2. D. A billboard on the side of the road. Because let's be honest, trying to observe the speed of a car while looking at an airplane or a car next to you is like trying to eat soup with a fork - it's just not gonna work! Stick to the billboard, my friend.
3. B. Meter. It's the perfect SI unit for distance because it's like your trusty measuring tape. Just make sure you don't accidentally use it to measure your self-worth, because that's immeasurable.
4. D. A person sitting next to you. They'll just be sitting there, motionless, like a statue. It's like having your very own human mannequin. Now that's what I call stylish travel companionship!
2. The correct answer is D. A billboard on the side of the road.
To observe the speed of a car that you are traveling in, you need a reference point that is not moving relative to the car. In this case, the billboard on the side of the road is stationary and does not move relative to the car. By observing the distance between the moving car and the stationary billboard over time, you can calculate the speed of the car.
3. The correct answer is B. Meter.
The International System of Units (SI) is the modern metric system used globally for scientific and everyday measurements. The SI unit for distance is the meter (m). It is used to measure length, height, width, and any other type of linear measurement.
4. The correct answer is D. A person sitting next to you.
When you are riding on a train, the person sitting next to you would appear to not be moving, even though the train is in motion. This is because the person is moving at the same speed and direction as you, therefore their motion is relative to yours. On the other hand, the conductor walking by you, the building you are passing, and a flying bird would all appear to be moving as they are moving relative to the train.
