We know, magnitude of displacement is the straight line distance between the initial and final point of the path of a moving body.
Displacement can be positive, negative or zero.
While distance travelled is always positive or zero when there is no motion.
So the ratio of displacement to distance is always equal to or less than 1.

Answer:
In binomial nomenclature, name of every organism is composed of two components—the first one is generic (genus) and the second one is specific (species). Also, the generic name starts with a capital letter whereas the specific name starts with small letter. For example, the scientific name of man is “Homo sapiens”. Here “Homo” is the generic and “sapiens” is the specific name.

(a)
ANSWER
Displacement is the shortest distance travelled from the initial point to the final point. After half revolution the displacement is the length of the diameter which is equal to 2r. Hence the displacement is 2r.

The decrease in the quantity of ozone in the upper layer of the atmosphere is called depletion of ozone. This is also known as the ozone hole. Due to this hole, ultraviolet rays of the Sun can reach the Earth and cause diseases such as skin cancer.
Pollutants such as oxides of nitrogen, chlorine free radicals etc. are produced in the atmosphere. Molecules of ozone react with these pollutants and are destroyed. This causes depletion of the ozone layer.

The phenomenon of change of solid directly to gas or conversion of gas directly to liquid without changing into liquid state is called sublimation. For instance, camphor also called capoor when kept for a long time vanishes. This is due to the sublimation of camphor.

The Haversian canal contains small blood vessels responsible for the blood supply to osteocytes (individual bone cells). A Haversian canal and its lamellae and osteocytes form a Haversian system. The lamellae between Haversian system is called as interstitial lamellae. The Haversian canals are interconnected by transverse channels termed as the Volkmann's canals. Haversian systems are absent in spongy bones of mammals.

- As the object covers equal distances in equal intervals of time, it is said to be in uniform motion.
Example- Motion of planets around Sun, they revolve at a constant speed. So the distance travelled in every equal time period is equal

The representation of a chemical reaction in the form of substances is known as a chemical equation. The equation in which the number of atoms of all the molecules is equal on both sides of the equation is known as a balanced chemical equation.
Law of conservation of mass governs the balancing of a chemical equation. According to this law, mass can neither be created nor be destroyed in a chemical reaction and obeying this law total mass of the elements or molecules present on the reactant side should be equal to the total mass of elements or molecules present on the product side. If the chemical equation is not balanced law of conservation is not applicable.

The kilowatt-hour (symbolized kWh) is a unit of energy equivalent to one kilowatt (1kW) of power expended for one hour (1h) of time. The kilowatt-hour is not a standard unit in any formal system, but it is commonly used in electrical applications. Kilowatt - hour is the commercial unit of electrical energy. We have seen that power is the rate of energy consumed or delivered. If 1 joule of energy is used per second, we say that energy is used at the rate of 1 watt. A kilowatt hour (kWh) is a measure of how much energy you're using. It is simply a unit of measurement that equals the amount of energy you would use if you kept a 1,000 watt appliance running for an hour: So if you switched on a 100 watt light bulb, it would take 10 hours to rack up 1 kWh of energy.
