In the circuit below, A and B represent two inputs and C represents the output.
The circuit represents
A student measuring the focal length of convex lens by putting an object pin at a distance 'u' from the lens and measuring the distance 'v' of the image pin. The graph between 'u' and 'v' plotted by the student should look like
A thin rod of length 'L' is lying along the x-axis with its ends at x=0andx=L. Its linear density (mass/length) varies with x as k(Lx)n, where n can be zero or any positive number. If the position xCM of the centre of mass of the rod is plotted against 'n', which of the following graph best approximates the dependence of xCM on n ?
If P and Q are the points of intersection of the circles x2+y2+3x+7y+2p5=0and x2+y2+2x+2yp2=0, then there is a circle passingthrough P, Q and (1,1)for
On the basis of the following thermochemical data : (ΔfG2H(aq)+=0)
If one of the lines of my2+(1−m2)xy−mx2=0is a bisector of the angle between the lines xy=0, then m is
