The Speed of Toy Cars & Measuring Acceleration Introduction: The Speed of Toy Cars & Measuring Acceleration was investigated by using a ticker timer and changing the angle of the ramp. Changing the angle of the ramp affects the speed and acceleration of the trolley. The speed and acceleration of the trolley was determined by using the ticker timer. Aim: The aim of the practical is to investigate the motion and acceleration of a trolley by using a ticker timer and rolling the trolley down a ramp

Measuring Crime CJA/204 October 9‚ 2013 Richard Pacheco Measuring Crime There are two different instruments used in reporting crime. There are also major crimes reporting program used in the United States. These major crime reporting programs do have a purpose and does give statistical information on crime in the United States. There are a difference between crime rates‚ arrest rates‚ clearance rates‚ and recidivism rates. The information reported about crime rates can be misleading and give

TITLE Basic Technologies of Handling Chemicals and Laboratory Apparatus INTRODUCTION Density is defined as mass per unit volume. The commonly used unit to indicate the density of water is (g/cm3). Water never has an absolute density because its density varies with temperature. Water has its maximum density of 1 g/cm3 at 4oC. When the temperature changes from either greater or less than 4oC‚ the density will become less than 1g/cm3 only when it is pure water. Other factors that

Dated: 12-04-2013 STEPS INVOLVED IN THE SELECTION FLOW METER There are well over 20 different types of flow meters‚ even if we lump the various positive-displacement flow meters together as one type. Unless the process engineer knows the pros and cons of each type‚ it can be a daunting task to properly select one. Here are just some of the factors to consider before selecting a flow meter: • Its size and measuring range of the flow meter • Chemical compatibility • Process accuracy requirements•

Criminal Justice Paper Zugeily Estrada CJA 204 June 5‚ 2014 Linda Fisher - Lewis Criminal Justice System Criminals have existed through out centuries. Some people will only commit a single petty criminal act in their lifetime while some people will be chronic criminal offenders. While criminals are sometimes involved in simple petty theft‚ others are involved in more serious violent acts such as battery‚ sexual assault‚ and death. Crime is considered to compromise

Quiz. Evaluate the following problems. Show your solution and encircle your final answer. 1. In a 25-kVA‚ 2000/200 V‚ single phase transformer‚ the iron and full load copper losses are 350 W and 400 W respectively. Calculate the efficiency at unity power factor on a) full load‚ b) half full-load. 2. If P1 and P2 be the iron and copper losses of the transformer on full load‚ find the ratio of p1 and P2 such tat maximum efficiency occurs at 75% full load. 3. A 5-kVA‚ 2300/230 V‚ 50 Hz transformer

Measuring Brain Activity Most of the noninvasive imaging methods estimate brain activity by changes in blood flow‚ oxygen consumption‚ glucose utilization‚ etc. Discuss the potential problems with using this type of indirect measure. The brain is the control center of the human body. It sends and receives millions of signals every second‚ day and night‚ in the form of hormones‚ nerve impulses‚ and chemical messengers. This exchange of information makes us move‚ eat‚ sleep‚ and think.
