'Matching concept ' is one of the fundamental assumptions and has a significance in accounting. It entails that expenses should be matched with the income of that accounting period in order to obtain/ascertain the financial result of that period.....So for this purpose..we will match expenses with revenue of that period...

Given Revenue= 21000
Expenses = 15000

Income will be = revenue - expenses= 21000 - 15000 = 6000

Answrs:

1. नीत्शे एक प्रसिद्ध दार्शनिक थे। वे एक ऐसा देवता तलाश कर रहे थे, जो मनुष्य की पहुँच में हो और उसी की तरह नाच-गा सके और जो मनुष्य की तरह ही जीवनयापन करे।
2. "ईश्वर मर गया है" नीत्शे ने यह इसलिए कहा होगा क्योंकि उसे ऐसा देवता नहीं मिला जो जीवन से भरपूर हो। जो मनुष्य की तरह हँसे-रोए, काम करे और कराए।
3. कृष्ण के व्यक्तित्व में विरोधाभास लगता है क्योंकि वे नाचते गाते हैं, काम करते हैं। एक ओर वे योगी हैं, तो दूसरी ओर कर्मयोगी भी हैं।
4. 'कर्मण्येवाधिकारस्ते' ........ का आशय है कि काम करो बाकी सब भूल जाओ। यहाँ तक कि काम के फल की इच्छा भी मत करो।मनुष्य का अपना काम है बिना किसी फल की इच्छा के कर्म करते रहना।

Lewis dot structures reflect the electronic structures of the elements, including how the electrons are paired. Lewis structures are a useful way to summarize certain information about bonding and may be thought of as “electron bookkeeping”. In Lewis dot structures each dot represents an electron. A pair of dots between chemical symbols for atoms represents a bond.

Lewis Structure of CO (Carbon Monoxide)

• A carbon monoxide molecule consists of one carbon atom and one oxygen atom.
• The carbon atom requires four electrons to obtain octet configuration whereas the oxygen atom requires two.
• Therefore, the valency is satisfied via the donation of a lone pair of electrons for bonding by the oxygen atom.
• The resulting Lewis electron dot structure displays a triple bond connecting a carbon and an oxygen atom, each holding a lone pair of electrons.

The going concern concept

• It is one of the most fundamental concepts
• It forms the assumption on which all accounting operations are carried out
• According to this concept all accounting transactions must be recorded and reported  with the assumption that the business will continue to operate for the foreseeable future
• It is assumed that the business will keep Fixed Assets and Current Assets as well as
• Liabilities
• it is assumed that the entity will realize its assets and settle its obligations in the normal course of the business
• If this changes assets should be recorded at their Net realizable value instead of at cost

The consistency concept

• Due to the nature that a number of transactions can be treated in a number of alternative ways
• It is possible to constantly create a favorable set of financial statements simply by changing the way these items are created
• For example depreciation can be accounted for using either the straight line and reducing balance method
• A business may be tempted hop from method to method depending on which method enhances it’s profit for example
• The consistency concept prevents this from happening
• It dictates that once the business adopts an accounting principle or method, it must continue to follow it consistently in future accounting periods
• Any change in accounting policies/principles must be disclosed
• This ensures consistent accounting records are comparable from period to period

Under Section 58 of the Indian partnership Act, 1932, a firm may be registered at any time (not merely at the time of its formation but subsequently also ) by filing an application with the Registrar of Firms of the area in which any place of business of the firm is situated or proposed to be situated. The Registration of a partnership firm is not compulsory under Part vii of the Indian Partnership Act, 1932, though it is usually done as registration brings many advantages to the firm. It is optional for partners to set the firm registered and there are no penalties for non-registration.

According to Bohr,

• When energy is supplied to atoms of hydrogen, the electron from lower energy gets excited to higher energy level.
• The excited state being unstable, it jumps back to its original state that is ground state.
• Some electrons move to their ground state in one jump, some in multiple jumps. Each jump corresponds to line in a spectrum.
• As we know the gas in tube consists of many hydrogen atoms.
• Therefore, each electron on getting energy gets excited.
• On returning to the ground state, they either move in single jump or multiple jump.
• This is the reason that we get so many lines in different regions in hydrogen spectrum.

The wavelength emitted by them can be calculated as:

The laburnum tree looks yellow and still in September afternoon sunshine. It bursts into activity and life when the goldfinch arrives. There is plenty of sound and movement in its branches.

Or

detailed answer

At the start of the poem, the top of the Laburnum tree in the poem is silent and still. There is hardly any activity on it as the sunlight falls on it on a September afternoon. However, with the arrival of the goldfinch, it suddenly becomes a place of feverish activity. The silence of the place is broken by the twittering and chirruping of the chicks and the goldfinch.

I think that the change brought about by the arrival of the goldfinch on the Laburnum top is good, as it breaks the monotony. The tree becomes alive and lively with the movement of the goldfinch and the twitterings and chirrupings of the chicks.

Change can be good or bad in life depending on a situation. However, the fact is that change is the only constant in life. So, even if a change is bad, we have to accept it and move on in life.

Hence proved

The internal (thylakoid) membrane vesicles are organized into stacks, which reside in a matrix known as the stroma. All the chlorophyll in the chloroplast is contained in the membranes of the thylakoid vesicles. The stacks of thylakoid sacs are connected by stroma lamellae. The lamellae act like the skeleton of the chloroplast, keeping all of the sacs a safe distance from each other and maximizing the efficiency of the organelle.

How does the author point out the importance of Green Movement?

Answer:

The author points out the importance of the Green Movement by comparing it to the revolutionary ideas of Copernicus. He had taught mankind in the 16th century that the earth and the other planets revolved round the sun.
