It is a natural process of animal species to become extinct (e.g. dinosaurs, dodos etc.). There is no reason why people should try to stop this from happening. Do you agree or disagree? Give reasons for your answer and include any relevant examples from your own knowledge or experience....
The Noor solar power station is 26___ in the city of Ouarzazate and, once completed, will generate 580 million watts of electricity. The World Bank estimates it will serve 1.1 million people. It’s 27___ to be ...
Static electricity or ESDis an electrical charge at rest. This is created by an imbalance of electrons that stay on a specific surface, or in the environmental air. The imbalance of electrons is caused by absence or surplus of electrons. This creates an electrical field that is capable of in...
A battery has two ends -- a positive terminal (cathode) and a negative terminal (anode). If you connect the two terminals with wire, a circuit is formed. Electrons will flow through the wire and a current of electricity is produced. Inside the battery, a reaction between chemicals take pl...
Electricity Definition: Electricity is the flow of electrons between two points, created by the imbalance in electron and proton numbers. Generation Methods: Electricity is generated through electromechanical, electrochemical, and solid-state processes. ...
How much electricity is in the human body? Scientists agree that the human body, at rest, can produce around 100 watts of power on average. This is enough electricity to power up a light bulb. Some humans have the ability to output over 2,000 watts of power, for instance if sprinting....
The man can come back sometime later. D) She can pass on the message for the man. 16. A) He has a strange personality. B) He s got emotional problems. C) His illness is beyond cure. D) His behavior is hard to explain. 17. A) The tickets are more expensive than expected. B)...
The current is said to be an alternating current because it rapidly changes direction. The power distribution grid delivers electricity at a consistent voltage (120 and 240 volts in the United States), but resistance (and therefore current) varies in a house. All of the different light bulbs ...
In order for electricity to flow, a current has to be created and maintained. This is done using a generator device. Generators are what keep the electrons stimulated and moving. This process of generating energy, in effect, creates more and more of the same. Once a current of energy, or...
Using a reversible turbine, the plant can pump water back to the upper reservoir. This is done in off-peak hours. Essentially, the second reservoir refills the upper reservoir. By pumping water back to the upper reservoir, the plant has more water to generate electricity during periods of pea...
