    Biology; Chemistry; Physics: Post your doubts here!

    We use gamma only,cuz its the only one that can penetrate through the skin easily. Using the formula H=mc(delta) 5.2X1000=5200=2x20x (X) Divide 5200 by 40 we get 130 so C is the answer In calibration we use 2 fixed points that are 0 C and 100C

    We can place the barriers one by one and if it passes the aluminium and a count rate higher than background is registered we can say it is gammao_O

    That minus the formula,is the exact definition,rate of flow of charge.

    Guys current is simply rate of flow of electric charge which we can see by its formula I=Q/t

    Biology; Chemistry; Physics: Post your doubts here!

    Ok we take the volume as relative moles e.g 4 moles of Oxygen,1 mole of the hydrocarbon and so on As the equation for combustion is always ending with H20 + CO2 we can check how many carbon atoms the hydrocarbon would have by checking the moles of CO2 which was 3.And then by forming the rest of...
