• In Ro-Ro (Roll-on, Roll-off) transport, the trucks loaded with goods are transported to desired railway stations through a goods train.
• From there the trucks take the goods ahead to the desired locations. 
• Ro-Ro transport helps to reduce the cost of transport as railways are used for the part of the distance. 
• Ro-Ro transport also reduces cost of fuel and pollution caused by trucks.

Due to mountains, valleys, rivers, reservoirs

1. remote sensing – obtaining information regarding any place or an object without actually establishing direct contact with it is called remote sensing. 

2. physiography – nature and slope of land and undulating topography a region becomes devoid of any transport route.

Ro-Ro transport is Roll-on, Roll-off transport.

Freight transport by trucks is costlier than railways, so as a solution the Ro-Ro transport has been introduced.

BHIM App, SBI Anywhere app, helps us to pay various bills, sell, buy and carry out various transactions through mobile phones.

Crimes like website/email hacking, theft of information, economic frauds, wars, terrorism, etc. that are committed by using computers and internet are called ‘cyber crimes’.

Physical transferability: When goods can be actually transferred from one person to another and from one place to another place it has physical transferability. E.g. Motor Car, Furniture, Machinery, etc.

Notional transferability: When goods cannot be actually transferred physically it has notional transferability. E.g. Land, Building, etc.

26th December 2004.

The brave and ever – ready Arjuna responded quickly. He set an arrow to his bow, shot it into the stream aiming at the right point. It infused the crocodile and drove it away but it did not hit the Guru’s foot.

When the Guru Dronacharya asked Yudhistira what he saw on the tree, Yudhistira replied that he could see the tree, the bird, his brothers, other friends and everything.

Kautilya was a great statesman, philosopher, economist, and royal advisor during the Mourya period. He is also known as ‘Chanakya’ or ‘Vishnugupta’. He wrote a book called ‘Arthashastra’.

The given lesson ‘Ways of Learning’ is an extract from the holy epic ‘Mahabharatha’.

Guru Dronachrya had taught the Pandavas and Kauravas the art of Archery as a part of military service that the princes in those days had to learn.

One day, Guru Dronachrya wanted to test his disciples, so, he asked them to assemble in the large open ground in the front of Hastinapura palace. He asked them to get their bows and arrows and be ready to show off their skills when he called each one of them. They vail agreed enthusiastically. The Guru had set up an artificial bird made of wood and grass on the top of a branch of a tree. The boys were to shoot the bird on the tree.

Guru Dronacharya asked the boys to observe the tree. He then asked one boy to tell him what he saw. The boy told him that he saw the tree, its trunk, branches, the sky over it and the ground below it. He was sent back.

Then he called Yudhishtira, the eldest of Pandavas the and asked him the same question. Yudhistira replied that he could see the tree, the bird, his brothers, friends, and everything. Guru Drona told him that he could not shoot the target. Again, he called the other boys in turns ad asked them the same question. He was not satisfied with their answers.

Later, Drona called Arjuna and asked him if he could see the bird on the top of the tree. Arjuna replied that he could only see the neck and head of the bird. The Guru was pleased and he asked Arjuna to shoot an arrow at the bird.

Arjuna aimed and hit the arrow at the artificial bird’s neck and it fell to the ground.

All the other boys, except the jealous Duryodhana, congratulated Arjuna. Guru Dronacharya blessed Arjuna and advised him that concentration and focus are the keys to success and that he had to be always focused. On another occasion, while Guru Drona was washing his feet in a stream, a crocodile grabbed his foot. He pretended to panic and shouted for the boys to save him. All the other boys who were standing on the bank were awestruck and confused.

And Arjuna bravely responded quickly. He shot an arrow at the crocodile’s mouth skillfully avoiding his guru’s leg and Drona away the crocodile. Thus saving his Guru from the Crocodile. Guru Drona lauded Arjuna for this feat and made an example of Arjuna’s dexterity, prompt and proper responsive action for others to follow. He pointed out that those qualities are the keys to achieve goals and success.

I think that Arjuna was the most favorite disciple of Drona. Arjuna proved that he was a skillful archer. He had the dexterity, promptness and took proper action. He had all the qualities to achieve the goal and success.

No, Drona was not happy with the answers given by many of the princes. Because the Guru expected them to see only the bird and nothing else. He wanted them to learn the quality of concentration and focus, which are the keys to success.

