Spokane‚ Washington. Viney and Fenton (1998) defined the term electrophoresis as‚ “the migration of charged particles through a static medium under the action of an applied electric field (p. 576). Just from this definition‚ it is clear that numerous physics concepts can be used to help explain why electrophoresis works. First‚ I will discuss charge and electric fields and how these principles are utilized in gel electrophoresis. This will be followed by a

the most due to the deaths caused by air pollution. Michael Graham Richard reports that 3.5 million deaths are caused by indoor air pollution and 3.3 million deaths are caused due to outdoor pollution. This essay will be discussing the use of electrostatic precipitator in reduction of air pollution. In total number of deaths are 6.8 million‚ this results are twice as many deaths as previously thought. According to BBC News in recent years‚ carbon dioxide emission have become a serious environmental

For Lab 1‚ my partner and I will be demonstrating the law in which connects the period of the pendulum‚ expressed as T‚ to the length of the string‚ expressed a L. The system the lab will be based on will include a pendulum with a weight of W suspended at a fixed point by the string with a variable length of L and an angle theta to be measured using a protractor. The variable T will be measured as the period of time needed for the weight of the pendulum to swing back and forth once. For part 1 of

In the Tumble Buggy Lab‚ my partners and I used several different methods to calculate the velocity of a Tumble Buggy. The methods we used were a meter stick and a timer‚ a Spark Timer‚ a Photogate‚ and a Motion Sensor. Each method was different but overall‚ our velocities were very similar. Using the meter stick and timer‚ our velocity was 0.22 m/s. With the spark timer‚ our velocity was 0.26 m/s. Next‚ the velocity found with the Photogate was 0.325 m/s. Finally‚ when we used the motion sensor

Experiment 7: Relative Density Laboratory Report Marella Dela Cruz‚ Janrho Dellosa‚ Arran Enriquez‚ Alyssa Estrella‚ Zacharie Fuentes Department of Math and Physics College of Science‚ University of Santo Tomas España‚ Manila Philippines Abstract The experiment was conducted to show the different methods on how to determine an object’s composition through its density and to determine an object’s density by displacement method and the Archimedes Principle. Results show that. The materials

Abstract :The purpose of the experiment is to explore elastic and inelastic collisions in order to study the conservation of momentum and energy. The guided track‚ carts‚ photogates ‚ 250 g weight and picket fences were the primary components used in the procedural part of the experiment. Each experiment involved the use of the photogates and picket fences to measure the initial and final velocities of both carts when they collide. The data was collected and translated to a graphical model for further

My lab results were similar to my hypothesis. My hypothesis was that the densest object would be the rubber stopper. In the lab results the densest object was the penny and the rubber stopper was second. My hypothesis was switched. My hypothesis was correct when I stated that the macaroni was the third densest object. My hypothesis was also correct for the dice‚ but the bead and the dice share the same density. So they are both the fourth densest item. I was wrong with my hypothesis when I placed

LAB # 5 Relationship Between Drop Height and Diameter of Plasticine Sphere PROBLEM: A student suggest that there is a proportional relationship between height at which a plasticine sphere is dropped and the diameter of the flattened part after dropping. Design an experiment to determine if this suggestion is true or not. AIM: To investigate the relationship between the drop height and the flattened part of a plasticine sphere after being dropped. HYPOTHESIS: As the height of the sphere plasticine
