Floating solar panels are generally more efficient than ground-mounted panels mainly because:
तैरते हुए (फ्लोटिंग) सौर पैनल सामान्यतः भूमि पर लगे पैनलों की तुलना में अधिक दक्ष होते हैं, क्योंकि:
Why in News: The Union Cabinet approved a Rs 5,070 crore scheme for 5,000 MW of floating solar capacity along with 10,000 MWh of battery storage on reservoirs across India. Floating solar delivers 5-15% higher efficiency than ground-mounted plants because the water body beneath cools the panels by evaporation – photovoltaic output falls as cell temperature rises. India's technical potential is about 102.18 GWp against roughly 700 MW installed today. Flagship projects: 100 MW Ramagundam (Telangana), 92 MW Kayamkulam (Kerala), 600 MW Omkareshwar (Madhya Pradesh).
Polymorphic malware defeats traditional antivirus software mainly because it:
पॉलीमॉर्फिक मैलवेयर पारंपरिक एंटीवायरस सॉफ़्टवेयर को मुख्यतः इसलिए विफल कर देता है, क्योंकि यह:
Why in News: AI is automating cyber operations, and India was the second most cyber-attacked nation globally in 2024 and sixth in 2025. In polymorphic malware a large language model rewrites the code on every execution, so signature-based antivirus never encounters the same file twice and has no signature to match. Related threats: agentic espionage (an AI agent moves through a multi-stage intrusion without a human operator), and bulk deepfake or hyper-personalised phishing. APT36 has targeted the Ministry of Defence, Army, Navy and DRDO.
In polysilicon manufacturing, the 'Siemens process' refers to:
पॉलीसिलिकॉन निर्माण में 'सीमेंस प्रक्रिया' (Siemens process) किसे संदर्भित करती है?
Why in News: The Ministry of New and Renewable Energy announced a subsidy scheme to build 30 GW of domestic polysilicon capacity by 2030. The Siemens process is the chemical vapour deposition step that deposits ultra-pure polysilicon from trichlorosilane; a fluidised bed reactor is the alternative route. The earlier steps are distinct: electric arc reduction of quartz gives metallurgical-grade silicon (98-99% pure), and fractional distillation removes metals plus boron and phosphorus. Purity grades: solar 6N-9N, semiconductor 9N-11N.
In regenerative agriculture, 'Jeevamrut' is used as a:
पुनर्योजी कृषि (regenerative agriculture) में 'जीवामृत' का उपयोग किस रूप में किया जाता है?
Why in News: Declining soil health and climate variability have brought regenerative agriculture into policy focus. Remember the three farm-derived bio-inputs separately: Jeevamrut is a microbial culture applied to the soil, Beejamrut is used for seed treatment, and Neemastra is the botanical pesticide. Key distinction for Mains: sustainable agriculture tries to prevent further degradation, while regenerative agriculture actively restores ecosystem health. Link it to Zero Budget Natural Farming and the Bharatiya Prakritik Krishi Paddhati.
Exercise Udara Shakti 2026 was held with which country?
अभ्यास 'उदारा शक्ति 2026' (Udara Shakti 2026) किस देश के साथ आयोजित किया गया?
Why in News: The Indian Air Force concluded Exercise Udara Shakti 2026, a biennial bilateral air combat exercise with the Royal Malaysian Air Force, held in Malaysia. Learn the neighbouring pairs to avoid confusion: Garuda is with France, Pitch Black with Australia, and Samudra Shakti with Indonesia. Malaysia operates the Su-30MKM, a close cousin of India's Su-30MKI, which lets the two air forces share deep maintenance and technical expertise on the same platform family.
The National Skill Development Corporation (NSDC) functions under which Union ministry?
राष्ट्रीय कौशल विकास निगम (NSDC) किस केंद्रीय मंत्रालय के अधीन कार्य करता है?
Why in News: NSDC, with Cultus Education and support from Amazon Web Services, launched a nationwide online cloud and AI skilling programme. NSDC is the nodal agency under the Ministry of Skill Development and Entrepreneurship, with AWS as technology partner – a public-private partnership model. Two-tier design: 150,000 learners in a self-paced foundational layer, and 10,000 qualified participants in the free cohort-based AWS re/Start track, targeted at Tier-2 and Tier-3 towns.
