Three Styrofoam balls are suspended from thin threads. Various objects are then rubbed against each other (wool against plastic, silk against glass, etc...) and each Styrofoam ball is charged by toughing. It is found that balls 1 and 2 repel each other and that balls 2 and 3 attract each other. From this we can conclude (check all that apply). 2 and 3 carry charges of the same sign we need more information to determine the sign of the net...

State whether the following statements are true, false or uncertain and briefly explain the reason for your choice. Your grade will largely depend on the quality of your explanations. a. Suppose that a firm’s short-run total cost function is STC= 0.1q2 + 4q +100. Will the producer surplus at P=$15 be $302.5? b. Suppose that a firm is price taker. If the price is equal to marginal cost, then the profit is being maximized. c. If a firm wished to...
