Three critics review a book. For the three critics the odds in favor of the book are \(2: 5, 3: 4\) and \(4: 3\) respectively. The probability that the majority is in favor of the book, is given by

A body is released from the top of a tower '\(\mathrm{H}\)' metre high. It takes \(t\) second to reach the ground. The height of the body \(\frac{t}{2}\) second after release is

Identify degenerate orbitals from following for hydrogen atom.

The p.d.f. of a discrete random variable is defined as \(\mathrm{f}(x)=\left\{\begin{array}{l} \[\mathrm{k} x^2, 0 \leq x \leq 6 \\\] 0, \text { otherwise } \[\end{array}\right.\)\]

Then the value of \(F(4)\) (c.d.f) is

A body of mass 200 gram is tied to a spring of spring constant \(12.5 \mathrm{~N} / \mathrm{m}\), while other end of spring is fixed at point '\(O\)'. If the body moves about '\(O\)' in a circular path on a smooth horizontal surface with constant angular speed \(5 \mathrm{~rad} / \mathrm{s}\) then the ratio of extension in the spring to its natural length will be
