Interpretation Introduction

(a)

Interpretation:

To determine density of wood.

Concept introduction:

Archimedes’ principle states that a body which is at rest and placed in a fluid in such a manner that when it is submerged completely or partially then a buoyant force will act in the upward direction whose magnitude will be equal to the weight of displaced fluid.

As surrounding fluid is of uniform density so, the weight of displaced fluid is equal to the volume of the displaced fluid. It concludes that the mass of displaced fluid is equal to mass of object immersed in the fluid. The object immersed in fluid in this case is the cylinder. So, mass of displaced fluid is equal to mass of the cylinder.

Interpretation Introduction

(b)

Interpretation:

To determine the liquid density.

Concept introduction:

Archimedes’ principle states that a body which is at rest and placed in a fluid in such a manner that when it is submerged completely or partially then a buoyant force will act in the upward direction whose magnitude will be equal to the weight of displaced fluid.

As surrounding fluid is of uniform density so, the weight of displaced fluid is equal to the volume of the displaced fluid. It concludes that the mass of displaced fluid is equal to mass of object immersed in the fluid. The object immersed in fluid in this case is the cylinder. So, mass of displaced fluid is equal to mass of the cylinder.

Interpretation Introduction

(c)

Interpretation:

To explain why knowing length and width of the wooden object is unnecessary
