Regular Reflection: When light falls on a smooth uniform surface (like a mirror), all the parallel incident rays are reflected perfectly parallel. This is called Regular Reflection.

• Haveli is the traditional houses made to live which is multi-storeyed building where a very large family used to live in.
• And bungalow is a single storeyed building build in a small space with a open ground where a nuclear family lives in.
• Haveli is very large but bungalow is not very large.

High initial price: LEDs are currently more expensive (price per lumen) on an initial capital cost basis, than most conventional lighting technologies.

Temperature dependence: LED performance largely depends on the ambient temperature of the operating environment – or "thermal management" properties. Over-driving an LED in high ambient temperatures may result in overheating the LED package, eventually leading to device failure. An adequate heat sink is needed to maintain long life. This is especially important in automotive, medical, and military uses where devices must operate over a wide range of temperatures, which require low failure rates. Toshiba has produced LEDs with an operating temperature range of -40 to 100 °C, which suits the LEDs for both indoor and outdoor use in applications such as lamps, ceiling lighting, street lights, and floodlights.

Voltage sensitivity: LEDs must be supplied with the voltage above the threshold and a current below the rating. Current and lifetime change greatly with a small change in applied voltage. They thus require a current-regulated supply (usually just a series resistor for indicator LEDs).

Light quality: Most cool-white LEDs have spectra that differ significantly from a black body radiator like the sun or an incandescent light. The spike at 460 nm and dip at 500 nm can cause the color of objects to be perceived differently under cool-white LED illumination than sunlight or incandescent sources, due to metamerism, red surfaces being rendered particularly badly by typical phosphor-based cool-white LEDs. However, the color-rendering properties of common fluorescent lamps are often inferior to what is now available in state-of-art white LEDs.

LIBERALS...

Liberals are the groups who wanted to change the society that tolerated all the religions. Liberals opposed the uncontrolled power of monarchy. They did not believe in Universal Adult Franchise too..

RADICALS...

Radicals are those who wanted a nation which was based on majority of country's population. They supporated women's Suffragette movements. They opposed the privilege of landowners and nobles....

CONSERVATIVES...

They are those who opposed both liberals and radicals

Rate of flow of water = 60 litres/minute

Volume of the tank = 108 m³

1 m³ = 1000 litres

108 m³= 108000 litres

Time taken to fill the complete tank = 108000/60 = 1800 minutes = 1800/60 hours = 30 hours

The tank will be filled completely in 30 hours.

• A public prosecutor represents the state in any criminal case. It is because a crime is considered a crime against the entire society.
• After the completion of the enquiry by the police, the public prosecutor begins the prosecution on behalf of the state.
• A public prosecutor has to act impartially while examining facts and witnesses. He/she then has to present his/her arguments based on the evidences before the court.

Pollutants that deplete the ozone layer are chlorofluorocarbons (CFC), nitrogen oxides and hydrocarbons. CFC is used in air conditioners and refrigeration, as cleaning solvents, aerosol propellants, in foam insulation and in certain fire extinquishers. These pollutants react with ozone molecules and disintegrate them.

Let the man salary be before increment= x
There is 10% increase in the salary= x+ (10/100)x 
                                                         = x + 0.1 x
                                                          = 1.1x
Increased salary = 154000
Therefore 1.1 x = 154000 x
                        = 154000/1.1= 1,40,000
Hence the original salary was 1,40,000

Let the original salary be ₹100
Therefore new salary i•e 10% increase = 100+10=₹110
New salary is ₹110 when original salary =₹100
New salary is ₹1 when original salary =100/110
New salary is 154000 when original salary =100/110×154000=140000
original salary is 140000

The point where energy is released is called the focus or hypocentre. It is generally located at the depth of 60 km.

Let the time taken by second car overtake to the first car be x hours after it started.

 Total time taken by first car = (x + 1) hours.

 Total distance covered by first car in (x + 1) hours = 60(x + 1) km .

 Distance covered by second car in x hours = 80x .

Thus, Distance covered by first car is equal to second car .

∴ 60(x + 1) = 80x .

⇒ 60x + 60 = 80x .

⇒ 60 = 80x - 60x .

⇒ 60 = 20x .

{tex}⇒ \bf{\dfrac{60}{20}} = x{/tex}

∴ x = 3 .

Hence, the second car travelled in 3 hours to overtake the 1st car .

Therefore, time taken by second car to overtake the first car = 80x = 80 × 3 = 240 km.

The moderates were the early Congress men who led the Indian National Congress from 1885 to 1905.

They were aware of the might of the British rule in India and wanted to protect the youth of India from the batons and guns of British.

They resorted to peaceful means and moderate methods of appeasement like petitioning, publishing pamphlets, taking out processions etc.

They published newspapers, wrote articles, and showed how British rule was leading to the economic ruin of the country.

They criticised British rule in their speeches and sent representatives to different parts of the country to mobilise public opinion.

Following are the  functions of the Parliament:

• The members of the Lok Sabha select the executive wing of the Government. The Executive implements the laws which are made by the Parliament.
• The leader of the ruling party which gets the majority in the Lok Sabha elections is chosen as the Prime Minister of the country. He selects the Council of Ministers and the cabinet ministers who look after various departments such as defence, health and education.
• The Rajya Sabha is the Upper House of the Parliament. It represents various states of India in the Parliament as its members are elected by the elected members of the Legislative Assemblies of the states.
• The Parliament can control and review the work of the Government. The session of the Parliament begins with a ‘Question Hour’, where the members of the Parliament question various policies of the Government. They thus control the executive by asking questions on the implementation of various policies.
• The opposition parties play an important role by questioning various policies of the Government. It draws the attention of the people towards the flaws in government policies.
