this experiment is to investigate the various aspects of harmonic motion using a Driven Harmonic Motion Analyser (DHMA). The aspects that are investigated in this experiment is the spring constant k of two springs‚ the resonant frequency‚ the damping factor‚ and the relationship between phase and resonant frequency. The value of k of the first string by calculating the mean is (12.51 ± 0.001) N/m and the value of k by using linear regression is (12.7 ± 0.3) N/m. The value of k of the second string

The Experiment Gloria Isham Central Texas College Twenty- six men are chosen to participate in the roles of guards and prisoners in a psychological study led by a Doctor Archaleta for which each participant is to receive $14‚000 after two weeks. Travis has just lost his part time job and is a peace protester who wants to travel to India with his girlfriend. Barris is a 42-year-old who lives alone with a domineering mother‚ who has made him join the experiment to raise money for her hip operation

EXPERIMENT 1: REACTIONS OF ENOLATE IONS WITH CARBONYL GROUPS Aims In this experiment we used two techniques for the reactions of enolate ions with carbonyl groups. One technique used was Doebner reaction and the other technique used was Claisen-Schmidt reaction. Therefore the aim of this experiment is to synthesize trans p-methoxycinnamic acid and to synthesize dibenzalacetone via an aldol condensation reaction between acetone and benzaldehyde. The products would be recrystallized using ethanol

Biography of a Mathematician: Sir Isaac Newton Sir Isaac Newton has made an impact on scientists to this day. Even though his discoveries derived in the late 1600s‚ we are still affected today in the present. The ideals and theorems he sought out still hold legitimate centuries after his time. With the information laid out for them‚ a scientists using his theories can improve their research to achieve fame themselves. “Some would say that he was the greatest product of the Enlightenment‚ the

Experiment 2: IDENTIFICATION OF UNKNOWNS BY TLC AND MP IN COMBINATION Introduction: Thin layer chromatography (TLC) is one of the most valuable techniques in organic chemistry. This is a best method of separating and identifying mixtures of two or more compounds. The separation is accomplished by the distribution of the mixture between two phases: one that is stationary and one that is moving or mobile. Chromatography works on the principle that different compounds will have different

All About Vertical Motion! Hey! I know the vertical motion model can be hard‚ but once you get the hang of it‚ it’s a piece of cake. Math is all about using your prior knowledge‚ plugging it into what you know‚ to solve for what you don’t know. The vertical motion model is made up of the velocity‚ and height. The equation is -16t2 + vt + h. V is equivalent to the velocity‚ and h is equal to the height. The vertical motion falls under the influence of gravity. As the

process of distillation. Distillation is the separation of volatile substances mixed with nonvolatile substances by boiling the mixture to alter the phase of the volatile substance. The researchers used the simple distillation set up to conduct the experiment. 25 ml of The Bar Vodka was used and 7 ml of distillate was collected before a temperature of 95 degrees Celsius was reached. Collected distillate was then subjected to a flammability test to confirm ethanol content. The percent ethanol was computed

Newton’s second law of physics dictates that acceleration is produced when a force acts on a mass. The greater the mass of the object‚ the greater the force needed to put the object in an accelerated motion. This relationship can be viewed in the formula: Force = mass (acceleration) The key to keeping the mousetrap car accelerating is to keep the forces acting upon it unbalanced. The force of the mousetrap car has to be larger than the force of friction working against the car. Because the force
