The diagram below shows the electrolysis of dilute sulphuric acid. Hydrogen is formed at the negative electrode (cathode) and oxygen at the positive electrode (anode) and the concentration of sulphuric acid increases. (5) The ions present in the dilute acid are H+ (aq), OH- (aq) and SO4 2- (aq). (i) Write an equation for the reaction at the negative electrode (cathode). (ii) Write an equation for the reaction at the positive electrode (anode) (iii) In the apparatus used in above figure, the power supply is removed and immediately replaced by a voltmeter. (3) Reading on the voltmeter shows that electrical energy is being produced. How has the electrical energy been produced?

Step-by-step explanation:

Sum of all angles of triangle is 180°

So, let the angle MOL be x

= 70 + 20 + x = 180

= 90 +x = 180

= x = 180 -90

= x = 90°

therefore, angle MON is equal to 90°

Now,angle MON is also equal to angle PON

hence, angle PON = 90°

Sum of all angles of triangle is 180°

So, let the angle NPO be x

= 90 + 70 + x = 180

= 160 + x = 180

= x = 180 - 160

= x= 20°

hence, angle NPO is equal to 20°

Answer:

In ΔLMO

∠L+ ∠M+ ∠O =180°

∠O+ 90° =180°

∠LON = 90°

∠PON = 90°

In ΔPON

∠P+ ∠O+ ∠N=180°

∠P+ 160=180°

∠P = 20°

Answer:

Agra is an old city situated on the banks of river Yamuna. It is mentioned in ancient literature. It is a city of beautiful historical buildings. There are many Mughal buildings here. The buildings of Fatehpur Sikri were built by Akbar. Moti Masjid and Taj Mahal were built by Shah Jahan. The fort of Agra was also built by Akbar. It is said that earlier there was another fort at this place. The Taj Mahal here is a great wonder of the world. Agra is now an industrial city. Millions of people from many countries of the world come here to see the Taj Mahal.

Question) Describe the beliefs and practices of the Nathpanthis, Siddhas and Yogis.​

Answer) Nathpanthis, Siddhas, and Yogis advocated renunciation (altruism) and trained that the way to salvation was through reflection on the shapeless Ultimate Reality and the unity of the human spirit with it. They preached exceptional preparation of the psyche and body through yoga asanas, breathing exercises, and contemplation. These gatherings were mainstream among the 'low' stations and their analysis for the regular Vedic religion made a base for another religion to turn into a typical force in the north.
