A. 1 only
B. 2 only
C. Both 1 and 2
D. None of the above
Solution & Detailed Explanation
Answer: (A) 1 only
Detailed Explanation
- The Afro-Asian conference held in the Indonesian city of Bandung in 1955, commonly known as the Bandung Conference, marked the zenith of India’s engagement with the newly independent Asian and African nations.
- The Bandung Conference later led to the establishment of the NAM. The First Summit of the NAM was held in Belgrade in September 1961.
Question 4
Science and Technology | Space | Medium | The Hindu
SOURCE
Consider the following:
1. The PUNCH Mission will place four satellites in the Medium Earth Orbit.
2. PUNCH is a NASA Small Explorer mission that will make global, 3D observations of the young solar wind, from the outermost solar atmosphere to the inner heliosphere.
Which of the statements above is or are correct?
A. 1 only
B. 2 only
C. Both 1 and 2
D. None of the above
Solution & Detailed Explanation
Answer: (B) 2 only
Detailed Explanation
- It will be a constellation of four, suitcase-sized satellites each weighing about 64 kg sent to the Low Earth Orbit (LEO).
- It will have three Wide Field Imagers (WFI) and one Narrow Field Imager onboard. Once every four minutes, each of the four cameras will capture three raw images using different polarising filters.
- In addition, each camera will capture an unpolarised image once every eight minutes
- It is the first time that a solar mission has been specifically designed to make use of the polarisation of light to measure the corona and solar wind, that too, in 3D.
- It will provide scientists with new information which could lead to more accurate predictions about the arrival of space weather events on Earth and impact on humanity’s robotic explorers in space.
- It will measure polarised light using polarising filters, enabling scientists to look into the inner solar system.
- PUNCH’s four-camera setup will operate as a single, virtual instrument to generate large-scale imagery data, making it a unique information-loaded 3D image of the solar corona.
Question 5
Science And Technology | WHO | Easy |The Hindu
SOURCE
Consider the following:
1. Dextrose
2. Trisodium citrate dihydrate
3. Sodium chloride
4. Total osmolarity of 311mOsm/L.
Which of the above is incorrect with respect to WHO recommended ORS?
A. 1 only
B. 2 and 3 only
C. 4 only
D. None of the above
Solution & Detailed Explanation
Answer: (C) 4 only
Detailed Explanation
- The World Health Organization (WHO) approves a low-osmolarity ORS formula that contains glucose, sodium chloride, potassium chloride, and sodium citrate. This formula is specifically designed for effective rehydration by restoring fluids and electrolytes lost during dehydration.
- Composition of the WHO-approved ORS formula :
- Dextrose (glucose): 13. 5 grams per liter. Glucose is a primary ingredient that facilitates the absorption of sodium and water.
- Sodium chloride: 2. 6 grams per liter.
- Potassium chloride: 1. 5 grams per liter.
- Trisodium citrate dihydrate: 2. 9 grams per liter.
- Total osmolarity: 245 mOsm/L.