INS Mangrol uses waterjet propulsion mainly in order to:
आईएनएस मंगरोल (INS Mangrol) में वॉटरजेट प्रणोदन का उपयोग मुख्यतः किस उद्देश्य से किया गया है?
Why in News: The Indian Navy received INS Mangrol, the third indigenously built Mahe-class Anti-Submarine Warfare Shallow Water Craft, from Cochin Shipyard Limited. Three marine diesel engines drive high-efficiency waterjets instead of conventional propellers: this gives sharp manoeuvrability in shallow draft and, critically, lower underwater acoustic noise – essential when hunting midget submarines in littoral waters. Note: indigenous content is over 80%, speed up to 25 knots, and Mangrol is a port town in Junagadh district, Gujarat.
In the designation H5N1, the letters 'H' and 'N' stand for:
H5N1 नामकरण में 'H' तथा 'N' अक्षर किसके द्योतक हैं?
Why in News: Australia confirmed its first mainland case of Highly Pathogenic Avian Influenza H5N1 in a mammal – a long-nosed fur seal at Beachport, South Australia. H and N are the two surface glycoproteins, Haemagglutinin and Neuraminidase, that name influenza A subtypes. H5N1 was first isolated in 1996 in Guangdong, China (Gs/Gd lineage), with the first human outbreak in Hong Kong in 1997; the present panzootic is driven by clade 2.3.4.4b. Each spillover into a mammal is another chance for mammal-adapting mutations.
The world's oldest known terrestrial material, zircon crystals dated to about 4.4 billion years, has been found in:
विश्व की ज्ञात सबसे प्राचीन स्थलीय सामग्री – लगभग 4.4 अरब वर्ष पुराने ज़िरकॉन क्रिस्टल – कहाँ से प्राप्त हुई है?
Why in News: Australia is in focus after the H5N1 mammalian case, making its physical geography exam-relevant. The ancient Precambrian Western Shield of Australia holds zircon crystals dated to roughly 4.4 billion years – the oldest known terrestrial material. Also remember: Australia is the world's smallest continent and sixth-largest country, capital Canberra, lying between the Pacific and Indian Oceans, with the Great Dividing Range along the east and the Great Barrier Reef off the north-east coast.
Consider the following statements regarding Exercise Udara Shakti 2026:
1. It is a biennial bilateral exercise conducted with the Royal Malaysian Air Force.
2. It is built around Dissimilar Air Combat Training (DACT), in which pilots fly against aircraft types different from their own.
3. India participated with Su-30MKI fighters, while Malaysia fielded Rafale jets.
Which of the statements given above is/are correct?
अभ्यास 'उदारा शक्ति 2026' के संबंध में निम्नलिखित कथनों पर विचार कीजिए:
1. यह रॉयल मलेशियन वायु सेना के साथ आयोजित एक द्विवार्षिक (biennial) द्विपक्षीय अभ्यास है।
2. यह डिससिमिलर एयर कॉम्बैट ट्रेनिंग (DACT) पर केंद्रित है, जिसमें पायलट अपने से भिन्न प्रकार के विमानों के विरुद्ध उड़ान भरते हैं।
3. भारत ने इसमें Su-30MKI लड़ाकू विमानों के साथ भाग लिया, जबकि मलेशिया ने राफेल विमान उतारे।
उपर्युक्त कथनों में से कौन-सा/से सही है/हैं?
Statement 1 (correct): Udara Shakti is a biennial bilateral tactical air combat exercise with the Royal Malaysian Air Force, held in Malaysia. Statement 2 (correct): It is built around Dissimilar Air Combat Training, where crews fly against unfamiliar aircraft types – exposing them to different radar signatures, turn rates and tactics rather than mirror-image opponents. Statement 3 (incorrect): The aircraft are reversed – India deployed Rafale fighters with C-17 Globemaster III airlift, while Malaysia fielded Su-30MKM Flankers, F/A-18D Hornets and the A400M Atlas. The deployment followed Exercise Pitch Black, demonstrating extended operational reach.
