2 m/s‚ what is the kinetic energy of the entire system? KETOT = KEwheel+KEweight = (1/2)(I)(w2)+(1/2)(m*v2) =(0.5* v2)(m+1/2M) =0.5*(2.2^2)*(3+(.5*15)) J b) If the system started from rest‚ how far has the weight fallen? H = KETOT/MG = 0.5*(2.2^2)*(3+(.5*15))/(3*9.8) m c) What is the angular acceleration at this point? Remember that a = αR‚ or α = a/R Solve for acceleration by using vf2=vi2+2ax (vf=2.2

The Effect Of Enzyme Concentration On Enzyme Activity The pancreatic duct in individuals who have cystic fibrosis frequently becomes blocked‚ reducing or preventing the release of pancreatic enzymes into the small intestine. The aim of this activity is to investigate the effect of a reduction in enzyme concentration on the rate of reaction‚ in this case the breakdown of protein by protease enzymes. Aim – Milk powder contains a white protein called casein. A white suspension of

Kinetics of an SN1 reaction: the effect of solvent on rate Object The purpose of this experiment is to determine the rate of hydrolysis in acetone/water (50/50 v/v and 60/40 v/v). Background and Theory An SN1 reaction of tert-butyl chloride takes place in two steps. First‚ the Alkyl Halide will leave the molecule. In this step the bond is breaking‚ which takes a longer amount of time‚ so it will determine the rate of the reaction. As a result‚ it forms a tertiary carbocation‚ since this

Introduction How does changing the surroundings of enzymes affect their reaction rate? The purpose of the experiment is to determine how different abiotic conditions affect the rate at which enzymes accelerate/cause reactions In this lab students measured the height of the foam after catalysis between catalase (enzyme) and 7 other (solutions) to determine which solution had the fastest reaction rate.. The control variable of the experiment would be the solution of only hydrogen peroxide‚ water

Jessica Hearing Purpose of Experiment- To guess how many different noises we can recognize without using vision. Hypothesis- If I make noise with my objects‚ then I will be able to recognize the sound even without seeing them Experimental Procedure: 1. First‚ I will begin by getting everything I need such as coins‚ a jar‚ a hard back book‚ and paper. 2.

What effect does temperature have on the oxygen production of enzymes in an animal’s liver? A temperature which is too high would be able to produce little to no oxygen because of the extreme temperature. Just like a temperature too high‚ a temperature which is too low would also produce little to no oxygen for the same reason. Animals that have livers are considered warm-blooded‚ with very warm temperatures; therefore it would make sense for a warm temperature to produce the most oxygen; but one

Name: Tan Tee Hng Class: MB1102 Module: Molecular Genetics Date: 6th January 2013 Circadian Rhythms From this experiment‚ using transgenic fly that can glow in the dark‚ a study of circadian rhythms was performed. Circadian Rhythm is like an internal body clock(biological clock) of an animal. And results obtained from experiment conducted with transgenic glowing fly‚ allowed one to come up with a few hypotheses‚ firstly‚ circadian rhythm repeats every 24 hours. When the glowing flies were placed

Enzyme Inhibition Many drugs exert their action by inhibition of an enzyme activity in the body. If the activity of an enzyme is vital to the cell or organism‚ then inhibition may lead to death of the cell or organism. It is now possible to design new drugs which are enzyme inhibitors once a target enzyme has been identified. Types of Inhibitors A) Reversible Inhibitors: The effect of the inhibitor is instantaneous‚ and it can be removed from the enzyme by dialysis so that the enzyme activity

The two different types of energy are kinetic and potential energy. Kinetic energy is the energy a moving object has because of its motion. The kinetic energy of a moving object depends on the object’s mass and its speed. The kinetic energy of a moving object can be calculated from this equation: Kinetic energy (in joules) = ½ mass (in kg) x [speed (in m/s)]² KE= ½ mv² In this equation ^‚ the symbol v represents speed. Example Find the kinetic energy of the ball having mass 0‚5 kg and

Static and Kinetic Friction Introduction The amount of friction force between two surfaces in contact depends on the type of the surfaces in contact and the amount of compression between the surfaces. Static friction is the force that is acting against your force before the object begins to move. If you exert a small push on the box‚ the box will not move because static friction is directly opposite to the push. If you apply a greater force than the static friction force‚ the friction increases
