Three-phase electric power is a common method of alternating current electric power generation, transmission, and distribution. It is a type of polyphase system and is the most common method used by electrical grids worldwide to transfer power. It is also used to power large motors and other heavy loads.
A three-wire three-phase circuit is usually more economical than an equivalent two-wire single-phase circuit at the same line to ground voltage because it uses less conductor material to transmit a given amount of electrical power. Polyphase power systems were independently invented by Galileo Ferraris, Mikhail Dolivo-Dobrovolsky, Jonas Wenström, John Hopkinson and Nikola Tesla in the late 1880s.

Answer:
In a monopolistic market, a firm maximizes its total profit by equating marginal cost to marginal revenue and solving for the price of one product and the quantity it must produce. The monopolist's profit is found by subtracting total cost from its total revenue. In terms of calculus, the profit is maximized by taking the derivative of this function
Answer:
Following is the statement in the C language :
if(carYear < 1968)
printf("\nProbably has a few safety features.\n");
if(carYear > 1970 && carYear <=1991 )
printf("\nProbably has head rests.\n");
if(carYear > 1991 && carYear <=2002)
printf("\nProbably has anti-lock brakes\n.");
if(carYear > 2002)
printf("\nProbably has airbags.\n");
Explanation:
Following is the description of the statement:
- In the given question we used if block. The if block is only executed when their condition is true.
- if(carYear < 1968) In this we check we the value of "carYear" variable is less then 1968 then it prints "Probably has a few safety features." in the console window.
- if(carYear > 1970 && carYear <=1991) In this we check we the value of "carYear" variable is greater then 1970 and less then 1992 it prints "Probably has head rests" in the console window.
- if(carYear > 1991 && carYear <=2002 ) In this we check we the value of "carYear" variable is greater then 1991 and less then 2003 it prints "Probably has anti-lock brakes" in the console window.
- if(carYear > 2002) In this we check we the value of "carYear" variable is greater then 2002 then it prints "Probably has airbags" in the console window.
