Kinetic theory

Arrhenius’ constant = Activation Energy RT = Average kinetic energy (Universal gas constant × Temperature in Kelvins) In this experiment, the main focus is placed on the Arrhenius plot, which is derived through the manipulation of the Arrhenius equation to remove its exponential form by taking the natural log of both sides of the equation which forms lnk=lnA-E_A/RT A

Pictorial drawing will also be provided on a selected section of one of the braking systems being compared. Introduction: Bicycle Braking systems are a means of which we are able to halt the movement of a bicycle through the expulsion of kinetic energy. The Kinetic potential energy that is present in a moving bicycle is

High school is fun when you get to know the different types of people there. If you don’t, you get confused and frustrated because you meet all these different types of people, and you can’t find the ones you have things in common with. No worries! I am here to help. I have provided a guide that will give you the attributes of the different types of high school students and help you to quickly identify them. When I got into high school, it took me a while to put majority of these students into

the amount of kinetic energy a ball possess after collision. The ball that is travelling down the ramp with a slightly higher angle, will possess more kinetic energy before collision but after collision it will posses less kinetic energy because of it being an elastic collision where energy is conserved and transfers some energy to the ball travelling down the less steep ramp with less momentum. Therefore the ball travelling down the ramp that is not as steep will possess more kinetic energy after

Racing at a solid 1.4m fence at speeds of almost 25 km/hr, the only way to get around this fence is to trust that the horse will listen to every command; trust that the horse won’t run out, or refuse, he will simply put all of his trust into his rider to guide him safely to a takeoff distance that will be perfect. In a matter of seconds, but horse and rider will be up and over the fence and racing to the next line. Although many may not consider the sport of equestrian as a physics problem, it is

The regulation of essential biological processes such as metabolism, growth and reproduction is a hallmark of living systems. Cells, the fundamental units of life, employ a variety of mechanisms to achieve this exquisite control, and regulation of the activity of proteins provides a means to fine-tune cellular processes. One of the ways of controlling the activity of proteins is to alter the absolute levels of a protein in a cell. This is achieved either by altering the levels of the mRNA coding

A Regenerative Braking System Using ‘KERS’ a device used to recover, otherwise wasted energy. I. Abstract -Kinetic Energy Recovery System or simply ‘KERS’ is a system developed to recover a modest amount of energy during braking of an automobile or a locomotive. This system tries to harvest energy which is otherwise wasted. KERS works on the principle of Regenerative Braking, which uses the braking energy to rotate a flywheel connected to the differential( in an automobile) through a gear mechanism

In order to find the velocity of the ball and the pendulum just after the collision we will use the principle of conservation of energy. Neglecting friction at the point of support of the pendulum, the gravitational potential energy must equal the kinetic energy of the ball and the pendulum at the bottom of the

Relative Reactivity of Alkyl Halides in Nucleophilic Substitution Reactions Charlie Doyle Madison McGough Annie Chang   Introduction Both Sn1 and Sn2 reactions are nucleophilic substitution reactions, though they are slightly different. Sn2 reactions have bimolecular displacement and are also concerted, meaning the bond making and the bond breaking processes happen in one step.1 Sn1 reactions require two steps and have unimolecular displacement. This difference can be seen
