Automobiles and airplanes: americans on the move

Cinema was not the only major industry to make great technological strides in this decade. The 1920s opened up new possibilities of mobility for a large percentage of the U.S. population, as automobile manufacturers began to mass produce what had once been a luxury item, and daring aviators both demonstrated and drove advancements in aircraft technology. The most significant innovation of this era was Henry Ford’s Model T    Ford, which made car ownership available to the average American.

Ford did not invent the automobile—the Duryea brothers in Massachusetts as well as Gottlieb W. Daimler and Karl Friedrich Benz in Germany were early pioneers. By the early twentieth century, hundreds of car manufacturers existed. However, they all made products that were too expensive for most Americans. Ford’s innovation lay in his focus on using mass production to manufacture automobiles; he revolutionized industrial work by perfecting the assembly line, which enabled him to lower the Model T’s price from $850 in 1908 to $300 in 1924, making car ownership a real possibility for a large share of the population ( [link] ). As prices dropped, more and more people could afford to own a car. Soon, people could buy used Model Ts for as little as five dollars, allowing students and others with low incomes to enjoy the freedom and mobility of car ownership. By 1929, there were over twenty-three million automobiles on American roads.

An advertisement entitled “Watch the Fords Go By” features drawings of two Ford automobiles. The prices are listed at $780 and $725, along with details about each model. In the center of the advertisement, an illustration shows a couple driving along an idyllic country road. At the bottom is the text “Ford Cars Sold by Russell Motor Car Co. 2120-2130 Canal Street, New Orleans, LA. See Our Exhibit Booth at Show.”
This advertisement for Ford’s Model T ran in the New Orleans Times Picayune in 1911. Note that the prices have not yet dropped far from their initial high of $850.

The assembly line helped Ford reduce labor costs within the production process by moving the product from one team of workers to the next, each of them completing a step so simple they had to be, in Ford’s words, “no smarter than an ox” ( [link] ). Ford’s reliance on the moving assembly line    , scientific management, and time-motion studies added to his emphasis on efficiency over craftsmanship.

Ford’s emphasis on cheap mass production brought both benefits and disadvantages to its workers. Ford would not allow his workers to unionize, and the boring, repetitive nature of the assembly line work generated a high turnover rate. However, he doubled workers’ pay to five dollars a day and standardized the workday to eight hours (a reduction from the norm). Ford’s assembly line also offered greater equality than most opportunities of the time, as he paid white and black workers equally. Seeking these wages, many African Americans from the South moved to Detroit and other large northern cities to work in factories.

Ford even bought a plot of land in the Amazonian jungle twice the size of Delaware to build a factory town he called Fordlandia . Workers there rejected his midwestern Puritanism even more than his factory discipline, and the project ended in an epic failure. In the United States, however, Ford shaped the nation’s mode of industrialism—one that relied on paying decent wages so that workers could afford to be the consumers of their own products.

Questions & Answers

Three charges q_{1}=+3\mu C, q_{2}=+6\mu C and q_{3}=+8\mu C are located at (2,0)m (0,0)m and (0,3) coordinates respectively. Find the magnitude and direction acted upon q_{2} by the two other charges.Draw the correct graphical illustration of the problem above showing the direction of all forces.
Kate Reply
To solve this problem, we need to first find the net force acting on charge q_{2}. The magnitude of the force exerted by q_{1} on q_{2} is given by F=\frac{kq_{1}q_{2}}{r^{2}} where k is the Coulomb constant, q_{1} and q_{2} are the charges of the particles, and r is the distance between them.

what is a capacitor?
Raymond Reply
Capacitor is a separation of opposite charges using an insulator of very small dimension between them. Capacitor is used for allowing an AC (alternating current) to pass while a DC (direct current) is blocked.

which has a higher temperature, 1cup of boiling water or 1teapot of boiling water which can transfer more heat 1cup of boiling water or 1 teapot of boiling water explain your . answer
Ramon Reply
I believe temperature being an intensive property does not change for any amount of boiling water whereas heat being an extensive property changes with amount/size of the system.
Someone
Scratch that
Someone
temperature for any amount of water to boil at ntp is 100⁰C (it is a state function and and intensive property) and it depends both will give same amount of heat because the surface available for heat transfer is greater in case of the kettle as well as the heat stored in it but if you talk.....
Someone
about the amount of heat stored in the system then in that case since the mass of water in the kettle is greater so more energy is required to raise the temperature b/c more molecules of water are present in the kettle
Someone

Two bodies attract each other electrically. Do they both have to be charged? Answer the same question if the bodies repel one another.
JALLAH Reply
No. According to Isac Newtons law. this two bodies maybe you and the wall beside you. Attracting depends on the mass och each body and distance between them.

What is specific heat capacity
Destiny Reply
Specific heat capacity is a measure of the amount of energy required to raise the temperature of a substance by one degree Celsius (or Kelvin). It is measured in Joules per kilogram per degree Celsius (J/kg°C).