One day, while Guru Dronacharya was washing his feet on the banks of a stream a crocodile grabbed his foot.

Concentration and focus are the key to success.

Guru Drona told him that he could not shoot the target and sent him back. Again he called the other boys in turns and asked them the same question. He was not satisfied with their answers.

Later he called Aijuna and asked him if he could see the bird on the top of the tree. Aijuna replied that he could only see the neck and head of the bird. The Guru was pleased, and he asked Arjuna to shoot an arrow at the bird. Aijuna aimed and hit the artificial bird’s neck and if felt to the ground.

Guru Dronacharya blessed, Arjuna and advised the other boys to concentrate and focus like Arjuna and that those qualities are the key to success.

Once, while Guru Dronaeharya was washing his feet in a stream, a crocodile grabbed his foot. He pretended to panic and shouted for the boys to save him. All the other boys who were standing and the bank were awestruck and confused. But Aijuna bravely responded quickly. He shot an arrow at the crocodile’s mouth, skillfully avoiding his Guru’s leg and drove the crocodile away. Thus Arjuna proved his kill at archery.

Paul Romer and William Nordhaus won Nobel Memorial Prize in Economics for 2018.

Even though being a double amputee, Inglis had to climb at the speed of other able-bodied people. He broke one of his stumps mid-way and he took three times longer to recover after an expedition.

The able-bodied people around Inglis had a very depressing attitude while climbing the mountain. They used to crib about how difficult it was to climb the mountain.

Inglis and his fellow mountaineer had only five cookies between them, the duo survived on half a biscuit a day for the first five days. They spent most of their time praying for relief. On the seventh day of their stay, they received the necessary help. Later, on the thirteenth day, Inglis and his fellow mountaineer were rescued.

The survival story of Mark Inglis is an inspirational story not only for me but also for people who have a habit of complaining at each and every phase of life. The story gives an inspiration to face the difficult situations of life. Even if one is disabled, he should not lose hope and continue, moving towards his goals with a fighting spirit.

Inglis and his fellow mountaineer were stuck in an ice cave forthirteen days. On the seventh day, they got help in the form of a helicopter which dropped food, sleeping bags, a primus and a radio.

I don’t tell them – Main clause

(that) I am disabled – Noun clause

Disability is a state of mind, isn’t it?

The phenomenon of spontaneous emission of radiation by heavy element is called radioactivity.

Example-U, P_o, Th, Ac. etc.

α-rays  β-rays  γ -rays

Commparision of properties of α,β &γ 

Correct answer is (D) Zn²⁺

x-rays and γ-rays do not have the same nature of origin. Production of x-rays and γ-rays are of two type-

(i) Continuous x-rays and

(ii) Characteristics x-rays

The production (origin) of continuous x-rays are explained as follows-When cathode rays are incident on a target and penetrated well inside the atom, then electron from the higher energy orbits jumps to fill in the gaps of the K and M orbits. The difference in the energy of the electrons of both the orbits is manifested in the form of characteristics x-rays. Production of γ-rays- The energy of a stable nucleus is minimum and is then said to be in the ground state. It can be excited by bombarding particles or photons of higher energy. When an excited nucleus to its ground state, γ-rays are produced.

(c) Saturday

The flowers and plants were dropping in a pathetic sort of way. These were dry and faded in the boy’s house.

लड़के के घर के सभी फूल तथा पौधे बहुत ही नीरस व उदास थे तथा वे पूर्ण रूप से मुरझाए हुए थे। और सूख चुके थे।

Saturday was special for the boy because he would pass more time with his mother and less home work to do at home.

शनिवार का दिन लड़के के लिए विशेष था क्योंकि वह अपनी माँ के साथ अधिक समय गुजार सकता था तथा कम गृह कार्य होता था।

(d) The boy’s

Because his mind was so full and happy with the anticipation of his mother and home. In his mind he had also lemon pie and the plants in the garden.

क्योंकि उसका मस्तिष्क माँ की एवं घर की पूर्व स्मृति की खुशी से भरा हुआ था। उसके मस्तिष्क में लेमन पाई और बाग के पौधों के विचार भी थे।

The friends of the boy would spend their Sunday in different ways. Ned was going to see movie. Ram was going for ice-cream with his visiting uncle. Peter was going for horse riding and Gopal was going to attend a wedding.

