and dirty secrets of a twisted mind‚ a serial killer stalking his prey in the subway. And Duncan can’t stop reading. What would you do with a book like that? How far would you go to catch a madman? This is the teaser to an amazing book I read “Acceleration” By: Graham McNamee. Duncan the main leading character of the story discovers a journal belonging to what he thinks is a serial killer and he uses his knowledge of profiling as well as the clues from the journal to try to decipher who the serial

the Concept Yes‚ there are forces acting on it. They are the normal force of the table and the gravitational pull of Earth (weight). Because the cup is not accelerating relative to the ground‚ the forces are the same as those that would act on it if it was sitting on your table at home. 2 • You are passing another car on a r highway and determine that‚ relative to you‚ the car you pass has an acceleration a to the west. However‚ the driver of the other car is maintaining a constant speed and direction

Determination of the Acceleration Due to Gravity By A Good Student Abstract The acceleration due to gravity‚ g‚ was determined by dropping a metal bearing and measuring the free-fall time with a pendulum of known period. The measured value is 9.706 m/s2 with a standard deviation of 0.0317‚ which does not fall within the range of known terrestrial values. Centrifugal forces and altitude variations cannot account for the discrepancy. The calculation is very sensitive to the measured drop

Scientific question: How does the incline of a slope influence the acceleration of a cart when it travels down a wooden plank? Introduction: What is an incline plane? Commonly referred to as a ramp or a slope‚ an incline plane is an even surface that is titled at an angle. An object placed on the tilted surface will often slide down the surface‚ accelerating because of an unbalanced force. The rate at which an object travels down the slope is dependent upon how tilted the slope is; the greater

completion of this laboratory activity‚ the student should be able to use the pressure probe to carry out experiments with gases. determine the relationship between the pressure and the volume of a gas. Background This experiment will draw upon your experience with computer-based laboratory methods from previous lab activities utilizing the computer. In the first part of the experiment‚ you will see how changes in volume affect the pressure of a gas. In the bonus part‚ you will have the opportunity

Discussion and Conclusion: Preparation of 1-Bromobutane The purpose of this experiment was to demonstrate the conversion of a primary alcohol‚ 1-butanol‚ to a primary bromoalkane‚ 1-bromobutane‚ a SN2 reaction. The conversion of 1-butanol to 1-bromobutane relies on sulfuric acid which plays two important roles. First‚ it protonates the alcohol of 1-butanol to form an oxonium ion which is a good leaving group. Secondly‚ it produces the hydrobromic acid‚ the nucleophile‚ which attacks 1-butanol

One day he discovers an unmarked journal with no name‚ which depicts sadistic animal torture experiments‚ boasts of arson fires‚ and the planning for the serial killings of three women. Duncan decides to make amends for his failure last summer by tracking down the owner of the journal by using clues left hidden in the diary. After talking with
