A force of 5 N gives a mass \(M_1\) an acceleration equal to \(8 \, \text{m/s}^2\) and \(M_2\) an acceleration equal to \(24 \, \text{m/s}^2\). What is the acceleration, if both masses are tied together?

A fireman weighing \(80\,\text{kg}\) slides down a pole. If the resisting force of friction is \(720\,\text{N}\), his acceleration would be: (take \( g = 10\,\text{m/s}^2 \))

A 4 kg block A is placed on the top of a block B of mass 8 kg, which rests on a smooth table. A just slips on B when a force of 12 N is applied on A. Then, the maximum horizontal force required to make both A and B move together is:

The ratio of the speed of an object to the speed of its real image of magnification \(m\) of a convex mirror is

Three blocks of masses \( m_1, m_2 \) are connected by massless strings as shown on a frictionless table. They are pulled with a force \( T_3 = 40 \, \text{N} \). If \( m_1 = 10 \, \text{kg} \), \( m_2 = 6 \, \text{kg} \), and \( m_3 = 4 \, \text{kg} \), the tension \( T_2 \) will be:

Vapour pressure of pure 'A' is 70 mm of Hg at $25^{\circ}C$. It forms an ideal solution with 'B' in which mole fraction of A is 0.8. If the vapour pressure of the solution is 84 mm of Hg at $25^{\circ}C$, the vapour pressure of pure 'B' at $25^{\circ}C$ is

Three equal masses M are placed at the vertices A, B, and C of an equilateral triangle. The net force acting on a unit mass placed at the centroid O is:
