a capillary tube of 1.2mm diameter is immersed vertically in water container exposed to atmosphere . find how high water will rise in the tube . take contact angle of the inner wall of the tube to be 6 degress and surface tension to be 1 n/m take densiyu of water as 1000kg/m^3

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.
