem you will sketch a proof that R is a field (a) We first show that R has a multiplicative identity. Sinee the additive identity of R is, there is a nonzero a E R. Consider the elements ari, ar2, ..., arn. These are distinct. To see O. Since R conelude that0, which...

ich has the highest energy? 7. a) Depending upon the kind of models you are using, you may or may not be able to construct models of cyclopropane and cyclobutane. Do so, if possible, but do not break the linkages. Why do we say that these molecules are strained? What is the normal sp3 bond angle? What are the (internal) C-C-C bond angles in cyclopropane? b) Make a model of cyclopentane. Does this molecule seem to have any ring strain...

2.1 In this problem we find the electric field on the axis of a
cylindrical shell of radius R and height h when the cylinder is
uniformly charged with surface charge density . The axis of the
cylinder is set on the z-axis and the bottom of the cylinder is set
z = 0 and top z = h. We designate the point P where we measure the
electric field to be z = z0. (See figure.) You will use...

1. Do you think the fact that most American CEOs are paid so much more than rank-and-file employees suggest CEOs are overpaid? Explain. 2. Japanese CEOs generally receive much lower levels of compensation than CEOs in the United States. Does this imply that U.S. CEOs are overpaid? 3. Is it obvious that $10 per thousand is too low of an incentive to pay for CEOs? Explain. 4. Does the observation that the stock price increases when the firms increase incentive...
