Physics of a Light Bulb Catherine Bellet Lab Partners: Natalie Russell Alex Harris TA: Chad Lunceford PHY 114 TH @ 2:25pm Abstract: Ohm’s law states‚ via the equation V=I*R‚ that the voltage found across a piece of material is proportional to the current. If the temperature remains constant therefore the resistance is found to remain constant. Stefan-Boltzmann law states that when the temperature if above an average of 1000K‚ then the relationship of voltage and current should be found

In optics‚ corpuscular theory of light‚ originally set forward by Pierre Gassendi‚ states that light is made up of small discrete particles called "corpuscles" (little particles) which travel in a straight line with a finite velocity and possess kinetic energy. It was largely developed by Sir Isaac Newton. Newton’s theory remained in force for more than 100 years and took precedence overHuygens’ wave front theory‚ partly because of Newton’s great prestige. However when the corpuscular theory failed

Light Dependent Reactions The light dependent reaction of photosynthesis involves the transfer of sunlight energy into two things: The production of ATP Reduction of coenzyme NADP to NADPH NADP – Nicotinamide adenine dinucleotide phosphate NADPH – Reduced NADP The energy from sunlight is used to excite an electron‚ within a primary pigment‚ to a higher energy level. The excited electron is then donated to an electron acceptor leaving the chlorophyll molecule oxidised and reducing the acceptor

Inversion‚ repetition‚ balance and climax. The poem relates an incident which occurred during the Crimean war in 1854. England‚ France and Turkey fought the Russian forces.

the ways in which laws and social policies affect family life Currently‚ in the UK‚ the family is a fairly unregulated sphere of life‚ compared with different societies such as China. Laws and social policies in Britain today tend to encourage or discourage certain types of families‚ rather than actively enforcing them like China’s one child policy. Government agencies and institutions only seem to take an active role on policing areas of family life when things are perceived to have gone wrong
