Frankly I don't think this is a very good question. Too many ifs in the answers.
1. I don't agree with a flying bird as an answer; however, it the bird were flying at the same speed (reference the ground) as the train and in the same direction, that could be the right answer. The correct answer is a person sitting next to you. That person is moving at the same speed as you are and going in the same direction.
2. "Observe the speed of a car that you are traveling in?" How accurate is that to be made? I don't think any of them will do if you want to know the speed of the vehicle in which you are traveling. See how fast the billboard on the side of the road whizzes by is an indication of how fast you are traveling but won't come close to telling you how fast. I would think a car next to you traveling at the same speed and in the same direction would do it IF both drivers had a walkie talkie radio and could communicate with each other.
Thank you everyone who thinks these questions are arbitrary and can't be answered decisively one way or another.
To determine which of the following would look as if it's not moving while you are riding on a train, you need to consider the concept of relative motion. When you are on a moving train, objects outside the train may appear to be moving or not moving, depending on their relative motion compared to the train.
In this case, the conductor walking by you and the person sitting next to you are both on the train, so they will appear to be moving with you. The building you are passing will appear to be moving in the opposite direction as the train. However, a flying bird will not be connected to the train and can move independently, so it will appear to be stationary or not moving relative to the train.
Now, to determine which reference point would allow you to observe the speed of a car that you are traveling in, you need to consider what reference point would provide a comparison to the car's motion. To observe the car's speed, you would need a reference point outside the car.
An airplane flying across the sky might not be a reliable reference point since it could be moving at a different speed and direction relative to the car. A car traveling next to you at the same speed you are traveling would be a good reference point because it is moving at the same speed as your car. However, a car traveling next to you at a faster speed than you are traveling would not be an accurate reference since it is moving faster than your car.
Therefore, the most appropriate reference point to observe the speed of the car you are traveling in would be a billboard on the side of the road. Since the billboard is stationary and not connected to the car, you can compare the speed of the car relative to the stationary billboard to determine its speed.
****** ***** ************** is correct I got 100% on my quick queck
