The length of an elastic string is a metre, when the longitudinal tension is 4 N and the length is $b$ m, when the tension is 5 N. When the longitudinal tension is 9 N, the length of the string (in metre) is

On a particular day, the maximum frequency reflected from the ionosphere is 9 MHz. On another day, it was found to increase by 1 MHz. What is the ratio of the maximum electron densities of the ionosphere on the two days?

A man standing on the road has to hold his umbrella at 30 degrees from the vertical direction to keep the rain away. He thrown away the umbrella and starts running at ${10\, km \, h^{-1}}$, he finds that the rain drops are hitting him vertically. The speed of the rain drops w.r.t. the road is

A projectile is fired vertically upwards from the surface of the Earth with a velocity $k\upsilon _e$ , where $\upsilon_e$ is the escape velocity and $k < 1$ . If $R$ is the radius of the Earth, the maximum height to which it will rise measured from the centre of the Earth will be

Structure of a mixed oxide is cubic close packed $(ccp)$. The cubic unit cell of mixed oxide is composed of oxide ions. One fourth of the tetrahedral voids are occupied by divalent metal A. The octahedral voids are occupied by a monovalent metal B. The formula of the oxide is

The coagulation of 200 mL of a positive colloid took place when 0.73 g HCl was added to it without changing the volume much. The flocculation value of HCl for the colloid is
