A stream of electrons from a heated filament was passed between two charged plates kept at a potential difference V esu. If e and m are charge and mass of an electron, respectively, then the value of h / λ (where λ is wavelength associated with electron wave) is given by :

The integral∫2x12+5x9(x5+x3+1)3 dx is equal to :

Two sides of a rhombus are along the lines, x – y + 1 = 0 and 7x – y  5 = 0. If its diagonals intersect at (–1, – 2), then which one of the following is a vertex of this rhombus?

Let a- ,b- and c-  be three unit vectors such that a-×b-×c-=32b-+c- if c- is not parallel to is c- , then the angle between a- and ,b- is:

A person trying to lose weight by burning fat lifts a mass of 10 kg upto a height of 1 m 1000 times. Assume that the potential energy lost each time he lowers the mass is dissipated. How much fat will he use up considering the work done only when the weight is lifted up? Fat supplies 3.8 X 10 7 J of energy per kg which is converted to mechanical energy with a 20 % efficiency rate. Take g = 9.8 ms-2 :
