infinitely long wire that carries a current I. Your derivation should include the direction of the magnetic field with respect to the direction of current flow. Verify your expression by using the experimental results obtained. If your results do not show the expected relationship‚ explain why. In order to derive an expression for the magnetic field B at a point of distance r‚ from an infinitely long wire that carries a current I‚ we can refer to fig. 10. From symmetry‚ B must be constant in magnitude and

Step Down DC to DC Converter Ivana Krezzel T. Almazan and Ruphina G. Gomez Introduction In our world today‚ cellphones‚ and laptops are widely used. For some‚ these things are so important especially for students and employers who work from office. These devices are usually operated with battery. A DC to DC converter is an electronic circuit which converts a source of direct current (DC) from one voltage level to another. DC is not easily being stepped up or down. One of the applications

The Force Between Two Parallel Current Carrying Conductors Aim: To observe the direction of the forces between two parallel CCDs. Hypothesis: That the CCD with current flow in the same direction will be attracted to each other and CCDs with current flow in opposite directions will repel. Apparatus: -Variable DC power supply * Variable resistor (15ohm rheostat) * Connecting wires * Retort stand * Clamp * Two pieces of thick card or balsa wood 10cmx10cm * Two strips of

Carrying Capacity 1. The carrying capacity is the size of a population that can live indefinitely using the resources available where that population lives 2. For example‚ consider an island onto which is dropped a colony of rabbits. As long as there is an adequate supply of food and water‚ the rabbits will not only survive but they will reproduce and the colony will get larger. 3. The rabbit population can continue to grow as long as food and water are adequate. However‚ if at some point‚ there

that the government should shut down the fast food industry. If the people of America want their eating habits to be unhealthy and don’t care about the consequences then let them go for it. Also if the government does shut down the fast food industry then he is shutting down so much jobs and job opportunities like a fry cook‚ a cashier‚ a drive-thru talker‚ a doctor and so many more (not really) job opportunities. And if the people of America don’t know that the food they eat kills them then the government

Name: Chris Cohick Title of Article: What is Carrying Capacity? Author and Brief Background: Kip Adams‚ QDMA Director of Education & Outreach‚ northern U.S Date of Submission: June 27‚ 2009 Carrying Capacity When first inquiring into this article‚ it gave me the impression it was going to just define carrying capacity. After further looking into it‚ I then realized it relates carrying capacity to having a successful quality deer management area. The two concepts really go hand in hand

ESAU GARCIA WHAT HAPPENED TO THE LIONS????? BIOLOGY March 5 2012 Mrs Loughney INTRO Extinction is a problem that has been around since the beginning of time. An organism might go extinct for many reasons. Some reasons might be Mother Nature. Man also plays a part as they might over hunt the organism and drive it to extinct. But another cause is natural selection and the belief that only the strong will survive in this game we call life. Many problems can happen because of extinction
