Science & Technology MCQs

The fundamental unit of information in a quantum computer is the qubit (quantum bit). Unlike classical bits that can only be 0 or 1, qubits can exist in a superposition of both 0 and 1 simultaneously.

Quantum computing has the potential to revolutionize various fields, including drug discovery and materials science (developing new antibiotics), complex simulations for weather forecasting, and optimization problems in financial modeling.

Maintaining qubit coherence, which is the ability of qubits to remain in a superposition of states, is a significant challenge in building stable and functional quantum computers. Qubits are highly sensitive to environmental noise.

The Geosynchronous Satellite Launch Vehicle Mark III (GSLV Mk III), now renamed LVM3, is the launch vehicle being adapted for the Gaganyaan mission to carry the crew module.

The initial human spaceflight mission of Gaganyaan is planned to be of approximately 3 days duration, orbiting the Earth.

The primary objectives of the Gaganyaan mission are to demonstrate human spaceflight capability, conduct microgravity experiments, and enhance scientific knowledge and technological development. Establishing a permanent lunar base is not an objective of this mission.

INSAT-4DS is designed to improve the capacity and reach of satellite-based communication services, thereby enhancing India's digital communication infrastructure and connectivity, especially in remote areas.

The INSAT-4DS satellite was launched by ISRO's heavy-lift launch vehicle, GSLV-F14, from the Satish Dhawan Space Centre in Sriharikota.

INSAT-4DS is a communication satellite designed to augment the existing communication services provided by ISRO's INSAT constellation, primarily for broadcasting and telecommunication applications.

Communicating with deep-space missions involves overcoming significant challenges including signal loss over vast distances, the inherent time delay (latency) due to the speed of light, and the requirement for advanced communication technology.
