  Based on the above figures,Whether profits are earned will depend upon the relationship between P (i.e., price) and ATC (i.e., average total cost) at Q1. if (1)__________, the monopolist will not earn economic profits.  If (2)__________, the monopolist will earn economic profits;

Two 3.6×3.6 cm metal plates are separated by a 0.42 mm thick dielectric material with a dielectric constant of 4.9. What is the capacitance?

Two 6.2×6.2 cm metal plates are separated by a 0.65 mm thick dielectric material with a dielectric constant of 5.8. What is the capacitance?

As a monopolist, the movie theater faces 2 groups of customers, which it can easily distinguish by checking if they have student ID. Student groups have a lower willingness to pay for a movie than the non-student group. Therefore, the monopolist charges different prices to groups of movie consumers with different demands. In this case, this type of price discrimination is: ________________________________
