Radial component of linear momentum does not contribute to angular momentum.

Initial speed of the three-wheeler, u = 36 km/h

Final speed of the three-wheeler, v = 10 m/s

Time, t = 4 s

Mass of the three-wheeler, m = 400 kg

Mass of the driver, m' = 65 kg

Total mass of the system, M = 400 + 65 = 465 kg

Using the first law of motion, the acceleration (a) of the three-wheeler can be calculated as: v = u + at

a = (v - u)/t = (0 - 10)/4 = -2.5 m/s² 

The negative sign indicates that the velocity of the three-wheeler is decreasing with time.

Using Newton’s second law of motion, the net force acting on the three-wheeler can be calculated as:

F = Ma

= 465 × (–2.5) = –1162.5 N

The negative sign indicates that the force is acting against the direction of motion of the three-wheeler

\(\oint \overrightarrow{{B}} \cdot \overrightarrow{{d} l}=\mu_{0}\left(I_{c n}\right)\)

Here u = 36 kmh^-1 = 36 x 5/18 = 10 ms^-1

v = 0; t = 4s

and total mass = 400 + 65 = 465 kg

As v = u + at, ⇒ 10 + 4a = 0

⇒ a = -2.5 ms^-2

Retarding force = 465 x 2.5 = 1162.5 N

(d) No limit

(b) Joint venture account

• Need of Registration : No need of registration in joint venture while registration is very necessary in partnership.
• Name: There is no name of joint venture, but there is a specific name of partnership.

Memorandum joint venture account nature is just like a Trading and Profit & Loss A/ c.

Like, joint consignment of goods, joint construction of a building, bridge, hotel, joint underwriting of a particular issue of share and debentures import, export, purchase of land & building, purchase & sale of constructed building, flat, etc.

(b) Co-venturer

In Joint venture, minimum number of ventures are two and no limit of maximum number of members.

Profit and loss of joint venture is distributed in agreed ratio if there is not shown agreed ratio in question the P & L distributed equally.

Supplier’s account is credited on credit purchase in joint venture.

• Joint Venture with A/ c
• Memorandum Joint Venture A/c

When co-venture are living at the same place and venture business is so big, separate books in joint venture keeping is appropriate.

These three accounts are opened.​​​​​​:

1. Joint Venture Account
2. Joint Bank Account
3. Co-venture’s Capital/Personal Account

Compulsory dissolution can happen in following circumstances :

• When firm’s business becomes Illegal.
• When any partners should resident of enemy country.
• When all or except one partner are declared insolvent.
• If no, of partners are excess in general partnership 50 or in banking business 20.
• When court orders dissolution of a firm.

Test to distinguish dil H₂SO₄ from dil HCl and HNO_3- BaCl₂ soln. when added to dil. H₂SO₄ gives a white ppt. of BaSO₄ , but with dil. HCl and dil. HNO₃ , no white ppt. is produced – since BaCl₂ and Ba(NO₃)₂ are soluble in dil. H₂SO₄ .

Barium chloride can be used to distinguish between sulphuric acid and nitric acid. Out of these two acids only sulphuric acid gives a white precipitate with barium chloride solution. 

1. 2NaOH + H₂SO₄ (dil) → Na₂SO₄ + 2H₂O 

2. Pb(NO₃ )₂ + H₂SO₄ (dil) → PbSO₄ + 2HNO₃

(1) Zinc (or any other reactive metal) reacts with dil. H₂SO₄ to give hydrogen. 

Zn (s) + H₂SO₄ (aq.) → ZnSO₄ (aq.) + H₂ (g) 

(2) Sodium carbonate reacts with dil. H₂SO₄ to give CO₂

Na₂CO₃ (s) + H₂SO₄ (aq.) → Na₂SO₄ (aq.) + H₂O(l) + CO₂ (g) 

The above reaction can also be carried out with NaHCO₃ (sodium bicarbonate) or KHCO₃ (potassium bicarbonate)

1. Preparation of Hydrogen chloride gas. 

B: Non-volatile acid 

2. Preparation of Copper sulphate from copper oxide. 

A: Typical acid property 

3. Action of cone. Sulphuric acid on Sulphur. 

C: Oxidizing agent

Action of concentrated sulphuric acid on carbon. 

C + 2H₂SO → CO₂ + 2H₂O + 2SO₂

Concentrated sulphuric acid has a great affinity for water and as such it is a hygroscopic liquid. Being Hygroscopic, it absorbs moisture from the atmosphere and hence cone, sulphuric acid is kept in air tight bottles.

(a) Commissioned by the Mughal place where different process of production of books like making paper, printing, painting, pinding etc. were done. 

(b) They are important source for studying the empire and its court.

(i) Chronicles commissioned by the Mughal emperors are an important source for studying the empire and its court. They were written in order to project a vision of an enlightened kingdom to all those who came under its umbrella. The authors of Mughal chronicles focused on events-related to life of the ruler, their family, the court and nobles, wars and administrative system. 

(ii)These chronicles were written in Persian. This language flourished as a language of the court and of literary writings, alongside north Indian languages, especially Hindavi and its regional variants. As the Mughals were Chaghtai Turks by origin, Turkish was their mother tongue. 

