Answer:
A. displacement) الازاحة
B. المسافة الفعلية للسيارة distance
You will calculate speed from graph (B) because it's the real distance, but (a) is Unreal distance
(II) speed equal distance / time
Speed =(250*1000/5*60*60).
=13.9888888m/s
From the conservation of mass, matter is not created nor
destroyed. So ponder it this way, for example I put one piece of toast in a

If you put a convinced amount you have to get that quantity back, not less or
not more in broad terms.

What is a wave?
- A wave refers to a transmission of a disturbance from one point to another. It involves transfer of energy from the source to other points.
What are the major types of wave?
- Waves may be classified as longitudinal waves or transverse wave based on the vibration of particles relative to the direction of transmission.
What is a transverse wave?
- A transverse wave is a wave in which the vibration of particles is perpendicular to the direction of transmission of the wave.
- This type of wave contains highest points known as crests and lowest points known as troughs.
