Some reasons that a homicide investigation starts at the primary crime scene is mainly because the police are usually called to this location by the person who discovers the body‚ or‚ a witness to the crime‚ but it could also in some cases even be the victim. In homicide cases‚ the location where the body is discovered hold a great deal of physical evidence and serves as a starting point for the beginning of an official investigation.

examples of work done=force x distance What is work? Work in physics is the transfer of energy; work is done on an object when an applied force moves it through a distance. The link between work and energy is work done equals energy transferred. The units for the two are also the same (joules). E.g. 500J of work = 500J of kinetic energy. Work is calculated with the formula: work done=force x distance moved For example‚ if a force of 10 newton (F = 10 N) acts along point that travels 2 meters

Experiment title: Preparation of Biological Materials for Microscopic Examination Objectives: 1. To learn how to use a microscope. 2. To study the cell structure of starch grains‚ onion cells and cheek cells. 3. To differentiate the difference between starch grains‚ onion cells and cheek cells. Introduction: Microscope is an optical instrument use to magnify micro objects that hardly or impossible to be observed by naked eyes‚ so that the objects can be studied. Compound light microscope

power an iPod with a Gatorade-soaked onion doesn’t work. Many Internet users today have made the same discovery after viewing the video in question‚ produced by the Web site HouseholdHacker.com. First‚ let’s examine the idea of powering any electronic device with a fruit or vegetable. The concept is believable because you can create a battery with a few potatoes. This experiment is a science class favorite because it helps demonstrate how the galvanic cells that make up a car battery work.
