    CAREER COUNSELLING

    I am currently doing my A levels. A2 to be exact with engineering subjects. In AS I got Chem B, Phy B, Math A. I really love the three subjects and I don't know what to do in the future. I know its going to be engineering, which I am not sure of. Help.

    The balls P and Q didnt attract each other which means they had the same charges. As P is Negative thus Q will also be negative. As for R it is attracted to ball Q. Ball Q being negative will only attract positive or a neutral ball. As the choices don't state any choice about it being neutral...

    Because when dilute ammonia aqueous is used dropwise the NH3 not being a stronger base than the OH- cant take part in the reaction. As dilute ammonia aqueous means. NH3 + 2 H2O -----> NH4+ + 2 OH- The OH being the stronger one when dil NH3 is used in little amount reacts with Ni to displace...

    The gas that will be liberated will be H2 in each case. So the substance Q should be the salt of a metal which is below H in the reactivity series so that H can reduce it. And it would be Cu. For the metal P reaction to occur between it and dilute sulfuric acid it should be a reactive metal thus...

    Structure isnt required doesnt mean you dont have to study about the process of ultrafiltration and rest. And yes on the safe side the structure should be studied.

    The mass doesn't matter when the scale is balanced. the torque is zero the anticlockwise moment is equal to the clockwise moment so mass isn't of concern anymore when the scale is balanced.

    Take the weights of measuring cylinder and the initial block of wood as zero because these two balance each other that will make the calculation simple and actually will have a solution. Now, 0.39 x (40/100) = W x (30/100) solve for W and you will have the weight asked. For the next part W=mg...

    The answer is D. It is because the work done he puts to go forward is actually equal to the work he does against the resisting forces. As he is moving at a constant speed the work done is actually equal. So the heat lost is the work he is doing to move forward.
