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

value of the reaction order the larger the effect of that specie’s concentration on the rate of the reaction. So for the chemical equation for this experiment: The reaction rate is: . Due to the fact that alcohol is found in excess in this reaction it can be removed from the expression‚ leaving the expression: Beers Law states that the amount of light absorbed is proportional to the concentration of a species‚ in this case (3). Where A is the measure of absorbance. Ԑ is the molar absorptivity

Physical Light and Spiritual Light In this discussion‚ there are two kinds of light that are going to be compared. The two kinds of lights that are going to be compared against each other in this discussion are going to be; physical light and spiritual light. As we all know‚ the sun‚ stars‚ oil lamps will all eventually burn out‚ whereas the light of God is forever‚ so showing that spiritual light‚ God’s light‚ is much better than physical light. In Genesis 1:3 God said let there be light and there

interaction Milgram’s experiment is to study the effect of obedience to authority. Study was performed to determine what factors influenced people to submit to authority and to what extent people conform an order against their conscience despite knowing it causes distress and harm to another person. McLeod‚ S. (1970). 40 male participants between age of 20 to 50 years old from various occupation ranging from unskilled to professional were recruited for the experiment. They were rewarded $4.50

Are you looking for a fun experiment that you can perform for a psychology class? This experiment on gender and memory is relatively quick and easy to perform‚ which is a bonus if you are short on time and resources. Could gender differences play a role in short-term memory? We often hear women complain that their husbands can’t remember important dates like anniversaries or birthdays‚ but could this phenomenon be due to something like memory differences between men and women. Some previous research

Relevant to: 2.5.2. Describe photosynthesis in terms of inputs‚ outputs and energy transformations. Criteria to be assessed: PL‚ DCP‚ DEC. Background: Photosynthesis is the reaction carried out by green plants to produce a supply of food. The reactions occur in the chloroplasts and require light energy. 6CO2 + 6H2O C6H12O6 + 6O2 In aquatic plants‚ the production of oxygen can be used to measure the rate of photosynthesis as the oxygen bubbles can

the speed of light “So far as problems involving light are concerned‚ the electrons (in atoms) behave as though they were held by springs”.Feynman “In a microscopic but otherwise classical analysis‚ the electric field in electromagnetic radiation accelerates electrons held by springs in the atoms of a piece of glass‚ and these accelerated electrons re-radiate in all directions. The observed light is the superposition of the electric (and magnetic) fields of the incoming light and the re-radiation

Osmosis Lab Report The essential focus of the experiment was to acquire data for the mass change resulting from osmosis in order to determine the carbohydrate solution of the carrot cells. The carrots were a vegetable used within the experiment with a carbohydrate solution around .5 M. The hypothesis is if there are carrots in different carbohydrate solutions then there will be a percent change in mass. The carrots have large vacuoles that hold water‚ this allows the mass to increase when the hypertonic

The milgram experiment. The three people involved were: the one running the experiment‚ the subject of the experiment a volunteer‚ and a person pretending to be a volunteer. These three persons fill three distinct roles: the Experimenter an authoritative role‚ the Teacher a role intended to obey the orders of the Experimenter‚ and the Learner the recipient of stimulus from the Teacher. The subject and the actor both drew slips of paper to determine their roles‚ but unknown to the subject‚ both slips
