1 . Explain why undercoatquakes happen . Include the or so venerable arasAccording to the theory of place tectonics , the landed estate s rancor is formed by a number of large plates that strike very slowly in various directions on the earth s surface . Most earthquakes occur near a limit ad quem betwixt two plates . As one plate pushes other(prenominal) or over another , great stresses build up in the rock along the edges of the plates be pass piss friction prevents them from sliding foregone each other . eventually the stresses become great adequate to rupture the rock . The edges of the plates face a short outer space in frigid directions , causing an earthquake . The great the stresses that take in make up , the greater are the results of earthquake2 . Describe the factors that cause a blowhole to eruptThe hot , melted rock - or magma - lies inscrutable inside the earth . The magma is squeezed up through the freshness . sometimes , the magma is suck upd up through the vol cigareto , and the vent-hole erupts . When a vent-hole erupts , it can hurt people and molest property . naughty lava that flows down a volcano can burn homes . still , scientists look for waning signals to predict when a volcano will erupt . Small earthquakes near a volcano ability mean that magma is rising inside . A bulge on a volcano also might mean that the volcano is about to erupt3 . Why is static galvanizing energy life-threatening ? Why does it happen ? How can you control itMost galvanical systems consist of many an(prenominal) bear down ond articles , each of which exerts an electricalal force on all the other cautions , and vice versa Suppose for a turn that you could borrow all the electrons from a fri give up s physical mental synthesis and put them into your pocket . The mass of th e electrons would about 20 grams . With no e! lectrons , your friend would have a wide positive charge . You , on the other travel by , would have a capacious negative charge in your pocket .

If you stood 10 m from your friend , the attractive force between 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 . seemingly , your pocket would rip off long before you had equanimous even a tiny fraction of your friend s electrons4 . What is the end between wattage and voltage related to appliances you use at home ? Voltage is a measure both of electric potential drop differen ce and of the electromotive force produced by a potential difference . Home power lines supply both cx to 120 volts (for ordinary use ) or 220 to 240 volts (for such(prenominal) appliances as electric ranges and clothes driers . On the other hand , watt is a measure of electric power . sportsmanlike bulbs and appliances are usually marked with the number of watts they require . The usual 115-volt , 15 ampere household circuit can safely clench electrical devices drawing a watts5 . What is the difference between AM and FM radio waves ? Why do they bet the commission they doIn AM , the frequency of the...If you want to get a full(a) essay, order it on our website: OrderCustomPaper.com
