Find the thickness of the wire The main scale division is of 1mm In a complete rotation the screw advances by 1mm and the circular scale has 100 devisions

While measuring length of an object it was observed that the zero of the vernier lies between 1.4 and 1.5 of the main scale and the fifth division coincides with a main scale division. If the length of the object measured is l, then the value of (l-1.4) in terms of the least count C of the instrument is:

The hydrolyiss of methyl acetate in aqueous solution is has been studied by titrating the liberated acetic acid against NaOH . The concentration of ester at different times is given below: |{:("t (min)",0,30,60,90),(C (Mol L^(-1)),0.8500,0.8004,0.7538,0.7096):}| Show that it follows a pseudo first order reaction, as the concentration of water remains nearly constant (55 mol L^(-1)) during the course of the reaction . What is the value of k' in the equation ? Rate = k'[CH_(3)COOCH_(3)][H_(2)O]
