15 March : Daily Current Affairs Quiz

Answer: Option B - Officially recognized languages of India

Explanation:

• The Eighth Schedule of the Indian Constitution lists officially recognized languages, ensuring their promotion and development.
• Originally containing 14 languages, it now includes 22.
• Inclusion in the schedule allows languages to be used in government communications, parliamentary proceedings, and competitive exams.
• However, it does not grant classical language status or financial benefits automatically, nor is it related to caste recognition or state formation.

Answer: Option A - It provides continuous solar observation without Earth’s shadow

Explanation:

• The Lagrange Point 1 (L1), located about 1.5 million km from Earth, offers an uninterrupted view of the Sun, free from Earth's shadow.
• This allows Aditya-L1 to continuously monitor solar activity, including solar flares and coronal mass ejections, improving space weather predictions.
• Unlike other orbits, L1 ensures real-time observation of the Sun’s outer layers without periodic obstructions.

Answer: Option A - By disrupting satellite communications and power grids through geomagnetic storms

Explanation:

• Intense solar flares release high-energy radiation and charged particles, which can cause geomagnetic storms when they interact with Earth's magnetosphere.
• These storms can disrupt satellite operations, interfere with radio communications, induce voltage fluctuations in power grids, and even cause large-scale blackouts.
• Other options are incorrect, as solar flares do not significantly alter Earth's surface temperature, trigger volcanic eruptions, or accelerate Earth's orbital decay.

Answer: Option D - Single-axis and dual-axis tracking systems

Explanation:

• Single-axis and dual-axis tracking systems enhance solar panel efficiency by adjusting their orientation to follow the sun's movement, maximizing sunlight absorption.
• Single-axis trackers tilt panels along one direction (east-west or north-south), while dual-axis trackers adjust both tilt and rotation for optimal exposure.
• This increases energy output compared to fixed panels.
• These systems are widely used in large solar farms to improve performance and maximize electricity generation.

Answer: Option B - To promote domestic rooftop solar adoption for free electricity in households

Explanation:

• The PM Surya Ghar: Muft Bijli Yojana aims to promote rooftop solar adoption in residential households by providing subsidies and collateral-free loans.
• It ensures free electricity, reduces carbon emissions, and enhances energy self-reliance.
• The scheme supports India's renewable energy goals by targeting 1 crore households by 2026-27.
• By integrating financial incentives and a streamlined digital application process, it accelerates the transition to clean energy across urban and rural areas.
