Investigation Definition and 120 Threads

Fire investigation, sometimes referred to as origin and cause investigation, is the analysis of fire-related incidents. After firefighters extinguish a fire, an investigation is launched to determine the origin and cause of the fire or explosion. Investigations of such incidents require a systematic approach and knowledge of basic fire science.

    I just wanted to say i retire from physics investigation

    my objective was to achieve free energy and reactionless propulsion to heal the world and colonize other planets to ensure the future of the human race after 5 years research i get to the conclusion that things like the water engine are very real and working but they are kept secret by the...

    Exploring Magnetism: Tips for Conducting a Physics Investigation

    Hi, I'm doing an investigation in physics - magnetism, to be specific - and basically I'm takin 1 or 2 bar magnets, and a hall probe, and placing the magnets at different distances from the probe, and different angles to see the variation in magnetic field strength. However, I need to extend it...

    Higher Gravity Environment Investigation

    I'm currently working on designing some type of experiment on which to write an in-depth essay. My idea currently is pretty general, but it basically creating a centrifuge-like model that includes a chamber in which the higher g's would be experienced, with a human within it. The idea is for...

    What is the mechanism of action of methicillin and novobiocin?

    Hello. I am doing an investigation on antibiotics. Does anyone know what the exact mechanism of action does methicillin follow? I tried to look for this on google but unfortunately all I can find is MRSA... I think Methicillin has same mode of action as Penicillin G (interfering with cell wall...

    Investigation into how sound proofing actually works

    Hey everyone I'm doing some investigation into how sound proofing actually works, and I'm more or less stuck. I've found two terms(http://www.soundproofing101.com) which are used to decribe what happens when you sound proof. they are: noise reduction and noise absorbtion "Noise reduction...

    How Does Orifice Diameter Affect Fluid Flow Rate?

    (Thanks to the guy who answered my original thread) For a physics project I'm investigating the effects on the flow rate of fluids. I'm going to find a relationship between orifice diameter and flow rate (keeping things simple I'll assume it's a circular orifice for a cylindrical can). For...

    Waves Investigation [Using water]

    hi in my physics class right now we've been told we're going to be to doing an experiment where we put a variable amount of water into a tray, hold one side up, and drop it from a variable height, thus, when it hits the table, the water will move and waves will ocsillate back and fourth...

    Pendulum investigation with a stop

    I did this experiment with various values for (d), which is the height from the top of the string to the stop. The length of the string was 0.7m. Since i used 6 differnt values for (d) i got 6 readings. why i stated all this is because i have to find g from the following expression T =...
