Fifty Questions 1. What two entities comprise a vector?-a vector is comprised of direction and magnitude. 2. What do you do with any vector that is not on either the x or y axis?-break it up into x and y components using trig‚ add up the components. 3. How are velocity and speed different?-velocity has a direction while speed does not. 4. What is the slope of the distance time graph? - Delta d/delta t. or distance over time. Rise over run. 5. What is acceleration?-increase

INTRODUCTION INTRODUCTION TO INTELLECT SPEED BREAKER USING CAN PROTOCOL This project deals with limiting the speed of the vehicle by employing technology of embedded systems using “Peripheral Interface Controller (PIC 16F877A)”‚ when the vehicle enters the speed limiting zone. The parameter to be controlled in this project is speed. PIC has the advantage of enhanced FLASH memory with the modified Harvard architecture and having simple 35 instructions. A Controller Area Network (CAN)

Maintaing the speed limit as it is will be more effective than to lower the speed limit for various reasons. Reasons such as it will make less traffic‚ keep drivers focused‚ and allow people to get to their destinations faster. Also making the speed limit higher will force cars that drive on highways and interstates to be more reliable and better maintenance. This will lower break downs onn high ways and interstates because people will think twice before they drive their irreliable vehicle on the

INVESTIGATING THE EFFECT OF TEMPERATURE ON THE RATE OF ENZYME ACTIVITY. To investigate the effect that temperature has on enzyme activity I am going to use the enzyme amylase‚ which is used as a biological catalyst to break down starch‚ which cannot pass through the gut wall due to the size of the molecules‚ into smaller ones. Amylase is a carbohydrase‚ which converts starch to simple sugars in the Salivary Glands. Three features of all enzymes are: They are always proteins. They are specific

Should drinking age be increased to 21. It is no secret‚ that people drink alcohol before they turn 21. Stories about drinking on college campuses and high school parties are very easy to find. That is why underage drinking can be stopped if the law were changed. The major reason that people drink at an early age is because they feel it is fun and exciting to do something they are not supposed to. However‚ if it would be lowered to 18‚ then the trill of doing something illegal would vanish

ASSIGNMENT 1 What Happen the Petrol Price Decrease in the Ends of 2008 and its Effect on Consumers and Suppliers. Petrol is a petroleum-derived liquid mixture‚ primarily used as fuel in internal combustion engines. It also is used as a powerful solvent much like acetone. Petrol is very important in our life. Most current or former Commonwealth countries use the term "petrol"‚ abbreviated from petroleum spirit. In North America‚ the word "gasoline" is the common term‚ where it is often

nothing but a small particle. The big bang was a big explosion which now we call the universe‚ it expanded quickly throughout the years. About 300‚000 years went by and that’s when the universe started to cool down. There was two types of particles at that point matter and antimatter when they were close to each other they would destroy each other. The universe started to filled with hydrogen and helium gas. Scientists never discovered what was before the big bang. So no one knows what was before it.

Time‚ Speed and Distance 1. If a car starts from A towards B with some velocity. Due to some problem in the engine after traveling 30km‚ the car goes with (4/5)th of its actual velocity. The car reaches B 45 minutes later than the actual time. If the car engine had failed after traveling 45km more‚ the car would have reached the destination (B) 36minutes later than the actual time. What is the initial velocity of the car in km/hr? (a) 60 (b) 77 (c) 75 (d) None of these 2. A and B are two

The Trojan War The Trojan War was a very important part of the Greeks’ history. There are many myths and legends about the trojan War. In the Iliad‚ it describes certain events in the final year of the war. According to legend‚ the Trojan War lasted 10 years‚ until Greece defeated Troy. Many of ancient Greek stories talk about the Trojan War‚ particularly Homer’s Iliad and the Odyssey. Many scholars believe the legend is based on a real war of the mid-1200’s B.C.’s. People have

Concentration‚ pH and Temperature on Enzyme Activity Biology For Majors October 4‚ 2012 Abstract We examined the reaction an enzyme has when its concentration‚ pH and temperature are altered. In order to do this‚ we added different levels of pH into different test tubes with the enzyme (sucrose)‚ and substrate (sucrose)‚ and we then inverted the tube. The higher pH produced more enzyme activity. Temperature effects enzyme activity by decreasing its stability when the temperature increases. Oppositely
