Adrug company produces a new drug to treat baldness. the inverse demand curve for the drug is p = 205 – 20 q, where q measures the number of pills in millions. the various costs of production are given by tc = 100 + 5 q, atc = 5 + 100/ q, and mc = 5. if the government grants this firm a patent, it will earn profits of if the government revokes the patent and the firm must sell its drug at marginal cost because of competition, it will earn profits of

electromagnetic shielding is the practice of reducing the electromagnetic field in a space by blocking the field with barriers made of conductive or magnetic materials. shielding is typically applied to enclosures to isolate electrical devices from their surroundings, and to cables to isolate wires from the environment through which the cable runs. electromagnetic shielding that blocks radio frequency electromagnetic radiation is also known as rf shielding.

the shielding can reduce the coupling of radio waves, electromagnetic fields and electrostatic fields. a conductive enclosure used to block electrostatic fields is also known as a faraday cage. the amount of reduction depends very much upon the material used, its thickness, the size of the shielded volume and the frequency of the fields of interest and the size, shape and orientation of apertures in a shield to an incident electromagnetic
