What is the total magnification if we using objective lens 4x and our eyepiece (ocular) lens is 10x 40x
100x
400x
1000x

Answercanyon;

Answer:             1.0  × 10⁻⁵ msolution:                     as we know ph is given as,                                    ph  = -log [h⁺]and,                                    [h⁺]  =  10^-ph    (1)putting value of ph in eq. 1,                                    [h⁺]  =  10⁻⁵                                    [h⁺]  =  1.0  × 10⁻⁵ m

This question is rather vague, but i will try and answers it as best i can.start by being polite, then complement on the attributes that you like about that person. be friendly to her friends. don't be mean to anybody she knows, even if you really don't like them. be yourself, don't try to impress, just be yourself and hope that she likes you.
