Answer:
no way to tell since the ocean surface is moving too violently it's not possible to determine the reflected angle

When the temperature of a substance is increased, the kinetic energy of the particles of the substance is increased as well.
This can lead to thermal expansion such as an increase in length of the substance or increase in volume of the substance.
This can also lead to change of state of the substance, for example change of state from solid to liquid or from liquid to vapor.

Explanation:
Answer:
a. When the total displacement is -(A + B)
b. A + B = 1 m or -(A + B) = -11 m
c. 0 m
Explanation:
a. Under what circumstances can you end up back at your starting point?
If we have the displacement A and displacement B. The total displacement is A + B. We would end up at the starting point if we take a displacement -(A + B) from point B
b. What is the magnitude of the largest displacement you can end up from the starting point?
The maximum displacement we can obtain is when A and B are in the same direction. So A + B = 5 m + 6 m = 11 m or -A - B = -(A + B) = -11 m.
c. When A and B are perpendicular, what is the component of B in the direction of A?
Since A is perpendicular to B, the angle between A and B is 90°
So the component of B in A,s direction is Bcos90° = B × 0 = 0 m
