Out of the following given choices;
A) It is always difficult to get a project like this approved. This study will help them convince the local community to support the project.
B) If they do not perform the study, and there is a problem during the dredging project, the media could make them look bad.
C)The study will weigh the benefits against the negative impacts so an informed decision can be made.
D)The study will demonstrate the local government's concern for the community's safety.
The answer is; C
Dredging can have a negative impact on the marine environment. Destruction of this ecosystem could have reverberating effects that affect the communities that rely on this ecosystem for livelihoods, such as fishermen. An environmental and feasibility study will help weigh the benefits and demerits of the project and allow for an informed decision to be made.
Answer:
Average speed = 2.22m/s
Velocity = 0.89 m/s west
Explanation:
(i) Since speed is a scalar quantity, the direction of movement by the person is irrelevant. Therefore,
Average speed = total distance traveled / time taken
Where;
Total distance = 70m + 30m = 100m
Time taken = 45 seconds
Average speed = 100 / 45 = 2.22m/s
(ii) However, velocity is a vector quantity and so the direction of movement by the person is of utmost importance. Therefore,
Velocity = displacement / time taken
Where;
displacement = -70m + 30m [<em>West direction is taken as negative and east is taken as positive</em>]
displacement = -40m [<em>The negative sign just means that the net displacement is in the direction of the West</em>].
Thus, displacement can be written as 40m west.
Therefore,
Velocity = 40 / 45 = 0.89m/s west
5.38
21 divided by 3.9 is 5.38 and the equation for acceleration is change in velocity divided by time
True is the answer to this question I think.
The ocean and the sky provide a clean, flat line where the Earth seems to meet the sky. If you're standing on the beach looking out at the sea, the part of the sea that "touches" the horizon is called the offing
