assume the driver originally established neutral buoyancy at one depth to establish neutral buoyancy at a lower depth the diver should
(a)let some air out of the vest
B add some air to the vest

do nothing because neutral buoyancy already exist

At lower depth the Buoyancey force would be more sue to the indiscriminant difference in pressure hence he needs to add some air to the vest to rise the pressure differnece and to maintain the neutral Buoyancy force.

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.

An object of mass m = 0.25 kg oscillates in a fluid at the end of a vertical spring of spring
constant kH = 85 N/m, see Fig.1. The effect of the fluid resistance is governed by the
damping constant b = 0.07kg/s.
(i) Find the period of the damped oscillation.
(ii) By what percentage does the amplitude of the oscillation decrease in each cycle?
