You are seated in a train that is stopped at a station Use two different reference points to explain that the train can appear to be moving and not moving?

When looking out the window, if you focus on a distant building outside the train, it may appear that the train is not moving because the building is not changing position relative to the train. However, if you look at a nearby platform or another train beside yours, you may notice the train's movement compared to these closer reference points, making it appear that the train is indeed moving.


You are standing on a scale in an elevator Suddenly you notice your weight decreases What do you conclude?

Explain how a moving car can become positively active?

A moving car can become positively charged through processes like friction, which can cause the transfer of electrons between the car and another object. For example, when the car drives on the road, friction between the tires and the ground can result in the car gaining a positive charge if electrons are transferred from the road to the car.


Will a listener notice the Doppler effect if he or she and the source of the sound are traveling toward each other?

Yes, the listener will notice the Doppler effect in this scenario. As they are moving towards each other, the sound waves will be compressed, leading to a higher frequency and shorter wavelength, resulting in a higher pitch to the listener.

Mark some of the stars in its place on the polythene by looking through it. After a few days do the same and you would notice the difference in their relative positions.
