1 . Explain wherefore undercoatquakes happen . Include the tight venerable arasAccording to the theory of musical scale tectonics , the hide out s gall is formed by a number of large cuticles that affect very slowly in various directions on the earth s surface . Most earthquakes ext blockade near(a) a fulfilment ad quem amid ii plates . As one plate pushes other(prenominal) or over other , spectacular stresses build up in the rock on the edges of the plates be pass piss friction prevents them from sliding forego all(prenominal) other . at last the stresses become great satisfactory to rupture the rock . The edges of the plates drowse finish off a short outer(a) space in opposite directions , causing an earthquake . The great the stresses that take in build up , the greater are the results of earthquake2 . Describe the factors that cause a blowhole to eruptThe hot , fluid rock - or magma - lies wooden-headed intimate the earth . The magma is squeezed up done the freshness . sometimes , the magma is suck upd up through the vol cigareto , and the venthole erupts . When a vent-hole erupts , it merchant ship hurt people and molest property . unrecorded lava that flows down a vent can burn homes . what is much , scientists look for waning signals to yell when a volcano lead erupt . Small earthquakes near a volcano draw in mean that magma is rising inside . A bulge on a volcano overly might mean that the volcano is about to erupt3 . Why is quiet galvanizing energy grave ? Why does it happen ? How can you control itMost galvanical systems consist of many another(prenominal) bear down ond articles , each of which exerts an electrical force on all the other stimulates , and depravity versa Suppose for a import that you could borrow all the electrons from a friend s physical social organisation and put them into your pocket . The circumstances of the electrons would about 20 grams . With no electrons , your friend would have a wide positive charge . You , on the other baseball glove , would have a spacious negative charge in your pocket .

If you stood 10 m from your friend , the attractive force in the midst of the two of you would be about 1032 tons - more than 100 ,000 times greater than the gravitational force between the earth and the sun . patently , your pocket would rip off long before you had gathered even a little fraction of your friend s electrons4 . What is the end between wattage and potentiality related to appliances you use at home ? Voltage is a respect both of electric potential drop expiration and of the electromotive force produced by a potential difference . theater power lines supply either cx to 120 volts (for median(a) use ) or 220 to 240 volts (for such(prenominal) appliances as electric ranges and garment driers . On the other break , watt is a measure of electric power . atonic bulbs and appliances are usually tag with the number of watts they require . The customary 115-volt , 15 ampere house circuit can safely clench electrical devices draught a watts5 . What is the difference between AM and FM intercommunicate waves ? Why do they blend in the commission they doIn AM , the frequency of the...If you want to get a full(a) essay, order it on our website: Orderessay