(iii)Chronicles narrating the events of a Mughal emperor’s reign contained, alongside the written text, images that described an event in visual form. 

(iv)When scenes or themes in a book were to be given visual expression, the scribe left blank spaces on nearby pages; paintings, executed separately by artists, were inserted to accompany what was; described in words.

As per the instructions from the Mughal Emperors, the palace historians kept a diary of the important happenings in the country. These are the Chronicles. They talk about the achievements of the Mughal rulers. They also give chronologically important events. Chronicles are an important source to study about the Mughal Capital and Mughal Empire.

Chronicles give a chronological account of incidents.

The Mughal chronicles are great sources to know about Mughal history.

• They give information regarding the founding of the Mughal Empire.
• They tell us about the policies and schemes the Mughal Kings wanted to implement.
• They tell us how theories of all kinds developed and how they reached the people.

• One of the aims was to let people know the policies of the state.
• Another aim. was to let the enemies of the country know that their efforts were bound to fail and they would be defeated.
• A third aim was to leave the records of the Mughal rule to future generations.

When Akbar asked Abul Fazl to write the history of his rule, he also asked his aunt Gulbadan to help. He asked her the record the memoirs of Babar and Humayun. Akbar thought that this would help Abul Fazl in his work. Gulbadan Began accepted this challenge and wrote a book titled ‘Humyunnama’. It was the description of Humayun and his rule. It looks into the private life of the Mughals. It is not a book of praise singing. She has written here about the fights and confrontations among the kings and princes. She has also shown how the elderly ladies of the family helped in solving such disputes.

Kandahar was an important military and commercial city. This was a fort-city and there were conflicting claims about this between the Mughals and the Safavids of Iran. Initially, Kandahar was under Humayun. Two years after the death of Humayun Iran took possession of that city. In 1595 Akbar recaptured it. Although the Safavids had diplomatic ‘ relations with the Mughals, they continued to claim Kandahar. In 1613, Shah Jahan sent a diplomatic representative to the Court of Shah Abbas in Iran. The idea was to let the Mughals continue to have power over Kandahar. But the mission failed. In 1622, the Persian Army attacked Kandahar. The Mughal army was not battle-ready to defend the place. They were forced to give up Kandahar to Safavids. All efforts to recapture it later failed.

(1) Small subunit of ribosome encounters mRNA and protein synthesis process begins. 2 sites in the large subunit for subsequent amino acids to bind to and thus be close enough to each other for the formation of the peptide bond. 

(2) The order and sequence of the amino acid are defined by the bases in m-RNA. 

(3) In the first phase the amino acid are activated in the presence of ATP and linked to t-RNA- (aminoacylation of t-RNA) 

(4) Ribozyme/Ribosome acts as a catalyst for formation of peptide bond. 

(5) A translational unit has a sequence of RNA that is flanked by start codon (AUG) at 5' end and stop codon at 3'end (UAA, UAG, UGA). 

(6) Initiation-ribosome binds to m-RNA at start codon (recognized by tRNA). 

(7) Elongation phase: Amino acids linked to tRNA bind to appropriate codon of mRNA by complementary base pairing. 

(8) Ribosome moves codon to codon along mRNA- polypeptide sequence formed as dictated by DNA & represented by mRNA. 

(9) At the end termination occurs by a release factor which binds to stop codon releasing the polypeptide. 

Ribosome is the cellular factory.

Correct answer is (a) Real Account

Procedure for preparation of Receipts and payments account as follows.

1. This account always starts with opening balance of cash in hand and cash at bank, cash in hand always has a debit balance and hence appears on the debit side as the first item. Cash at bank has either a debit balance or a credit balance (overdraft). 

2. All receipts made in cash during the accounting year will be shown on the debit side and all cash payments made during the accounting year are shown on the credit side.

3. Only actual cash receipts and cash payments are recorded in this account. 

4. At end of the accounting period, this account is balanced and it shows the closing balance of cash in hand and at bank or bank overdraft, as the case may be.

Correct answer is b) Nominal a/c.

While preparing an Income and Expenditure account, the following points are to be considered. 

1. This account is prepared usually in “T” form taking revenue expenses on the debit side and the revenue incomes on the credit side. 

2. It is also prepared in vertical form. Under this method, the total of revenue incomes are shown first, revenue expenses follow it. After this, the total of expenses is deducted from the total of the incomes for ascertaining the surplus or deficit.

3. It is prepared to nd out the current year’s surplus or deficit, it does not have any opening balance. Therefore, previous year’s surplus or deficit is not important. 

4. This account takes only the revenue incomes and revenue expenses. Capital receipts and payments are not taken into account. 

5. Since it is maintained under accrual basis, current year’s income and expenditures alone are shown. 

6. Outstanding expenses, accrued incomes, prepaid expenses, income received in advance, depreciation, provision, etc. in the current year are to be suitably adjusted. 

7. At the end of the accounting year the income and expenditure account is balanced and it reffects either a surplus or a deficit which is transferred to capital fund.

When total internal reflection occurs from a prism, the entire incident light (100%) is reflected back into the denser medium. Whereas in ordinary reflection from a plane mirror, some light is refracted and absorbed so the reflection is partial.
