Answer:
In electromagnetic waves.
Explanation:
Energy is transferred through vibrations of electric and magnetic fields. In sound waves, energy is transferred through vibration of air particles or particles of a solid through which the sound travels. In water waves, energy is transferred through the vibration of the water particles.
Answer:
1. True
2. True
3. False
4. False
5. True
6. False
Explanation:
Acceleration: It refers to the change in velocity/speed of an object with respect to time. When the speed increases with time we call it acceleration and when its decreases it is called as deceleration. Let us analyze each instance individually:
1. When roller coaster starts to roll down the track its speed will increase with time. That means it is accelerating.
2. When the ball reaches at the peak of its trajectory, it comes to a stop for a fraction of a second that means it decelerates.
3. Since the velocity remains constant there is no acceleration.
4. Since the speed is no changing with time, there is no acceleration.
5. Since the moving plane comes to a stop, it is a case of deceleration.
6. Since the truck is moving at a constant speed so the acceleration is zero.
