Answer: Diagnostic
Explanation: For sure!
There's not enough information in the question to calculate the player's velocity. But we can find his average speed.
Speed = (distance covered) / (time to cover the distance)
Speed = (15 meters) / (3 sec)
Speed = (15/3) (m/s)
Speed = 5 m/s
There's no information telling us what direction he ran, so it's not possible to say anything about his velocity. ('Velocity' is not just a big word for 'speed'. It's a different thing, and to describe it, you need to know the speed AND the direction of the motion.)
B. Matter moves at right angles to the direction of a longitudinal wave, and at right angles to the direction of a transverse wave.
C. A longitudinal wave does not need matter through which to travel, while a transverse wave does.
D. A longitudinal wave needs matter through which to travel, while a transverse wave does not.
Answer:
B
Explanation:
Transverse waves cause the medium to move perpendicular to the direction of the wave. Longitudinal waves cause the medium to move parallel to the direction of the wave.
