The height at which the acceleration due to gravity becomes $9g $ (where g = the accleeration due to gravity on the surface of the earth) in terms of R, the radius of the earth is

Consider a family of circles which are passing through the point $(−1,1)$and are tangent to x-axis. If (h, k) are the co-ordinates of the centre of the circles, then the set of values of k is given by the interval

Knowing that the Chemsitry of lanthanoids (Ln) is dominated by its +3 oxidation state, which of the following statements in incorrect ?

The area of the plane region bounded by the curves $x+2y_{2}=0$and $x+3y_{2}=1$is equal to

A body is at rest at x = 0. At t = 0, it starts moving in the positive x-direction with a constant acceleration. At the same instant another body passes through x = 0 moving in the positive x-direction with a constant speed. The position of the first body is given by \displaystyle{x}_{}

While measuring the speed of sound by performing a resonance column experiment, a student gets the first resonance condition at a column length of 18 cm during winter. Repeating the same experiment during summer, she measure the column length to be x cm for the second resonance. Then

The quadratic equations $x_{2}-6x+a=0andx_{2}-cx+6=0$have one root in common. The other rootsof the first and second equations are integers in the ratio 4 : 3. Then the common root is
