HW 1 solutions Point Charge in One Dimension A point charge q1 = -3.5 μC is located at the origin of a co-ordinate system. Another point charge q2 = 5.1 μC is located along the x-axis at a distance x2 = 9.3 cm from q1. 1) What is F12‚x‚ the value of the x-component of the force that q1 exerts on q2? -18.57 N For all of these problems we want to make use of the standard electric force equation: ̂ So for this problem with K=9*109 Nm2/C2‚ Q1=-3.5μC‚ Q2=5.1 μC‚ and r=9.3 cm we get F=-18.57

The Gallant Charge of the 54th Massachusetts (Colored) Regiment In United States’ history‚ there has never been a battle as influential and graphic as the Civil War (1861-1865). It was a revolution in several aspects‚ especially in media‚ becoming responsible for the first great surge of artistic representations during events of its time. Several of these depictions included certain aspects of the war such as the literal battlefield‚ fugitives and death--all of which is portrayed in The Gallant

The NCO Creed and NCO Charge were made so an NCO would have a precise understanding of his responsibilities in the United States Army. I neglected those responsibilities and disrespected the backbone of the United States Army. Below is my understanding of how the NCO Creed and NCO Charge apply to this situation. No one is more professional than I. I am a Noncommissioned Officer; a leader of people. I am proud of the Noncommissioned Officer corps and will‚ at all times‚ conduct myself so as to

Battle of Gettysburg at the end of the three days. Pickett’s Charge was the highest point of the Battle of Gettysburg. The charge took place on the third day of the battle. Robert E. Lee ordered Pickett’s Charge. It involved an infantry assault of approximately 15‚000 Confederate soldiers against Union Major George Meade’s troops (History Net). This was along Cemetery Ridge‚ manned by 6‚500 Federals (History Net). The whole point of this charge was to fire cannon the entire time. The ill-fated assault

Electricity is the force that holds together the molecules and atoms of all substances. The type of electricity that is most familiar to us is electrical current. This is the flow of electrical charges through a substance called a conductor such as a metal wire. This flow happens beacuse some of the negatively charge electrons circling the nuclei of the conductor’s are held loosely. The electrons can move from one atom to the next‚ producing and electrical current. Electricity has become something we

The film included accurate events that may have occurred to people in Australia during the period of time leading up to and during the war in Gallipoli in WW1‚ including their enrolment‚ but it misrepresents some major aspects of history. The charge at the Nek was one of the major scenes‚ and my research has shown some of the parts to be historically incorrect. The scenes of the film that encouraged enrolling in the army and the impact enrolling had on family and friends were mainly accurate

force is caused by electric charge. Electric charge is a property of the bits of matter within atoms. Electric force can cause matter to attract or repel because there are two kinds of charge – positive and negative charge. The effects of electric force can be summarized as the law of electric charge: Pieces of matter with the same kind of charge repel each other. Pieces of matter with the same kind of charge attract each other. 2 objects with a positive charge repel each other‚ as do 2 objects
