For claiming credit for discovering 104^th element, the Americans named it Rutherfordium and the Soviets named it Kurchatovium. While it’s named Unnilquadium as per IUPAC nomenclature. Neptunium is the 93^rd element.

As per the notations of the IUPAC nomenclature, the 101^st element is named as Unnilunium. When the Einstenium was bombarded with alpha particles, Mendelevium was discovered and named after Dmitri Mendeleev.

As per IuPAC nomenclature of periodic elements greater than 100, Un means 1, nil means 0 and oct means 8, so the element numbered 108 is unniloctium. It’s chemical names is Hassium and is represented by the symbol “Hs”. It is highly radioactive in nature and man made.

Instantaneous velocity describes the velocity of an object at a given time instant. Average speed is the speed at which the object travels throughout the time period and not an instant. Speed is a scalar quantity; hence it cannot show the direction of motion.

The function for velocity can be derived by differentiating the equation with respect to t. v = 2(t-4) is the required function. When t = 5, v = 2(5-4) = 2.

The instantaneous velocity will increase with time. If the motion is accelerated, no matter if the acceleration is constant, or variable, the instantaneous velocity will increase. Variation of acceleration describes how to change in velocity is changing.

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.

Linnaeus classified amoeba under Animalia. His classification didn’t consider cell structure, nature of the cell wall, mode of reproduction, evolutionary relationships which resulted amoeba in Animalia.
