​Noise pollution:

Noise pollution is generally defined as regular exposure to elevated sound levels that may lead to adverse effects in humans or other living organisms. According to the World Health Organization, sound levels less than 70 dB are not damaging to living organisms. Exposure for more than 8 hours to constant noise beyond 85 dB may be hazardous.

Sources of Noise Pollution:

• Industrial pollution
• Agricultural machine pollution
• Household pollution
• Transport pollution
• Defense equipment pollution 
• Miscellaneous Sources:

Impacts of noise pollution on a human being:

• Physiological effect: Any effect on the natural process of the body like pain in the heart and narrowing of arteries.
• Psychological effect: Affects the thinking, feeling, Emotions overall mental health of a person.
• Physical effect: Affects the external structure of a person.

Key Points

Thus, Montreal Protocol is related to ozone depletion.

Mostly composed of methane, the Compressed Natural Gas (CNG) is the cleanest of all the fossil fuels. It is called the cleanest fuel because when burnt, it produces only carbon dioxide and water vapor. Its key points are:

• It is used as an alternative to petrol and diesels because it is cheaper, greener and more efficient.
• It is compressed to increase the storage capacity of vehicles.
• It is environmentally friendly.
• It is safer than petrol and diesel.

Hence, the full form of CNG is Compressed Natural Gas.

Use of Alum:

• Alum, also known as aluminium sulfate (Al₂(SO₄)₃.18H₂O) is added to water in order to help in the sedimentation of suspended impurities.
• Alum is a universal coagulant.
• It destabilizes the mud particles suspended in it through the process known as coagulation. 
• Alum when added to water attaches to the suspended particles and increases their size forming a floc.
• This floc is due to an increase in size and weight settling at the bottom of the container.
• These are removed by pouring out the clean water layer formed at the top.

Thus, Rekha's mother adds Phitkari (Alum) to water collected from the pond every day in order to sediment light-suspended impurities.

Additional Information 

• Hard water is water that contains a high amount of dissolved minerals (calcium and magnesium salts in the form of bicarbonates, chlorides, and sulfates.)
• Hard water does not lather with soap.
• Soft water is surface water that contains low dissolved minerals.
• Alum does not kill germs, in general, bleaching powder is used to kill germs in the water.
• Alum does not decolourize water.

Concept-

The World Health Organization (WHO) has categorized biomedical waste into eight categories. They are:

• Infectious Waste – Any biomedical waste that is infectious or contaminated.
• Sharps – Sharps objects like needles, scalpels, broken glass, and razors.
• Pathological Waste – Body parts of humans or animals, including tissues, fluids, or blood.
• Pharmaceutical Waste – Unused drugs, medicine, or creams that are expiring.
• Genotoxic Waste – Toxic drugs and hazardous toxic waste
• Radioactive Waste – Any waste containing potentially radioactive materials
• Chemical Waste – Liquid waste from machines, batteries, and disinfectants is chemical.
• General/Other Waste – All other non-hazardous waste.

Former Pakistan Prime Minister and Pakistan Peoples Party (PPP) leader Yusuf Raza Gilani has been elected Chairman of the Senate, the upper house of Parliament. PML-N's Syedul Khan Nasir was elected unopposed as Deputy Chairman of the Senate. In a session of the Pakistani Senate, a total of 41 newly elected senators took oath as members of the House.

The Indian government aims to set up 'Bharat Park,' a trade zone in the UAE, with showrooms and warehouses to display and store Indian-made goods, facilitating international transactions and showcasing products globally.

Mamta G Sagar, a Kannada poet, won the World Literary Prize for her significant contributions to literature, as recognized by the World Organization of Writers during the first Congress of WOW in Nigeria. This award highlights her achievements in winning international literature prizes.

Reliance Industries (RIL) has announced a merger deal with Viacom18 Media and The Walt Disney Company to establish a joint venture (JV) integrating Viacom18 and Star India operations. With RIL committing a significant investment of Rs 11,500 crore (approximately US$ 1.4 billion) into the JV, this strategic move aims to reshape the Indian entertainment and sports industry landscape.

