problems involving ratio

Ratio is the numerical relationship between two quantities of the same kind. The first quantity is called the antecedent and the second quantity is called the consequent. By performing simple operations on ratios, we get compounded ratio, duplicate ratio..

Ratio is the numerical relation of one quantity to another of the same kind. To find the ratio of 2 m 25 cm to 75 cm, we first change 2 m 25 cm into cm, which equals 225 cm. Now, we have to find 225 cm to 75 cm ratio is = 3 : 1 We can write the above ratio as..

Processes Involved in Transport - There are some physical principles and biological processes that explain the transport of materials across the plant body. They are as follo..

It is a physical process that involves the movement of solute particles from the region of their higher concentration to the region of their lower concentratio..

It is a physical process that involves the movement of solute particles from the region of their higher concentration to the region of their lower concentration. Transport of materials within the cell is by diffusion. The entry of carbon dioxide into the stomata is by diffusio..

Equilibrium Involving Physical Changes - Substances exist in three states: solids, liquids and gases. The following types of equilibriums exist in three state..

It is so called as it takes place only in the presence of sunlight and hence is a light-dependent reaction. Robin Hill, an English biochemist conducted studies on isolated chloroplasts to understand the mechanism of light reaction..

In reversible reactions chemical reactions take place in both the forward and backward directions. For example, the reaction between gaseous hydrogen and iodine vapours to give gaseous hydrogen iodide is a reversible reaction and may be expressed as: In this reaction, the products cannot combine to..
