- Joule, unit of work or energy in the International System of Units (SI); it is equal to the work done by a force of one newton acting through one metre.
- Watt is a SI unit of power which is defined as the energy per unit time
- In simple terms, an electrical conductor is defined as materials that allow electricity to flow through them easily. This property of conductors that allow them to conduct electricity is known as conductivity.
- Myopia, Also Called Near sightedness, is a eye defect in which the patients are not able to see objects at long distances clearly. Persons who are myopic, has their eye lens maximum value decreased.
- Resistance is a property of conductor due to which it resists the flow of electric current through it.

Italy was divided into smaller kingdoms namely Sardinia, Lombardy, Venetia and Sicily. Among these, Sardinia was the most powerful one. The Papal states, comprising Rome and Central Italy were under the Pope.Cavour was able to annex the kingdoms of Parma, Lombardy, Modena, Tuscany and parts of the Papal states in 1859. A bold sailor called Giuseppe Garibaldi annexed the rest of the territories of Naples. Venetia, which was under Austria was ceded to Italy by Austria in 1866 when Austria was weakened by the Prussian war. Rome refused to become part of the Italian state. In 1870, Prussia attacked France and the Pope stopped getting support from the French king. Rome was forcibly entered into and occupied by the Italians. Finally, the state of Italy emerged as an independent nation state in 1871 with Victor Emmanuel as the king.

We know that,
sec A = 1/cos A
⇒ cos A = 1/sec A
cos²A + sin²A = 1
⇒ sin²A = 1 – cos²A
⇒ sin²A = 1 – (1/sec²A) (cosA= 1/secA)
⇒ sin²A = (sec²A-1)/sec²A
⇒sinA = √((sec²A-1)/sec²A)
⇒sinA = √(sec²A-1) ÷ (secA)............................(i)
sin A = 1/cosec A
⇒ cosec A = 1/sin A
⇒cosecA= secA ÷√sec²A-1 (from eq i)
Now,
sec²A – tan²A = 1
⇒ tan²A = sec²A + 1
⇒tanA = √sec²A + 1.....................................(ii)
tan A = 1/cot A
⇒ cot A = 1/tan A
⇒cotA = 1/√sec²A + 1 (from eq ii)

Answer:
'Utopian vision' means that it is depicting something idealistic. The French artist F Sorrieu was visualizing a dream of a world made up of nations (all of them did not exist as nations at the time that these prints were made). He has showed the German people with a common flag, although actually they were a number of different states at that time. So it is an idealistic or Utopian vision.

The two boys followed muddy footprints being made fresh without seeing anybody making the prints, which was a 'mystery' for them. The explanation was that the bewildered boys had been following a scientist who had just discovered how to make the human body transparent, and thus invisible, by swallowing certain drugs.

The steps to be taken to minimize environmental degradation by industry are:
Minimizing water pollution:
1. Minimizing use water for processing by reusing and recycling it in two or more successive stages.
2. Harvesting of rainwater to meet water requirements.
3. Treating hot water and effluents before releasing them in rivers and ponds.
4. Treatment of industrial effluents done in three phases:
a. Primary treatment by mechanical means. This involves screening, grinding, flocculation and sedimentation.
b. Secondary treatment by biological process.
c. Tertiary treatment by biological, chemical and physical processes. This involves recycling of wastewater.
5. Overdrawing of ground water reserves by industry where there is a threat of ground water resources also needs to be regulated legally.
Minimizing air pollution:
1. Particulate matter in the air can be reduced by fitting smoke stacks to factories with electrostatic precipitators, fabric filters, scrubbers and inertial separators.
2. Smoke can be reduced by using oil or gas instead of coal in factories.
Minimizing noise pollution:
1. Machinery and equipment can be used and generators should be fitted with silencers.
2. Almost all machineries can be redesigned to increase energy efficiency and reduce noise.
3. Noise absorbing materials may be used apart from personal use of earplugs and earphones.

Agriculture and industry are not exclusive of each other. They move hand in hand.
(i) The agro-based industries have given a major boost to agriculture by raising its productivity.
(ii) The agro-based industries depend on agriculture for raw materials and sell their products such as fertilisers, insecticides, irrigation pumps, PVC pipes, machines and tools, etc to the farmers.
(iii) Thus, development and competitiveness of manufacturing industry has not only assisted agriculturists in increasing their production but also made production process very efficient.

Structure of a Nephrons:
- Nephrons are the basic filtering units of kidneys.
- Each kidney possesses large number of nephrons, approximately 1-1.5 million.
- The main components of the nephron are glomerulus, Bowman’s capsule, and a long renal tubule.
Functioning of a Nephron:
- The blood enters the kidney through the renal artery, which branches into many capillaries associated with glomerulus.
- The water and solute are transferred to the nephron at Bowman’s capsule.
- In the proximal tubule, some substances such as amino acids, glucose, and salts are selectively reabsorbed and unwanted molecules are added in the urine.
- The filtrate then moves down into the loop of Henle, where more water is absorbed.
- From here, the filtrate moves upwards into the distal tubule and finally to the collecting duct. Collecting duct collects urine from many nephrons.
- The urine formed in each kidney enters a long tube called ureter. From ureter, it gets transported to the urinary bladder and then into the urethra.

The deterioration of the quality of land is known as land degradation. Mining anddeforestation have deteriorated the quality of land in Chhattisgarh, Madhya Pradesh, Jharkhand and Odisha. Overgrazing is one of the main reasons for the land degradation in Gujarat, Rajasthan, Maharashtra and Madhya Pradesh. In Punjab, Haryana and western Uttar Pradesh, excess irrigation has resulted in water logging leading to increased soil salinity. In major metropolitan cities, industrial effluents have degraded the land.
- Afforestation
- Proper management of grazing and wastelands
- Control on unrestricted mining
