Hazards of Static Electricity; Lightning Lightning is a massive electrostatic discharge between the electrically charged regions within clouds or between a cloud and the surface of a planet. It is the sudden high-current discharge caused by the atmosphere’s electrical breakdown. Lightning is also one of the most deadly natural phenomena known to man. Lightning is an electric current; thus within a thundercloud up in the sky‚ many small bits of ice (frozen raindrops) collide into each other as

coordination‚ increased mobility‚ and curiosity and these accidents are the cause of more deaths than all childhood diseases (Edelman & Mandle‚ 2010). The most common accidental injuries are structural hazards‚ drowning‚ burns‚ poisoning‚ and motor vehicle accidents (Edelman & Mandle). • Structural hazards include staircases‚ tabletops‚ chairs‚ and playground equipment‚ which toddlers can fall from. Safety gaits should be used to block access to stairs‚ chairs should be placed away from countertops and

abusive towards them‚ which is also known as another form of bullying. Education: Michael hardly spent a lot of time going to a regular school‚ as he was always tutored at home. Although he does have the vague memories of when he did go to school‚ also how he was the teachers’ favourite student‚ this was the only place he loved because people did not love his stories because of his name‚ but because of the talent he had in art and English. Jackson has always loved singing and dancing but more than that

A fire occurred in a transformer vault that supplied power to a pesticide storage warehouse. The warehouse also caught fire. The warehouse was located in a rural area. There was a river adjacent to the warehouse that was the source of drinking water for a town downstream of the warehouse. The chemical products that were used in the transformer and the chemicals that were stored in the warehouse were all industrial strength and were supposed to be handled with extreme caution. All of these chemicals

I am a movie fanatic. When friends want to know what picture won the Oscar in 1980 or who played the police chief in Jaws‚ they ask me. My friends‚ though‚ have stopped asking me if I want to go out to the movies. The problems in getting to the theater‚ the theater itself‚ and the behavior of some patrons are all reasons why I often wait for a movie to show up on TV. First of all‚ just getting to the theater presents difficulties. Leaving a home equipped with a TV and a video recorder isn’t an

A graded potential in physiology‚ is described as local changes in membrane potential that occur in varying grades or degrees of magnitude or strength. When compared to graded potential‚ an action potential is described as brief‚ rapid‚ large (100mV) changes in membrane potential during which the potential actually reverses so that the inside of the excitable cell transiently becomes more positive than the outside. As with a graded potential‚ an action potential involves only a small portion of

which cell has the larger resting membrane potential? Explain. If the permeability to K is higher in A than in B‚ then the resting membrane potential (rmp) will be closer to the equilibrium potential in cell A‚ which means the rmp will be more negative in cell A than in cell B; or in other words‚ the potential difference will be LARGER in cell A. 2. Predict the effect of a reduced extracellular concentration of Na+ on the magnitude of the action potential in an electrically excitable cell. If there

The formation of an action potential can be divided into five steps. (1) A stimulus from a sensory cell or another neuron causes the target cell to depolarize toward the threshold potential. (2) If the threshold of excitation is reached‚ all Na+ channels open and the membrane depolarizes. (3) At the peak action potential‚ K+ channels open and K+ begins to leave the cell. At the same time‚ Na+ channels close. (4) The membrane becomes hyperpolarized as K+ ions continue to leave the cell. The
