highly technological society. There are many energy sources that can be readily converted into electricity. In Australia‚ most power plants burn a fuel‚ such as coal‚ or use the energy of falling water to generate electricity on a large scale. Electricity is also relatively easy to distribute. Electricity authorities use high-voltage transmission lines and transformers to distribute electricity to homes and industries around each state. Voltages can be as high as 5 × 105 volts from power stations

The Pit and the Pendulum by Edgar Allen Poe‚ and The Lowest Animal by Mark Twain have many differences but one central theme. They both express the belief that the human race can be destructive. Both stories have very different settings. Poe’s story The Pit and the Pendulum takes place in a completely pitch black room. From lines 102 - 103 the narrator says‚ “the blackness of eternal night encompassed me”(pg.252). The narrator wakes up and tries to navigate and almost falls in a pit. He was put

several different graphs. A velocity vs. time graph can be used to describe both acceleration and displacement. Acceleration is shown by the slope of the graph‚ displacement by the area. Billy and Crystal both took a short car trip along a road heading straight west from their house. They recorded their velocity every second. After they got home‚ each of them added their data to the graph above. Write Using physics vocabulary‚ compare/contrast Billy’s and Crystal’s trip. Be sure to – understand

The Effects of Gravity There are some people who worry that when they ’re outside‚ if they don ’t keep a good grip on the ground‚ they ’ll just go flinging off into space. They needn ’t really worry about this‚ because gravity generally keeps that sort of thing from happening. The thing is‚ no one is really sure what causes gravity‚ but the effects have been studied by many physicists and astronomers. Three of the more obvious effects of gravity are things falling down‚ weight
