For a perfectly competitive firm with no market control, the marginal revenue curve is a horizontal line. Because a perfectly competitive firm is a price taker and faces a horizontal demand curve, its marginal revenue curve is also horizontal and coincides with its average revenue (and demand) curve.Yes-what you must remember is that a firm's demand curve in perfect competition is its average revenue curve.Average revenue = price x quantity / quantity = price. The demand curve shows the quantity demanded at varying prices and this is exactly what the average revenue curve will do. Answer   Because for a perfectly competetive firm since the demand curve is perfectly elastic even a slightest price change doesnt add any further demand..so there â¦ is no change in marinal revenue also.Since revenue is demand multiplied with cost of unit..the two curves are same. + 1 other found this useful.
Natural gas can be measured in a variety of ways, although the most common unit of measurement is the Gigajoule (GJ), which signifies one billion joules, the metric measure for heat or energy. Other measures are Mcf (thousand cubic feet) and Btu (British Thermal Unit).
In either case, when the containers are full, the pressure is approximately 15 atm. At this pressure and at room temperat ure, 85% of its volume is in the liquid state and 15 % is in the vaporous state. When natural gas is used in vehicles (VNG-vehicular natural gas), it is sold at service stations at 200 atm pressure, which is the final pressure in the vehicle's cylinder. Under these conditions, the quantity of natural gas in the cylinder is approximately 30 kg.
