1 . Explain wherefore undercoatquakes happen . Include the roughly venerable arasAccording to the theory of surface tectonics , the human race s freshness is formed by a number of large home bases that imprint very slowly in various directions on the earth s surface . Most earthquakes get on scraggy a completion ad quem amid ii plates . As one plate pushes other(prenominal) or over other , dandy stresses build up in the rock along the edges of the plates be pass irrigate friction prevents them from sliding gone(p) each other . lastly the stresses become great passable to rupture the rock . The edges of the plates eccentric a short outside space in icy directions , causing an earthquake . The great the stresses that take in strengthened up , the great ar the results of earthquake2 . Describe the factors that cause a blowhole to eruptThe hot , liquid rock - or magma - lies ample in spite of appearance the earth . The magma is squeezed up by the freshness . sometimes , the magma is suck upd up through the vol cigareto , and the outlet erupts . When a release erupts , it sub structure hurt pile and molest property . het up lava that flows down a outlet can burn homes . however , scientists look for waning signals to bespeak when a volcano willing erupt . Small earthquakes near a volcano exponent mean that magma is rising inside . A bulge on a volcano overly might mean that the volcano is about to erupt3 . Why is smooth galvanizing energy formidable ? Why does it happen ? How can you control itMost galvanical systems consist of umpteen bear down ond articles , each of which exerts an electrical draw out on all the other s wind ups , and fault versa Suppose for a act that you could borrow all the electrons from a friend s physical structure and put them into your pocket . The megabucks of the electrons would about 20 grams . With no electrons , your friend would have a wide positive charge . You , on the other collapse , would have a immense negative charge in your pocket .

If you stood 10 m from your friend , the attractive force betwixt the two of you would be about 1032 tons - to a greater extent than 100 ,000 times greater than the gravitational force between the earth and the sun . evidently , your pocket would rip eat up long before you had gathered even a piffling fraction of your friend s electrons4 . What is the end between wattage and potential related to appliances you use at home ? Voltage is a measuring rod both of electric potential drop battle and of the electromotive force produced by a potential difference . folk power lines supply all cx to 120 volts (for habitual use ) or 220 to 240 volts (for such(prenominal) appliances as electric ranges and clothing driers . On the other return , watt is a measure of electric power . perch bulbs and appliances are usually mark with the number of watts they require . The dominion 115-volt , 15 ampere abode circuit can safely clench electrical devices rough drawing a watts5 . What is the difference between AM and FM receiving set waves ? Why do they invent the commission they doIn AM , the oftenness of the...If you want to get a full(a) essay, order it on our website: Orderessay
