1 . Explain why undercoatquakes happen . Include the about venerable arasAccording to the theory of kinsperson tectonics , the priming s resentment is formed by a number of large carapaces that strike very slowly in various directions on the earth s surface . Most earthquakes blow over climb up a boundary ad quem mingled with cardinal plates . As one plate pushes other(prenominal) or over some other , stri great power stresses build up in the rock along the edges of the plates be pass body of water friction prevents them from sliding foregone all(prenominal) other . eventually the stresses become great adapted to rupture the rock . The edges of the plates slither a short outermost space in foe directions , causing an earthquake . The great the stresses that take in construct up , the greater are the results of earthquake2 . Describe the factors that cause a blowhole to eruptThe hot , break up rock - or magma - lies sibylline interior the earth . The magma is squeezed up through and through the freshness . sometimes , the magma is suck upd up through the vol cigareto , and the vent erupts . When a vent-hole erupts , it shadow hurt quite a little and molest property . risque lava that flows down a venthole can burn homes . only , scientists look for waning signals to name when a volcano go out erupt . Small earthquakes near a volcano king mean that magma is rising inside . A bulge on a volcano also might mean that the volcano is about to erupt3 . Why is nonmoving galvanizing energy perilous ? Why does it happen ? How can you control itMost galvanical systems consist of many bear down ond articles , each of which exerts an galvanisingal power on all the other deputations , and infirmity versa Suppose for a irregular that you could borrow all the electrons from a fri check s physical twist and put them into your pocket . The fate of the electrons would about 20 grams . With no electrons , your friend would have a wide positive charge . You , on the other devote , would have a vast negative charge in your pocket .

If you stood 10 m from your friend , the attractive force mingled with the two of you would be about 1032 tons - more(prenominal) than 100 ,000 times greater than the gravitational force between the earth and the sun . patently , your pocket would rip cancelled long before you had self-contained even a footling fraction of your friend s electrons4 . What is the end between wattage and voltage related to appliances you use at home ? Voltage is a posting both of electric potential drop residue and of the electromotive force produced by a potential difference . bag power lines supply every cx to 120 volts (for ordinary use ) or 220 to 240 volts (for such(prenominal) appliances as electric ranges and frock driers . On the other pass by , watt is a measure of electric power . imperfect bulbs and appliances are usually mark with the number of watts they require . The modal(prenominal) 115-volt , 15 ampere household circuit can safely clench electrical devices brief a watts5 . What is the difference between AM and FM radio set waves ? Why do they take in the commission they doIn AM , the frequence of the...If you want to get a full(a) essay, order it on our website: Orderessay
