    Tonicity is a measure of the effective osmotic pressure gradient; the water potential of two solutions separated by a semipermeable cell membrane. In other words, tonicity is the relative concentration of solutes dissolved in solution which determine the direction and extent of diffusion.

    Mass, in physics, quantitative measure of inertia, a fundamental property of all matter. It is, in effect, the resistance that a body of matter offers to a change in its speed or position upon the application of a force. The greater the mass of a body, the smaller the change produced by an applied force.

    The third law of motion states that when one object exerts a force on another object, the second object instantaneously exerts a force back on the first. These two forces are always equal in magnitude but opposite in direction. These forces act on different objects and never on the same object.

    Action and Reaction First an action occurs—Jerod pushes against the ground with his foot. Then a reaction occurs—the ground pushes back on Jerod! This force causes Jerod to move forward. The reaction is always equal in strength to the action but in the opposite direction.

    Avg speed of entire trip - V and total distance d=60Km and total time taken is t. Avg speed in first 30Km _ v1=30Kmh-1 and time taken to cover it is t1. Avg speed in last 30Km _ v2=? and time taken to cover it is t2. V = d/t V = 60/(t1+t2) V = 60/[(30/v1)+(30/v2)] 40 = 60/[(30/30)+(30/v2)] (30/30)+(30/v2) = 60/40 = 1.5 1 + (30/v2) = 1.5 30/v2 =0.5 v2 = 30/0.5 v2 = 60 Kmh-1

    Solids lack the property of diffusion because the particles in the solids are closely arranged leaving very little inter molecular space. he particles of the solids have less inter-molecular spaces between them which does not allow free movement of particles. The particles can only move about their mean position.
