Let vector C = vector A + vector B. (a) | vector C | is always greater than | vector A |

(a) –ΔG0 = RTlnK. Thus, if ΔG0 is less than zero, i.e., it is –ve and hence K will be greater than 1.  (b) Under ordinary conditions, the average energy of...

(c) either metals or non-metals 

Correct answer is (D) always a non-zero number

(b) It is possible to have I CI < I A > I and IC|< IB I

(b) The electromagnetic force between two protons is always greater than the gravitational force between them.  (c) The gravitational force between two protons may be greater than the nuclear force between...

(b) The luminous efficiency of a monochromatic source of wavelength 555 nm is always greater than that of a white light source of same power. (c) The illuminating power of a...

(b) equal to AB (c) less than AB  (d) equal to zero. Explanation: The magnitude of the vector product of two vectors A and B may be less than or equal to AB, or...

Thanks mam And big thanks to this app that solves most of the jee question

(d) A = x2 – y2 = (x + y)(x – y) = 10 (x – y) B = 20 Now, it is not possible to compare A and B, as...
