Consider the following standard electrode potentials (E° in volts) in aqueous solution :
Based on these data, which of the following statements is correct ?
The amplitude of a damped oscillator decreases to 0.9 times its original magnitude is 5s. In another 10s it will decrease to α times its original magnitude, where α equals.
Let A and B be two sets containing 2 elements and 4 elements respectively. The number of subsets of A×Bhaving 3 or more elements is
Two charges, each equal to q, are kept at x = ?a and x = a on the x-axis. A particle of mass m and charge q0=2q is placed at the origin. If charge q0 is given a small displacement (y a) along the y-axis, the net force acting on the particle is proportional to:
A beam of unpolarised light of intensity I0 is passed through a polaroid A and then through another polaroid B which is oriented so that its principal plane makes an angle of 45∘ relative to that of A. The intensity of the emergent light is:
The standard Gibbs energy change at 300 K for the reaction 2A⇔B+C is 2494.2J. At a given time, the composition of the reaction mixture is [A]=21,[B]=2and[C]=21. The reaction proceeds in the :
The distance of the point (1, 0, 2) from the point of intersection of the line 3x−2=4y+1=12z−2and the plane x y + z = 16, is :
