Science & Technology MCQs

The NGLV is envisioned as a cost-effective, three-stage, reusable heavy-lift launch vehicle designed to replace operational launch vehicles like the PSLV and GSLV.

Semi-cryogenic engines typically use Liquid Oxygen (LOX) as oxidizer and refined kerosene (RP-1) as fuel, offering higher thrust and being more cost-effective than fully cryogenic engines.

Quantum computing is expected to revolutionize drug discovery, material science, and complex optimization problems due to its ability to process vast datasets simultaneously.

The National Quantum Mission aims to develop intermediate-scale quantum computers with 50-1000 physical qubits over a period of 8 years.

C-DAC (Centre for Development of Advanced Computing) under the Ministry of Electronics and IT developed QSim to enable researchers to write and debug quantum algorithms.

The GSAT-N series is designed to provide high-throughput satellite (HTS) capacity to support India's Digital India initiative, focusing on broadband and inflight/maritime connectivity.

Due to the high mass of the GSAT-N2 (approx 4700 kg), ISRO utilized the SpaceX Falcon 9 launch vehicle for its deployment in 2024-25.

ISRO has transitioned to the GSAT-N series (specifically GSAT-N2/GSAT-20) to provide high-throughput satellite (HTS) capacity to meet the growing demand for broadband and inflight connectivity.

The primary scientific goal of LIGO-India, along with the US LIGO observatories, is to detect gravitational waves. These ripples in spacetime are generated by cataclysmic cosmic events like the merger of black holes and neutron stars, providing a new way to observe the universe.

The LIGO-India observatory is being established in the Hingoli district of Maharashtra. This location was chosen for its seismic stability and low population density.
