Its range 350 KM which is less than Agni and Brahmos (450km) missile jointly developed by India and Russia. While Prithvi, Dhanush and Agni are ballistic missiles Brahmos is a cruise missile.
Consider the following statements:
$$1$$. A Lagrangian Point is a point in the space where the gravitational pull of the $$2$$ celestial bodies balance each other.
$$2$$. Aditya would be placed at Lagrangian Point L-$$3$$ and James Webb Space Telescope would be placed at the Lagrangian Point L-$$2$$

Explanation
A Lagrange point is a location in space where the combined gravitational forces of two large bodies. India’s first solar mission, Aditya would be placed in Halo Orbit around the Lagrangian Point L1. It would study Corona and Chromosphere of the Sun.
Consider the following statements about 'Quantum Computing'.
$$1$$. Qubits is the smallest unit of Quantum Computing.
$$2$$. A Qubit can have only $$2$$ values, either $$1$$ or $$-1$$.

Explanation
In a normal computer, information is
stored as bits (either zero or one). Instead of this, a quantum computer has quantum bits. Q
uantum computers work on Qubits.
Qubits work faster because of the way such circuits are designed. A
Qubit or quantum bits may be 0, 1 or any value between them
superimposed to appear 0 or 1.
Consider the following statements about 'INS KALVARI'.
$$1$$. It is a Scorpene Class submarine developed indigenously by India.

Explanation
INS Kalvari is an Indian submarine that has recently been commissioned into the Indian Navy. It was built at Mazagaon Docks Limited, Mumbai with the assistance of French Naval Company DCNS. It is the first out of the 6 Scorpene-class submarines that India plans to acquire. This submarine has been named after the dreaded tiger shark, a deadly deep sea predator of the Indian Ocean.
Consider the following statements about 'Supercritical Carbon Di Oxide Brayton Test Loop Facility'.
$$1$$. It uses supercritical carbon dioxide as the working fluid which is half as dense as the normal steam.
$$2$$. The thermal inputs to the Brayton Test Facility can be the conventional sources and the non-conventional as well including the solar and the nuclear sources of energy.

Explanation
Brayton Test Loop Facility is a technology that uses Supercritical Carbon Di Oxide for generation of power. Indian scientists at IISC, Bengaluru, have indigenously developed the Super Critical Carbon Di Oxide Brayton Test Loop facility. Supercritical Carbon Di Oxide would replace steam as the working fluid in power plants. Brayton test loop facility can be linked to solar thermal sources of heat thus, enhancing the amount of green & renewable energy.
