Earth’s imaginary spin axis passes through. Our planet also has two magnetic poles: the North Magnetic Pole and the South Magnetic Pole. The magnetic poles are near‚ but not quite in the same places as‚ the geographic poles. The needle in a compass points towards a magnetic pole. However‚ if you are near either pole‚ a compass becomes useless. It points towards the magnetic pole‚ not the true geographic pole. Those two poles could be quite far apart‚ and in different directions. Earth’s magnetic field

ponds‚ and lakes (7). Many anglers fish in freshwater because it is more accessible‚ and fishing in the ocean with a pole‚ due to the fact that a boat is generally used in fishing in the ocean. Fishing from a bank of a lake‚ or a river‚ or even a stream with a pole is certainly the best option. “Freshwater fishing is one of the North America’s most popular sports” (5)‚ and using a pole is a prime way to fish. Rivers‚ lakes‚ and streams are the three main types of freshwater bodies of water that anglers

Over the summer‚ I attended a weeklong hike at Philmont Scout Ranch. I had to pack a variety of gear including clothes‚ food‚ and miscellaneous gear. One particular item I brought was a pair of hiking poles previously used by my brother when he participated in the same hike two years prior. The poles were made of aluminum‚ which was not used for heavy duty hiking but instead for lightweight or short-term hiking. I‚ however‚ did not see any problem with taking them because my brother had no problem

the poles born around the 1600’s and the 1700’s were deemed vulnerable to the religious persecution. The religious persecution was not what the people were looking for‚ so the poles decided to make the move to America. The polish immigrated for several other reasons. One of the main reasons that the polish immigrated was to get work where they were needed. Many poles moved to American because of the fact that they needed people who specialized in building materials for boats and the poles were the

The article by Blonski makes some harsh statements about the role of Poles during the Second World War and Holocaust. He claims that Poland has shared responsibility for the Holocaust and that the Poles were not the victims that they claimed to be. It is not that they did not suffer during the war but that victim was not their only identity. The guilt and responsibility of the Poles is that they were bystanders that could have done for to help the Polish Jews. This article is not about making

A tipi (also tepee and teepee) is a Lakota name for a conical tent traditionally made of animal skins and wooden poles used by the nomadic tribes and sedentary tribal dwellers (when hunting) of the Great Plains. Tipis are stereotypically associated with Native Americans in general but Native Americans from places other than the Great Plains mostly used different types of dwellings. The term "wigwam" (a domed structure) is sometimes incorrectly used to refer to a tipi. The tipi was durable‚ provided

transfer function: R(s) + - E(s) K 1 s(s+a) C(s) How do the poles of the closed-loop system change as a function of the gain K? The closed-loop transfer function is: The characteristic equation: Closed-loop poles: Root Locus When the gain is 0‚ the closed loop poles are the openloop poles Roots are real and distinct and for a positive a‚ in the left half of the complex plane. Two coincident poles (Critically damped response) Roots are complex conjugate with a real part

Then I will make a recommendation of which K value to use. When K=0.1 The poles of this system and the graph are found using the following MATLAB code: >> H=tf([0.1 0.2 0.1]‚[1.2 0.5 1.4 0.1]); >> iopzmap(H); >> poles=roots([1.2 0.5 1.4 0.1]) poles = -0.1718 + 1.0545i -0.1718 - 1.0545i -0.0730 + 0.0000i Since

depends on the number of pairs of poles in the stator field .the rotor speeds n are lower than the table values by the amount of the relevant slip speed ns. Motors are designed with up to three stators windings‚ which have different number of pairs of poles. They can therefore run at up to pairs of poles. They can be in any desired ratio to one another. A pole-changing switch is used to changing poles for the desires speed‚ hence the term pole-changing. The Dahlander pole-changing circuit is a particularly
