Science & Technology MCQs

A qubit (quantum bit) is the basic unit of quantum information. Unlike a classical bit which can only be 0 or 1, a qubit can exist in a superposition of both 0 and 1 simultaneously, allowing for exponentially more complex computations.

Quantum computers leverage quantum mechanical phenomena such as superposition (where a qubit can be 0, 1, or both simultaneously) and entanglement (where qubits become linked and share the same fate) to perform computations in ways classical computers cannot.

NISAR is designed to use two different radar frequencies: L-band (provided by NASA) and S-band (provided by ISRO). These dual-frequency capabilities allow it to penetrate vegetation and ice, providing comprehensive data on Earth's surface changes.

The primary objective of the NISAR mission is to observe and measure changes in Earth's land and ice surfaces, including ecosystem disturbances, ice-sheet collapse, and natural hazards like earthquakes and volcanic eruptions, with unprecedented detail.

NISAR stands for NASA-ISRO Synthetic Aperture Radar. It is a joint mission between the U.S. space agency NASA and the Indian Space Research Organisation (ISRO) to measure changes in Earth's surface.

MIRV technology allows a single ballistic missile to carry multiple warheads, each capable of being directed to a different target. This significantly enhances the missile's strike capability and ability to overcome missile defense systems.

The Defence Research and Development Organisation (DRDO) is the premier agency of the Government of India, charged with the military's research and development, and is responsible for the development of various missile systems, including the Agni series.

Agni-VI is a proposed Intercontinental Ballistic Missile (ICBM) under development by India. Its estimated maximum range, as per design specifications, is between 8,000 and 12,000 kilometers, making it capable of reaching targets across continents.
