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

I do believe that the proposal should be accepted. The reason being the Clark project has a positive NPV. The net present value method offsets the present value of an investment’s cash inflows against the present value of the cash outflows. If the present value of cash inflows exceeds the present value of cash outflows‚ then it clears the minimum cost of capital and is deemed to be a suitable undertaking. On the other hand‚ if the present value of cash inflows is less than the present value of cash

The Lewis and Clark expedition ignited a period of expansion for the US. The enormous amount of new discoveries of all the new plant and animal species gave the United States a monopoly over certain products only found in the west. Ideas knowledge learned from the Indians influenced western medicine and helped shape diverse lifestyles‚ which provided the West with a much-needed break from the archaic ways of British living. The new geography discovered on the journey coaxed others to follow the expedition’s

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

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

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

Human development is a process of growing into maturity. Human development entails growth from a one cell zygote to an adult human being. Human development lets us know who we are and it shows us how we interact on a day to day basic. Within the foundation of human development we learn to understand bio-psychosocial dimensions‚ the concept of human diversity and cultural competence as well as the connection of general systems and social order. All of these characteristics are put in place so you can
