Federal government assistance

To assist the settlers in their move westward and transform the migration from a trickle into a steady flow, Congress passed two significant pieces of legislation in 1862: the Homestead Act and the Pacific Railway Act. Born largely out of President Abraham Lincoln’s growing concern that a potential Union defeat in the early stages of the Civil War might result in the expansion of slavery westward, Lincoln hoped that such laws would encourage the expansion of a “free soil” mentality across the West.

The Homestead Act allowed any head of household, or individual over the age of twenty-one—including unmarried women—to receive a parcel of 160 acres for only a nominal filing fee. All that recipients were required to do in exchange was to “improve the land” within a period of five years of taking possession. The standards for improvement were minimal: Owners could clear a few acres, build small houses or barns, or maintain livestock. Under this act, the government transferred over 270 million acres of public domain land to private citizens.

The Pacific Railway Act was pivotal in helping settlers move west more quickly, as well as move their farm products, and later cattle and mining deposits, back east. The first of many railway initiatives, this act commissioned the Union Pacific Railroad to build new track west from Omaha, Nebraska, while the Central Pacific Railroad moved east from Sacramento, California. The law provided each company with ownership of all public lands within two hundred feet on either side of the track laid, as well as additional land grants and payment through load bonds, prorated on the difficulty of the terrain it crossed. Because of these provisions, both companies made a significant profit, whether they were crossing hundreds of miles of open plains, or working their way through the Sierra Nevada Mountains of California. As a result, the nation’s first transcontinental railroad was completed when the two companies connected their tracks at Promontory Point, Utah, in the spring of 1869. Other tracks, including lines radiating from this original one, subsequently created a network that linked all corners of the nation ( [link] ).

A photograph shows the ceremony commemorating the completion of the first transcontinental railroad. Samuel S. Montague and Grenville M. Dodge, chief engineers of the Central Pacific and Union Pacific Railroads, respectively, shake hands symbolically in front of two locomotives and a crowd of workers.
The “Golden Spike” connecting the country by rail was driven into the ground in Promontory Point, Utah, in 1869. The completion of the first transcontinental railroad dramatically changed the tenor of travel in the country, as people were able to complete in a week a route that had previously taken months.

In addition to legislation designed to facilitate western settlement, the U.S. government assumed an active role on the ground, building numerous forts throughout the West to protect and assist settlers during their migration. Forts such as Fort Laramie in Wyoming (built in 1834) and Fort Apache in Arizona (1870) served as protection from nearby Indians as well as maintained peace between potential warring tribes. Others located throughout Colorado and Wyoming became important trading posts for miners and fur trappers. Those built in Kansas, Nebraska, and the Dakotas served primarily to provide relief for farmers during times of drought or related hardships. Forts constructed along the California coastline provided protection in the wake of the Mexican-American War as well as during the American Civil War. These locations subsequently serviced the U.S. Navy and provided important support for growing Pacific trade routes. Whether as army posts constructed for the protection of white settlers and to maintain peace among Indian tribes, or as trading posts to further facilitate the development of the region, such forts proved to be vital contributions to westward migration.

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
definitely of physics

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).
