When temperature of a gas is 20°C and pressure is changed from P₁ = 1.01*10⁵ Pa to P₂ =1.165 * 10⁵ Pa then the volume changed by 10%.The bulk modulus is

(a) 1.55 * 10⁵ Pa

(b) 0.115 * 10⁵ Pa

(c) 1.4 * 10⁵ Pa

(d) 1.01 * 10⁵ Pa

Three identical balls are placed on a frictionless horizontal surface touching each other. They stick to each other because of adhesive. Another ball of same radius and mass m is placed over the void created by the three balls. Find the forces applied by the balls kept on the floor to each other if the system remains in equilibrium.

A car loaded with water having total mass 1000 kg moves on a straight horizontal Road starting from rest under the action of a force of 100 Newton. The water spills throw a small hole in the bottom at a rate of 0.1 KG per second the velocity of cart after 300 seconds is nearly.
