Consider the following statements: Hypersonic speeds are 5 or more tim...
The correct answer is option 'A' which means statement 1 only is correct.
Explanation:
1. Hypersonic speeds are 5 or more times the speed of sound.
This statement is correct. Hypersonic speeds refer to speeds that are 5 or more times the speed of sound. The speed of sound is approximately 343 meters per second or 1,235 kilometers per hour. Therefore, any speed that is 5 times or more than this would be considered hypersonic. Hypersonic speeds are typically achieved by advanced aerospace vehicles or missiles that use scramjet or ramjet engines.
2. The BrahMos is a medium-range ramjet hypersonic cruise missile.
This statement is incorrect. The BrahMos missile is not a hypersonic cruise missile. The BrahMos is a supersonic cruise missile developed jointly by India and Russia. It is named after the Brahmaputra and Moskva rivers. The missile operates at supersonic speeds, which means it travels faster than the speed of sound but not at hypersonic speeds. The BrahMos missile is known for its high speed, precision, and versatility.
In conclusion, statement 1 is correct as hypersonic speeds are indeed 5 or more times the speed of sound. However, statement 2 is incorrect as the BrahMos missile is not a hypersonic cruise missile but a supersonic cruise missile.
