The given dimensional formula matches with that of force. Force = mass x acceleration.

A simple dimensional equation uses three basic parameters – mass, length and time. Hence the maximum number of unknowns that can be found is 3.

The dimensions of acceleration are LT^-2. On doubling both length and time, the new dimensions become (0.5)*LT^-2.

An empirical formula is the simplest whole number ratio of various atoms present in a compound. The molecular formula is the exact number of different types of atoms present in the molecule of a compound.

The molecular formula is the exact number of different types of atoms present in the molecule of a compound. An empirical formula is the simplest whole number ratio of various atoms present in a compound. Therefore we can calculate the molecular formula if the molar mass is known.

the molecular formula of glucose is C₆H₁₂O₆. The ratio in the molecular formula is 6:12:6; carbon, hydrogen, and oxygen respectively. So by simplifying them into simpler whole numbers, we obtain 1:2:1.

Aristotle classified the organisms based on their morphological characteristics. His classification neglected characteristics like nature of the cell wall, evolutionary relationships and method of reproduction.

Aristotle classified plants based on their size into herbs (Wheat, Paddy, etc.), shrubs (Rose, Jasmine, etc.) and trees (Banyan, Banana, etc.). He classified animals based on their blood.

Aristotle’s classification contained two kingdoms i.e. Plants and Animals. Plants are sub-divided into herbs, shrubs and tree. Animals are further sub-divided into red blooded and non- red blooded animals.

Aristotle classified the organisms into Plants and Animals whereas Carolus Linnaeus classified the organisms into Plantae and Animalia. Whittaker’s 5 kingdom classification contained Monera, Protista, Fungi, Plantae and Animalia.
