Answer:
Laws of Floatation
A body floats in a liquid if:
1. Density of the material of the body is less than or equal to the density of the liquid.
2. If density of material of body is equal to density of liquid, the body floats fully submerged in liquid in neutral equilibrium.
3. When body floats in neutral equilibrium, the weight of the body is equal to the weight of displaced liquid.
4. The centre of gravity of the body and centre of gravity of the displaced liquid should be in one vertical line.
Now, we will understand Centre of Buoyancy and Meta Centre
Centre of Buoyancy: The centre of gravity of the liquid displaced by a body is known as centre of buoyancy.
Meta centre: When a floating body is slightly tilted from equilibrium position, the centre of buoyancy shifts. The point at which the vertical line passing through the new position of centre of buoyancy meets with the initial line is called meta centre.
hope it helps dear.
Explanation:
Velocity of the body changes continuously in uniform circular motion. It is continually shifting its direction when an object travels around a circle. Accelerating objects – either the velocity (i.e. the magnitude of the velocity vector) or the direction are objects which change their velocity.
