    oxygen-sensitive meter

    ive got its an electrochemical cell (galvanic) with pT and Ag eletrodes in KCl; all in a porous plastic membrane filter. Oxygen diffuses through the pores into the KCl and electrolysis takes place and amount(electrolysis) is directly proportional to concentration oxygen. Is the electrolysis the...

    y=2sinx help

    so you cant tell its an odd function from the equation and just be like hey its odd itll cancel out to make 0? or do we draw the graph, see it has a POINT of axis of symetry around the x axis and is therefore odd? so as the side to the left of the curve is beneath and not above then we declare...

    y=2sinx help

    this was part ii. part i was to evalute the integral y=2sinx between -pi<=x<=pi (answer was 0) and part ii was to evalute the area between the curve and the x axis without integrating. so jw why 4x(from 0-pi/2) gave us the answer aka how we found the area without integrating at all. and why...

    y=2sinx help

    Sketch y=2sinx for -pi<=x<=pi without integrating, evaluate the area bounded by the curve y=2sinx for -pi<=x<=pi and the x axis so the answers did from 0 to pi/2 and multiplied by 4. how come we dont do the 2xintegral(0-pi)? because i dont understand why we can do this without an integral if we...

The answers to a question had fire optics because of the 2km distance and interference etc. But a farm wouldnt be able to afford these as its like 30,000 a kilometer or something. Would you use common sense...

    validity...etc

    experiment: place a raw chicken bone in a sample of each of acid, water, fire; to remove calcium to test the flexibility of bones after these conditions have taken affect on the raw bones. Accuracy: as it is not quantitative is there no accuracy to this? or would it be measuring the exact volume...
