Multiple choice

ஒரு இரயில் மணிக்கு 90 கி.மீ வேகத்தில் சென்று ஒருமின் கம்பத்தை 12 வினாடிகளில் கடக்கிறது எனில, இரயிலின் நீளம் என்ன? If a train goes at 90 km / h and crosses a battery in 12 seconds, what is the length of the train?

  1. 400 மீ/ 400 m

  2. 300 மீ/300 m

  3. 500 மீ/ 500m

  4. 450 மீ/450 m

  5. இவற்றில் ஏதுமில்லை/None of these

B Correct answer
Explanation

Speed = 90 km/h = 90 * (5/18) m/s = 25 m/s. Length = Speed * Time = 25 * 12 = 300 meters.

AI explanation

The speed of the train is 90 km/h, which we convert to meters per second by multiplying by 5/18, giving 25 m/s. A battery is considered a stationary point, so the distance covered is just the length of the train. Using the formula distance = speed * time, we calculate the length as 25 * 12 = 300 meters. The length of the train is 300 m.
