Q: 67 (NDA-I/2022)
Inhabitants are unaware of the speed of rotation of the planet Earth because
1. the angular velocity is constant for each place on the Earth’s surface
2. the atmosphere rotates with the Earth
3. there are no nearby objects, either stationary or moving at a rate different from that of the Earth
Which of the above is/are the correct explanation(s)?

keywords: 

{'angular velocity': [0, 0, 1, 2], 'rotation': [1, 0, 0, 2], 'planet earth': [0, 0, 4, 6], 'earth': [0, 1, 1, 1], 'atmosphere': [1, 1, 4, 7], 'speed': [0, 1, 2, 0]}

The correct explanation is option 4, which states that all three explanations are correct.

Explanation 1 states that the inhabitants are unaware of the speed of rotation of the planet Earth because the angular velocity is constant for each place on the Earth`s surface. This means that the rotation speed of the Earth is the same for everyone, regardless of their location.

Explanation 2 states that the atmosphere rotates with the Earth. This means that the air and gases surrounding the Earth also move in the same direction and at the same speed as the planet`s rotation. As a result, there are no noticeable effects on the atmosphere that would make inhabitants aware of the Earth`s rotation.

Explanation 3 states that there are no nearby objects, either stationary or moving at a rate different from that of the Earth. This means that there are no significant objects or landmarks in close proximity to the inhabitants that would make them perceive any movement or rotation of the Earth.

In conclusion, all three explanations contribute to the inhabitants being unaware of the speed of rotation of the Earth.
