What types of evidence can be collected at a crime scene? Samples That May be Collected at a Crime Scene biological evidence (e.g., blood, body fluids, hair and other tissues) latent print evidence (e.g., fingerprints, palm prints, foot prints) footwear and tire track evidence. trace evidence (e.g., fibers, soil, vegetation, glass fragments) What are the […]
What is the use of strain gauge?
What is the use of strain gauge? A strain gauge is a type of electrical sensor. It’s primary use is to measure force or strain. The resistance of a strain gauge changes when force is applied and this change will give a different electrical output. Strain gauges use this method to measure pressure, force, weight […]
What does scanning the road mean?
What does scanning the road mean? total traffic scene When scanning you should be looking ahead down the road? In order to avoid last minute moves and spot possible traffic hazards, you should always look down the road ahead of your vehicle. When you are looking far enough ahead in your travel path, you will […]
What are the applications of expert system?
What are the applications of expert system? Application areas include classification, diagnosis, monitoring, process control, design, scheduling and planning, and generation of options. What are the stages in the development of expert system tools? Waterman [11] provided five phases/stages approach in the development of Expert System: Identification , Conceptualization, Formalization, Implementation, and Testing. What is […]
How do compact fluorescent light bulbs save energy?
How do compact fluorescent light bulbs save energy? Because CFLs use less electricity than traditional light bulbs, they reduce demand for electricity; that reduction means less greenhouse gas emissions (including less mercury) from power plants. CFLs contain a very small amount of mercury — an average of 4 milligrams in each bulb. What is the […]
How does drag coefficient vary with Reynolds number?
How does drag coefficient vary with Reynolds number? As the Reynolds number is increased, the form drag increases relative to the skin fric- tion. Beyond a Reynolds number of 1000, the skin friction is negligible. Between Re = 1000 and Re = 200000, the point of separation remains very near the equator so the drag […]

What evidence indicates that a reaction has occurred select all that apply? Potential signs that chemical reactions have occurred include a change in color, change in temperature, formation of a gas, and formation of a precipitate. What evidence indicates that a chemical change has occurred? Some signs of a chemical change are a change in […]

How does boundary layer separation occurs?
How does boundary layer separation occurs? The phenomenon is termed as separation of boundary layer. Separation takes place due to excessive momentum loss near the wall in a boundary layer trying to move downstream against increasing pressure, i.e., , which is called adverse pressure gradient. What do you mean by boundary layer? Boundary layer, in […]
What is a system in signals and systems?
What is a system in signals and systems? A system is any process that produces an output signal in response to an input signal. Continuous systems input and output continuous signals, such as in analog electronics. Discrete systems input and output discrete signals, such as computer programs that manipulate the values stored in arrays. What […]
