Fear or exitement, generally cause one to breath rapidly and it results in the decrease of {tex}CO_2{/tex} concentration in blood. In what way will it change the pH of blood?
Two identical balls A and B collide head on elastically. If the velocity of A and B before collision are 0.5 m/s and -0.3m/s respectively, then their velocities after collision will be
If for a plane, the intercepts on the co-ordinate axes are 8, 4, 4 then the length of the perpendicular from the origin on to the plane is
The area (in square unit) enclosed by the curve y = 4 x3 and y = 16x is
In Young's double slit experiment, the width of one of the slits is slowly increased to make it twice the width of the other slit. Then in the interference pattern:
