Effect of ions on living organisms (24 marks) An ion is a charged atom or molecule. This is because it does not have an equal amount of protons and electrons‚ therefore giving the atom an overall charge. An example of an ion is ‚ this is sodium and the plus sign represents an overall positive charge. Ions are very important to living organisms as they are essential for life‚ they play an important role within the cell allowing mechanisms within the living organisms such as respiration‚ to take

Mr. Rowley’s requirement meant that his system‚ which normally drew 1000kVA from the grid‚ would have to be able to utilise 100kVA in order to account for the extra power occasionally needed to start water pumps‚ electric lights‚

Technically its completely distinct to wireless and infrared. Communication possible through any part of the body. Working of Red Tacton: Working of Red Tacton Red Tacton works upon the principle that the optical properties of an electro-optic crystal can vary according to the changes of a weak electric field. 10 mbps transmission speed is achieved between any

Experiment 6 Experiment 6 Some Properties of Charge Introduction: Electrical phenomena were studied extensively during the eighteenth century by scientists and amateurs alike including Benjamin Franklin. Among Franklin’s achievements were contributions to the understanding of electrical behavior beyond his famous (and dangerous) work with lightning. During this time‚ there was a certain social prestige attached to anyone who undertook such studies‚ and much of what passed for

Times named General Electric two years in a row the "Most Respected Company in the World." For any company this is a huge accomplishment and a great recognition. The Fortune poll voted them the country’s "Most Admired Company." The shareholders were somewhat concerned about Welch’s rumored retirement at the end of the year 2000. No one was sure if anyone would take Welch’s place and keep the financial growth that occurred during Welch’s era as leader for General Electric. Thomas Edison founded

Air pollution problem resulted in the development of lung cancer and associated diseases in people. The gasoline car was one of the main factors that released carbon dioxide to the atmosphere‚ which lead to global warming. Facing the risk of devastation

MEN 510 Energy Conversion Assignment 2 Proton Therapy Presented to: Dr. Walid Assaf By: Farid Akiki 20082191 Semester: Fall 2012 Proton Therapy Proton therapy (also called proton beam therapy) is a type of radiation treatment that uses protons rather than x-rays to treat cancer. A proton is a positively charged particle that is part of an atom‚ the basic unit of all chemical elements‚ such as hydrogen or oxygen. At high energy‚ protons can destroy cancer cells.

Cathy Stirling‚ representing Greven E-Coating "Company (Greven) proposed that she prepare samples for each family of housings and provide cost estimates to Glenn. Eager to explore cost savings opportunities‚ Glenn readily agreed. Electrocoating‚ or e-coating‚ uses a system whereby a DC electrical charge is applied

Purpose: The purpose of this lab is to find the electric current when passing through conductors of different shapes and sizes. Also to gain a general knowledge of the laws governing the flow of current through extended conductors is another objective for this experiment. In this lab we are to experiment with the lines of force and equipotentials. We are also to find out vector field and the relationship between the lines of force and the electric field in this lab. Apparatus: Slightly-conducting

RED is used to convey the meaning of warmth in communication. Instead of relying on electromagnetic waves or light waves to carry data‚ a RedTacton transmitter couples with extremely weak electric fields on the surface of the body. The weak electric fields pass through the body to a RedTacton receiver‚ where the weak electric fields affect