लड़के के दोस्त रविवार अलग-अलग तरीके से मना रहे थे। नेड फिल्म देखने जा रहा था। राम अपने मिलने आए हुए चाचा के साथ आइसक्रीम खाने जा रहा था। पीटर घुड़सवारी के लिए जा रहा था तथा गोपाल एक शादी समारोह में शामिल होने जा रहा था।

When it was Saturday, the students felt very happy because they were not given homework. The dayscholars had breakfast with boarders. The boys felt pleasure when they heard the clatter of plates and knives, forks, spoons, cups and saucers. They had different types of breakfast on every Saturday. The class started late on this day. Miss Moss gave three coloured action postcards to the best readers. It was a very exciting period for the boys. At last they had English which wound up Saturday morning. On Saturdays, they all went to the library also.

जब शनिवार का दिन आता था तो विद्यार्थी प्रसन्नता अनुभव करते थे क्योंकि उन्हें गृहकार्य नहीं मिलता था। बाहर से आने वाले छात्रों को छात्रावास के छात्रों के साथ नाश्ता करना होता था। लड़के उस समय बहुत प्रसन्न होते थे जब वे प्लेटों, चाकुओं, काँटों, चम्मचों और तश्तरियों की खड़खड़ाहट सुनते थे। उन्हें प्रत्येक शनिवार को भिन्न प्रकार का नाश्ता मिलता था। इस दिन कक्षा भी विलम्ब से आरम्भ होती थी। मिस मॉस, श्रेष्ठ पढ़ने वाले तीन विद्यार्थियों को रंगीन पोस्टकार्ड देती थी। यह कालांश छात्रों के लिये अति रोमांचकारी होता था। सबसे अन्त में अंग्रेजी की कक्षा चलती थी और इसी के साथ शनिवार की सुबह का कार्य पूर्ण हो जाता था। शनिवार को सब अन्त में पुस्तकालय में भी जाते थे।

The correct option is A) Constant.

The susceptibility of paramagnetic substance is Constant.

When a paramagnetic material is kept in a magnetic field it tends to stronger field but when a diamagnetic material is subjected to such a field it tends to move from the stronger to the weaker field.

For experimental test the given liquid (for test) is taken a watch glass. The watch glass (with the small quantity of liquid kept in it) is put on the two pole pieces of a strong electromagnetic which are very close to each other. When a current is passed in the electromagnet circuit, either the liquid (in the watch glass) shows an elevation in the middle or shows a depression in the middle. In the former case the liquids under test is a paramagnetic liquid while in the latter case it is a diamagnetic liquid.

Sulphur in vapour state exists as a diatomic molecule S₂, which contains two unpaired electron in its antibonding molecular orbital. Therefore it is attracted towards magnetic field to show paramagnetism.

Observations from α- particles scattering experiment by Rutherford: 

• Most of the α- particles passed through gold foil undeflected.
• A small fraction of α- particles got deflected through small angles. 
• Very few α- particles did not pass through foil but suffered large deflection nearly 180° they were bounced back to the same medium.

The conclusions drawn by Rutherford from alpha particle scattering
experiment are: -

i. There is a positively charged center in an atom called the nucleus. Nearly all the mass of an atom resides inside the nucleus.

ii. The electrons revolve around the nucleus in well-defined orbits.

iii. The size of the nucleus is very small as compared to the size of an atom.

(iii) Electrons move in a circular path of fixed energy called orbits.

(i) Ernest Rutherford did an experiment to know the structure of the atom inside the atom. 

(ii) He conducted a Gold Foil experiment, in which he attached very thin gold foil with fast moving atoms are known as the alpha(α) particles, with the mass of 4u. 

(iii) These alpha particles are charged Helium ions with mass of 4u. 

(iv) Rutherford concluded the observations from the experiment and gave his interpretation of the inside structure of atom. 

(v) One of the observations made by Rutherford form the experiment was that, the majority of the fast moving α particles passed straight through the layer of foil. 

(vi) The conclusion that Rutherford made from this was, inside the atom, there are lot of empty spaces present because the majority of alpha particles passed through the foil without any deflection from the foil.

Discovery of electrons was done by J.J Thompson. 

Discovery of proton was done by Ernest Rutherford. 

Discovery of neutron was done by James Chadwick.
