Q. Why do wire and a compass work to detect electric currents? A. I’m going to start off with the basics here. A compass points north. Everyone knows that. Why does it point north? Well, all magnets have two “poles” or ends. One end of the magnet is called the north-seeking pole. The north-seeking pole is often abbreviated to north pole or the letter N. The north pole end of a magnet is usually colored red. The other end of a magnet is called the south-seeking pole. The south-seeking pole is…

The Human Battery Do males or females produce the most electric current? Abstract The Human Battery Do males or females produce the most electric current? Abstract The purpose of this project was to determine whether males or females produce the most electric current. An aluminum plate, a copper plate, a micro ammeter, two lead wires with alligator clips, water, notebook paper, and pencil were used as materials. It was predicted that males would produce a greater electric…

solve this problem. SDS is a detergent or soap that is used to transfer negative charges to the proteins by mass and to denature the secondary, tertiary, and quaternary structure of the protein. SDS can dissolve hydrophobic molecules, but also has a negative charge. So the membranes of the cells will dissolve and the protein will be denatured to a primary (or linear) structure and the SDS will apply a negative charge to the whole protein strand. Also common when using protein gel…

At the water molecule occurs the covalent bond. Hydrogen has an inferior electronegativity compared with oxygen.4 Oxygen attracted the negatively charged electrons, and it makes the oxygen has a negative charge. 4 The opposite applies to hydrogen, and makes it has a positive…

Background Information Electricity is a form of energy resulting from the build-up of charged particles, either statically as an accumulation of charge or dynamically as a current (Oxford dictionary, 2015). The effect of electricity can be seen in play daily, whether through a simple light bulb, or a complex application such as providing energy to a power plant. It is often stated that electricity is the most versatile and easily controlled form of energy, and at the point of use it is…

The world that we all know today is going to come to an end! Living with our parents is fun and games now but the moment we step into the real world is an eye opener. We live in a world where almost everything is handed to us, but if you ever thought about it, your parents are the superheroes of the day because they pay for everything; all our clothes, shoes, housing, electronic, etcetera bills. Taking care of yourselves in the real world is not as easy as 1,2,3.…

negatively charged beta particle due to the lack of neutrons to hold the particles together which will, in turn, throw the balance of the particles off making it unstable.Beta particles are shown by the symbol which shows that the beta particle has a charge of -1 this also give it an almost massless effect as well.Beta particles travel at very high speeds almost at the speed of light although it exact speed can vary.Alpha particles have the same structure as a helium nucleus of 2 neutrons and 2…

shows that other prisons are charging inmates a certain dollar amount for every day they are incarcerated and additional charges for things such as parole, visitation, and probation. Vega and Rawlings also tell their readers the affects these charges have on inmates post prison. Now there are many other articles just like these two. These two articles show the facts concerning charges inmates have to…

Imagine a world without electricity, a period of prolonged darkness, not just a brief power outage. Attempt to envision a world where time does not exist. Sounds abnormal, yet for the greater part of human presence, this is the means by which we lived. The sun was the nearest instrument we had to a clock, and it contained all the information we desired. Endeavor to picture a world where there is no such thing as a stove to cook an evening feast for your growing family; no television to watch…
