In this part of Lesson 4‚ we will ponder two questions: * What is the cause and mechanism associated with lightning strikes? * How do lightning rods serve to protect buildings from the devastating affects of a lightning strike? Static Charge Buildup in the Clouds The scientific community has long pondered the cause of lightning strikes. Even today‚ it is the subject of a good deal of scientific

electric current. Since the negatively charged electrons are moving to the left‚ the current‚ which is defined as the "flow" of positive charge‚ moves to the right. Given that the positively charged nuclei do not move‚ why does the right end of the rod become positively charged? The reason is that some electrons have moved to the left end‚ leaving an excess of stationary nuclei at the right end. An electric field that exists in an isolated conductor will cause a current flow. This flow sets up

an object changes with a change in temperature while the pressure is held constant. We ’re able to determine the theoretical coefficient of linear expansion of the two metals by substituting the values we acquired in measuring the length Lo of the rod at to (before we heated the sample metal) and the length ΔL at tf after we heated the metal. We used the digital multi tester that shows the resistance of the thermistor with correspond temperature on the table below. We had seen how the both copper

valve rod connected directly to a control valve fitted into the steam inlet pipe. The control valve either reduced or increased steam admission to the engine as required. When the steam engine increased in speed‚ possibly due to reduced loading of the engine‚ the fly balls would be forced out by centrifugal force thus moving the sleeve against‚ as in this case‚ spring tension. As the fly balls moved out‚ the central sleeve would be forced upwards which in turn moved the bell crank‚ valve rod and control

physiological process which means that it is the same for everyone. We absorb energy such as electro magnetic energy (light) or sound waves by sensory organs such as eyes. This energy is then transduced into electro chemical energy by the cones and rods (receptor cells) in the retina. There are four main stages of sensation. Sensation involves detection of stimuli incoming from the surrounding world‚ registering of the stimulus by the receptor cells‚ transduction or changing of the stimulus energy

Did you know that fishing dates back to around 40‚000 BC? Fishing has been around for a long time and has drastically changed over the years. In this speech I will tell you about the history of fishing‚ the history of the fishing rod and reel‚ and how fishing has changed over the years. The first way people fished was with a spear which was also called a harpoon. This kind of fishing is thousands of years old. The spear would have been made out of a stick that was sharpened or barbed. The fisherman
