Visual Perception Pictorial depth cues are what we use to create depth and distance on a 2D canvas or paper. Linear perspective is used when two parallel lines converge together and are perceived to come to a point into the distance. We perceive this in straight roads‚ railway tracks or hallways. This image displays linear perspective on the left side on the box as it is perceived to come together despite the fact that the lines are parallel. Interposition is used when an object sits in front

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

ROTATIONAL MOTION CENTRE OF MASS AND ROTATIONAL MOTION INTRODUCTION- For describing the motion of rigid bodies‚ we shall introduce the key concept of ‘centre of mass’. This concept enables us to understand how we can apply justifiably the Newton’s laws of motion‚ in essentially the same form to objects of large size including even the astronomical objects like the planets and the stars. KINDS OF MOTION OF A RIGID BODY- A rigid body may have three kinds of motion- (1) Pure Translation Motion- in such

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

Edgar Xiong David Blackburn Period 3 Physics of Flight One may wonder‚ what is flight? Many just stare up into the blue skies above and assume. while others devote their lives to discovering and finding a passion in aviation. Flight can be simply characterized as the [powered] gliding of an object through the air‚ but the wonders of soaring through the air does not simply stop there‚ instead‚ flight is a whole myriad of forces acting on each other‚ as so found out by scientists decades

Kyle Brooks 11/13/12 Angry Birds Projectile Motion Lab How to Perfect Distances Of Birds using Launching Angles Purpose: The Purpose of this Lab is to discover which launch angles give the birds the longest and shortest time in flight. Hypothesis: I believe that the bird will launch the farthest at the 45 degree angle because that’s exactly half of 90 degrees which will give it the maximum height in comparison to length. I also think that the bird will launch the shortest at 0 degrees

AP Physics HW #1 Multiple Choice 1. A car travels 30 miles at an average speed of 60 miles per hour and then 30 miles at an average speed of 30 miles per hour. The average speed the car over the 60 miles is (A) 35 m.p.h. (B) 40 m.p.h. (C) 45 m.p.h. (D) 10 m.p.h. (E) 53 m.p.h. Answer: B. Method: Vavg = Δx/Δt The average speed is the total distance traveled‚ divided by the total time. They give us all distances traveled is‚ so we just need to find the time. We find the time‚ by applying

Independent Assessment Physics Lab (SL): Cantilever Flexion Cherno Okafor Mr. Ebrahimi SPH4U7 October 21st‚ 2012 Introduction Purpose: The purpose of this Physics Lab is to investigate what factors determine the amount of flexion of the cantilever. Hence‚ the objective is to establish a relationship between the length of a cantilever‚ which may give some insight into the physics of cantilevers. Hypothesis: If one increases the length of a cantilever‚ one would expect there to be an
