Answer:
1. 5 m/s
2. 8 m/s
3. 10 s
4. 3 m/s
Explanation:
1. Average speed = distance / time
s = 20 m / 4 s
s = 5 m/s
2. First, find the time to travel from A to B:
60 m = 10 m/s × t
t = 6 s
Now find the average speed from A to C:
s = 80 m / (6 s + 4 s)
s = 8 m/s
3. If t is the time traveling from C back to B, and the average speed of the whole trip is 5 m/s, then:
5 m/s = 100 m / (6 s + 4 s + t)
t = 10 s
4. Average velocity = displacement / time
v = 60 m / 20 s
v = 3 m/s

Answer:
what is the question please?
Answer: The Bluray Disk can store more information
The wavelenght of red light is around 700nm, whereas the wavelenght of violet light is around 400nm. Since the violet light has smaller wavelenght the data tracks on a Blu-ray Disk can be spaced closer together and the Blueray Disk can store more information
Explanation: Because a disk work by storing data using bits, the more bits can be stored in one place improves the total storage on the unit. The less the space to storage the bit, the more space overall for the disk.
Answer: As air rises the moisture in it slowly reaches its saturation point and when this happens, tiny crystals of water start to condense and form clouds.
