Belgium, a small European country, has Dutch-, French- and German-speaking populations. While 59% of the total population of the country live in the Flemish region and speak Dutch, the other 40% of the people live in the Wallonia region and speak French. In Brussels, the capital of Belgium, about 80% of the people speak French, while the remaining 20% speak Dutch.

The Path of accommodation adopted in Belgium by following ways:-

        1) Dutch and French speaking ministers shall be equal in the central govt.

        2) Many Powers of the central government have been given to state govt. The state govt are not subordinate to the central govt.

        3) Brussels has a separate govt in which both the communities have equal representation. 

        4) There is a third kind of govt called community govt elected by the people belonging to Dutch, French and German no matter where they live

 (i) Draw BC = 7 cm.

(ii) Construct ∠YBC = 75°.

(iii) From ray BY, cut-off line segment BD = AB + BC = 13cm.

(iv) Join CD.

(v) Draw the perpendicular bisector of CD meeting BY at A.

(vi) Join AC to obtain the required triangle ABC.

 Justification

Since A lies on the perpendicular bisector of CD.

∴  AC = AD 

Now   BD = 13 cm

⇒  BA + AD = 13 cm

⇒  BA + BC = 13cm

Hence, △ABC is the required triangle.

2z +5z= 6z

(5 + 2)z = 6z

7z - 6z = 0

(7-6)z =0

z = 0

Answer:
After they celebrated Christmas, the weather changed for the worse. On the early morning of 2 January, the waves became huge. As the ship rose to the top of each wave, they could see the vast sea rolling towards them. The wind seemed to be howling.

Answer:
They dropped the storm jib and lashed a heavy mooring rope in a loop across the stem to slow the boat, and then double-lashed everything, went through their life-raft drill, attached lifelines, put on oilskins and life jackets

What were the difficulties that they faced that night?
Answer:
The night was bitterly cold, and they were pumping water out of the ship, steering the ship and working the radio. Moreover, they were getting no replies to their calls for help, as they were in a remote comer of the world.

Answer:
Sue had bumped her head and there was a big bump above her eyes. She had two black eyes, and a deep cut on her arm. She showed remarkable maturity for a seven-year-old when she said that she didn’t want to worry them when her father was trying to save all of them

The narrator and his wife had always dreamt of sailing. They wanted to do a round-the-world voyage like Captain James Cook had done 200 years earlier. For sixteen years they spent all their leisure time improving their seafaring skills in the British waters. They took a boat, Wavewalker, that was 23 metres, and weighed 30 ton. It had been professionally built and they spent months fitting it out and testing it in the roughest weather that they could find. Finally, in July 1976, the family set out to sail from Plymouth, England.

Public baths were a striking feature of Roman urban life (when one Iranian ruler tried to introduce then into Iran, he encountered the wrath of the clergy there! Water was a sacred element and to use it for public bathing may have seemed a desecration to them), and urban populations also enjoyed a much higher level of entertainment.

For example, one calendar tells us that spectacular (shows) filled no less than 176 days of the year!

When they reached the southern Indian Ocean, one of the world’s roughest seas, they began to encounter strong winds. Apart from the gales, the size of the waves was alarming. It was as high as the main mast. Things became worse on 2 January when the waves became huge. The ship rose to the top of each wave and they could see endless waves approaching them, and the screaming of the wind seemed horrifying to them. To slow the boat down, they dropped the storm jib and lashed a heavy mooring rope in a loop across the stem. Then they double-lashed everything, went through their life-raft drill, attached lifelines, donned oilskins and life jackets.

Question 
What was the first indicator of rough weather?
Answer:
On their second day out of Cape Town, they encountered strong winds. For the next few weeks, the gales blew continuously. The gales did not worry the narrator but the sizes of the waves were disturbing.

Answer:
The four of them the narrator, his wife Mary, son Jonathan, and daughter Suzanne sailed for 105,000 kilometres to the west coast of Africa to Cape Town. They took on two crewmen with them an American, Larry Vigil, and a Swiss, Herb Seigler, before settling sail on the southern Indian Ocean.

Answer:
The narrator was a thirty-seven-year-old businessman, who along with his family, set from Plymouth, England, on a round-the-world voyage like Captain James Cook had done 200 years earlier in a 30-ton wooden-hulled boat.

As we know Germenium Ge has the ground state electron configuration of 1s², 2s², 2p⁶, 3s², 3p⁶, 4s², 3d¹⁰, 4p²

Now in the condition of GeX₂ the two electrons are removed from the p shell,

and in case of GeX₄ the more two electrons are removed from 4s shell because it has low energy than d shell and the rest configuration remains same .

Now according to the question GeX₄ is more stable because it does not have a full valence so it is unfilled valance so GeX₄ is more stable than GeX₂.

On the other hand,

in pbx2 , oxidation state of pb =+2  

and pbx4 , oxidation state of pb =+4  

we know ,

oxidation state of +2 is more stable than +4 . due to inert pair effect.

RBCs are the biconcave cells and without nucleus in humans; also known as erythrocytes. RBCs contain the iron-rich protein called haemoglobin;  give blood its red colour. RBCs are the most copious blood cell produced in bone marrows. Their main function is to transport oxygen from and to various tissues and organs.

Leucocytes are the colourless blood cells. They are colourless because it is devoid of haemoglobin. They are further classified as granulocytes and agranulocytes. WBCs mainly contribute to immunity and defence mechanism.

Following are the important functions of the nuclear membrane:

• The nuclear envelope has tiny holes which are identified as nuclear pores. The pores enable the content to flow in and out of the nucleus. It also connects the outer membrane and the inner membrane.

• The nuclear envelope’s surface area extends and doubles the nuclear pores during the interphase part of cell division.

• Nuclear membrane shields the nucleus with a double membrane by many pores that help in controlling the crossing of macromolecules such as proteins and RNA and permit free passage of water, ions, ATP and small molecules. The membrane controls the flow of information in the cell as it is conducted by the macromolecules.

p = 4 , q = - 3 , r = 2

Value of p³ + q³ - r³ - 3pqr

= 4³ + ( -3 )³ - 2³ - 3 × 4 × ( - 3 ) × 2

= 64 - 27 - 8 + 72

= 136 - 35

= 101
