Daily Current Affairs MCQ: 31st July 2024 - Question 3

Consider the following statements:

1. Higher temperatures at high altitudes cause air to be less dense, leading to reduced lift for aircraft.

2. Aircraft wings generate lift due to the faster airspeed over the top surface compared to the bottom surface, as explained by Bernoulli's principle.

3. Higher temperatures increase the density of air, which in turn enhances the engine performance of aircraft.

Which of the statements given above is/are correct?

Detailed Solution for Daily Current Affairs MCQ: 31st July 2024 - Question 3

1. Higher temperatures at high altitudes cause air to be less dense, leading to reduced lift for aircraft: This statement is correct. Higher temperatures cause the air to expand, reducing its density. As a result, there are fewer air molecules beneath the aircraft's wings, which reduces the lift generated.

2. Aircraft wings generate lift due to the faster airspeed over the top surface compared to the bottom surface, as explained by Bernoulli's principle: This statement is also correct. Bernoulli's principle states that within a horizontal flow of fluid, points of higher fluid speed will have less pressure than points of slower fluid speed. This principle explains why the air pressure above the wing is lower than below, creating lift.

3. Higher temperatures increase the density of air, which in turn enhances the engine performance of aircraft: This statement is incorrect. Higher temperatures actually decrease the density of air, which adversely affects engine performance by reducing the amount of oxygen available for combustion, thereby decreasing thrust.

Therefore, the correct answer is Option B: 1 and 2 Only.

Daily Current Affairs MCQ: 31st July 2024 - Question 4

What impact does higher temperature at high altitudes have on aircraft operations, particularly in places like Leh?

Detailed Solution for Daily Current Affairs MCQ: 31st July 2024 - Question 4

Higher temperatures at high altitudes, such as in Leh, lead to a decrease in air density, resulting in fewer air molecules beneath an aircraft's wings to generate sufficient lift. Additionally, the thinner air affects engine performance by reducing the oxygen available for combustion, thereby decreasing thrust. This necessitates longer runways and more powerful engines for takeoff due to reduced thrust, making it more challenging for aircraft to operate effectively under such conditions.

Daily Current Affairs MCQ: 31st July 2024 - Question 5

Consider the following statements:

Statement-I:
The Geological Survey of India (GSI) discovered lithium inferred resources of 5.9 million tonnes in Jammu and Kashmir's Reasi district, marking a significant milestone.

Statement-II:
The GSI identified another reserve of lithium in Degana, Rajasthan's Nagaur district, larger than the one in Jammu and Kashmir, potentially meeting 80% of India's lithium demand.

Which one of the following is correct in respect of the above statements?

Detailed Solution for Daily Current Affairs MCQ: 31st July 2024 - Question 5


Statement-I is correct as it highlights the GSI's discovery of lithium inferred resources in Jammu and Kashmir. Statement-II is also correct as it mentions the discovery of another lithium reserve in Degana, Rajasthan, which is anticipated to be larger than the one in Jammu and Kashmir and capable of fulfilling a significant portion of India's lithium demand. Therefore, both statements are accurate, with Statement-II providing additional information that supports and complements Statement-I.

Daily Current Affairs MCQ: 31st July 2024 - Question 6

What is the primary purpose of the National Pharmaceutical Pricing Authority (NPPA) in India?

Detailed Solution for Daily Current Affairs MCQ: 31st July 2024 - Question 6

The National Pharmaceutical Pricing Authority (NPPA) in India primarily focuses on ensuring affordable access to medicines by regulating the pricing of pharmaceutical products. This regulatory body plays a crucial role in monitoring and enforcing drug prices, fixing and revising prices of scheduled drugs, and ensuring compliance with pricing regulations to make essential medications accessible to the general population.

Daily Current Affairs MCQ: 31st July 2024 - Question 7

Consider the following pairs regarding the reasons behind Leh flight cancellations:

1. Bernoulli's principle - Faster-moving air results in lower pressure above the wings.

2. Thinning of air - Higher temperatures cause air to expand and become denser, resulting in more air molecules beneath an aircraft's wings.

3. Impact on engine performance - Thinner air reduces the oxygen available for combustion, decreasing thrust.

4. Landing challenges - Thinner air affects braking and reverse thrust functionality, making landings more challenging.

How many pairs given above are correctly matched?

Detailed Solution for Daily Current Affairs MCQ: 31st July 2024 - Question 7

1. Bernoulli's principle - Correct. Bernoulli's principle states that faster-moving air results in lower pressure above the wings compared to the pressure below. This difference in pressure creates lift for the aircraft.

2. Thinning of air - Incorrect. Higher temperatures cause air to expand and become less dense, resulting in fewer air molecules beneath an aircraft's wings, not more. This reduces the lift generated by the wings.

3. Impact on engine performance - Correct. Thinner air reduces the oxygen available for combustion, which decreases the thrust produced by the engines. This makes it harder for planes to take off in hotter conditions.

4. Landing challenges - Correct. Thinner air affects braking and reverse thrust functionality, making landings more challenging. In thin air, the reverse thrust generated might not be adequate for safe landing.

Thus, pairs 1, 3, and 4 are correctly matched.

2. Hezbollah was founded in 1982 to combat Israeli forces in Lebanon and has significantly enhanced its military capabilities since the 2006 war.

3. The conflict between Israel and Hezbollah is partly due to Hezbollah's support for Palestinians facing Israeli bombardment in Gaza.

Which of the statements given above is/are correct?

Detailed Solution for Daily Current Affairs MCQ: 31st July 2024 - Question 8

- Statement 1: This statement is incorrect. While Israel captured the Golan Heights during the Six-Day War in 1967 and effectively annexed the territory in 1981, this annexation is not recognized by the international community.

- Statement 2: This statement is correct. Hezbollah was indeed founded in 1982 to combat Israeli forces in Lebanon, and it has significantly enhanced its military capabilities since the 2006 war, possessing a large arsenal of rockets and advanced weaponry.

- Statement 3: This statement is correct. The conflict between Israel and Hezbollah is partly due to Hezbollah's support for Palestinians, particularly in the context of Israeli bombardments in Gaza.

Therefore, the correct answer is Option D.