The US House of Representatives has bolstered the Quadrilateral Security Dialogue (Quad) by passing legislation to strengthen ties among the member nations – USA, Australia, India, and Japan. The bill mandates the creation of an Intra-Parliamentary Working Group for regular discussions among lawmakers, fostering political exchanges. It also instructs the Biden Administration to submit a report for enhanced governmental coordination within 180 days, urging talks with partner countries within 60 days to establish a parliamentary group.

Autotrophs are organisms that can produce their own food using light energy through photosynthesis or by using chemical energy through the process of chemosynthesis.

Hence, autotrophs obtain carbon from inorganic sources like carbon dioxide.

Heterotrophs cannot synthesize their own food and are dependent on other organisms for nutrition.

Hence, heterotrophs obtain reduced carbon in the form of carbohydrates from other organisms.

A geologist is a person who studies the earth. Geologists study the structure of the Earth, and they have found that it is made up of four main parts. The earth has a solid inner core, a liquid outer core, a mantle, and a crust.hence, option (D) is correct.

Velocity acquired by the two bodies falling from rest through a distance his given as v = 

Given that :

Average speed= (Total Distance)/(Total time)

= (20 m + 40 m)/(5 sec + 5 sec)

=60 m/10 sec

=6m/s

The ratio of time for the travel is 4:3 (Sinhagad to Deccan Queen). Hence, the ratio of speeds would be 3:4.
Since, the sum of their average speeds is 70 kmph, their respective speeds would be 30 and 40 kmph respectively.
Use alligation to get the answer as 34.28 kmph.

This is a complex trial and error based question and the way you would have to think in this is:

From the figure above, it is clear that A is faster as he takes only t + 2 hours while B has taken t +
9 hours to complete the journey.
Then, we get: (t – 6)/9 = 8/t
Solving for t, we get t = –6 (not possible)
Or t = 12. Putting this value of t in the figure it changes to:

We also get ratio of speeds = 3 : 2 (inverse of ratio of times)
The next part of the puzzle is to think of the 12 km less traveled by the first person till the meeting
point.
If the speed of the faster person is 3s, that of the slower person = 2s.
Further
12 × 2s – 6 × 3s = 12 km
s = 2 kmph.
The speed of the faster tourist is 3 × 2 = 6 kmph

Since the two horses meet after 200 minutes, they cover 0.5% of the distance per minute
(combined) or 30% per hour. This condition is satisfied only if you the slower rider takes 10
hours (thereby covering 10% per hour) and the faster rider takes 5 hours (thereby covering 20%
per hour).

Hence, Option A is correct.

He introduced the tradition of beginning the cholaepigraphs with historical introductions. He streamlined the administrative system with the division of the country into various districts and by standardizing revenue collection through systematic land surveys.Being an ardent devotee of Lord Shiva, he built the magnificent Peruvudaiyar Temple (also known as the Brihadeeswarar Temple) in Thanjavur and through it enabled wealth distribution amongst his subjects. His successes enabled his son Rajendra Chola I to extend the empire even further.
 

A is the correct option. Muhammad Tughlaq

Narendra Modi did become Prime Minister on May 26, 2014, and his government did focus on the "Sabka Saath, Sabka Vikas" development plan.

To an observer on Earth the stars appear to twinkle. This is due to the fluctuation of physical conditions in the earth’s atmosphere.  Each single stream of starlight is refracted and is caused to change direction. This is because the light which passes the different layers of atmosphere differ in temperature and density. This causes the light from the star to twinkle when seen from the ground.

A pH value of 7 indicates that the solution is neutral. The pH scale is a measure of the concentration of H⁺ ions in a solution. A pH of 7 signifies a neutral solution, where the concentration of H⁺ ions is balanced.

It is because boiling point is a particular temp. at which a liquid starts changing into gas at the atmospheric pressure.
