Question

Представьте себя сидящим в купе поезда с занавешенным окном. Звукоизоляция столь хороша что перестук колес во время движения услышать невозможно. Сможете ли вы определить движется ли поезд с постоянной скоростью, или же он стоит неподвижно?

Answer 1

Я думаю, не получится определить, если положить шар на пол. на подъёме поезда, шар не останется неподвижным

Answer 2

Identifying Train Movement

Hello there! If I were sitting in a train compartment with a closed window and excellent sound insulation, it would be quite challenging to determine whether the train is moving at a constant speed or is stationary. However, there are a few subtle cues that could help in making this determination.

Firstly, if I were to observe the movement of objects outside the window, such as trees, buildings, or other landmarks, I could potentially gauge the train's speed based on how quickly these objects pass by. Additionally, if there are any vibrations or swaying motions felt within the train, it could indicate that the train is in motion.

However, without access to these visual and physical cues, it would be difficult to definitively determine the train's movement solely based on the lack of sound from the wheels.

Based on the provided information, it seems that the sound insulation is so effective that the sound of the wheels during movement cannot be heard. This suggests that the train could be either stationary or moving at a constant speed, as the absence of wheel noise does not provide conclusive evidence of the train's status.

In conclusion, while it would be challenging to determine the train's movement solely based on the lack of wheel noise, other visual and physical cues would be necessary to make a more accurate determination.
