Answer:
Surface waves are the kind of waves that occur on the surface of the ocean. The reason behind their occurrence is the geological effects, usually in the form of winds in near geographical regions or in that region.
These waves reach the land when the geological winds give a push to the waves and they travel miles and finally hit the land. These waves range in sizes, for small sizes to the the size of tsunami.
7). The displacement is how far away from the starting point the object ends up being. Since the person is running a lap, they should end up at the same place they started.
The distance is given in the problem, so:
a). 600
b). 0
8). To find the distance, calculate the perimeter. Since the book ends up at the original location, the displacement is zero, so
a). 0
b). 14
Using the same strategy:
9a. 150 - 75 = 75
9b. 150 + 75 = 225
9c. 150 + 75 = 225 both times
10a. 14 + 7 + 2 = 23
10b. 14 - 7 + 2 = 9
11a. 10 + 4 + 2 = 16
11b. 10 - 4 + 2 = 8
