Consider the following statements: [2023]
1. Ballistic missiles are jet-propelled at subsonic speeds throughout their flights, while cruise missiles are rocket-powered only in the initial phase of flight.
2. Agni-V is a medium-range supersonic cruise missile, while BrahMos is a solid-fuelled intercontinental ballistic missile.

The description in the pair refers to stars and not to giant clouds of dust and gas. Hence, this pair is incorrect. Nebulae: Nebulae are giant clouds of dusRead more
Let’s evaluate the pairs one by one:
Therefore, only one of the pairs is correctly matched.
The answer is: Only one.

Hydrofluorocarbons (HFCs) are synthetic chemicals widely employed in industries, mainly for refrigeration and cooling purposes. These man-made compounds were introduced as alternatives to ozone-depleting substances that are being phased out under the Montreal Protocol. HFCs are specifically designed for applications in refrigeration, air-conditioning, aerosol propellants, and insulating foams, with additional, smaller roles in fire protection and as solvents. Unlike some other compounds, HFCs lack lubricating properties. Therefore, the correct option is Only three.

Let's evaluate the two statements: Statement 1: Ballistic missiles are typically rocket-propelled and follow a parabolic trajectory that reaches the upper atmosphere before re-entering and hitting the target at high speeds, often supersonic or hypersonic. Cruise missiles, on the other hand, are typiRead more
Let’s evaluate the two statements:
Statement 1:
The statement that ballistic missiles are jet-propelled at subsonic speeds throughout their flight and cruise missiles are rocket-powered only in the initial phase is incorrect. In fact, it should be the other way around: Ballistic missiles are rocket-propelled throughout their flight, while cruise missiles are jet-powered for most of their flight.
Statement 2:
Therefore, Statement 2 is also incorrect.
Conclusion:
Both statements are incorrect.
The correct answer is: Neither 1 nor 2.
