Complete Question
Water is flowing in a trapezoidal channel at a rate of Q=20m³/s . The critical depth y for such a channel must satisfy the equation:
0 = 1 − Q² / gA³c . B Where g= 9.81m /s² and Ac = the cross-section area can be related to depth y by B = 3+y and Ac = 3y+y²/2. Solve for the critical depth using (a). the graphical method,
Answer:
Given the equation,
0 = 1 − Q² / gA³c. B
Now substituting the given value g= 9.81m /s² , Q =20m³/s, B = 3+y, and Ac = 3y+y²/2,
We get:
0 = 1 - 20² / (9.81) ( 3y + y²/2)³ (3+y)
Hence we choose f(y) = 1 - 40.7747 / (3y + y²/2)³ . (3 + y) and solve for f(y) = 0
Therefore,
To solve using a graph, we take twelve sample points ( starting at y = 0.25 in step of 0.25m and plot a graph using MS- Excel. Kindly find the graph below.
2) As evident from the sample point and the graph function f(y) gets close to zero at y = 1.5, hence the root of f(y) = 0 is Xr = 1.5
Answer: Before Patent Expired - Monopoly Market
After Patent Expired - Perfect Competition
Explanation:
Fountain Plus had a patent on Xtrafresh, this means that they alone had legal rights to produce it and others could not produce it without their permission. This gave rise to a Monopoly as there was no competition. Fountain Fresh was able to make ECONOMIC PROFIT because they were able to charge at a price higher than both the Marginal Cost and the marginal revenue of Xtrafresh which were equal to maximize output.
When the Patent expired however and other companies could come into the trade,they started competing in the case of Xtrafresh. This competition meant that Fountain Plus could no longer keep the price at a level above Marginal cost as the other firms would simply charge lower. This led to a situation where the production of Xtrafresh and it's demand became Economically Efficient at Equilibrium. What this means is that Firms had to sell at a price determined by the market and had to make sure that this price equaled their Marginal Revenue and Marginal Cost so therefore no firm was able to make ECONOMIC PROFIT any longer.
Answer:
B. Telephone conversations
Explanation:
Media refers to every broadcasting and narrowcasting medium. A telephone conversation is not a broadcasting/narrocasting medium, given that it cannot transmit information effectively.
