When calculating net force, we subtract opposing forces, and add together forces going in the same direction! With opposing forces, since you can’t have a negative net force, the smallest force will be subtracted from the largest force!

In the top left corner, an arrow going right is 4N, and an arrow pushing left is also 4N. Because they are equal numbers and in opposite directions, they cancel each other out, for a balanced net force of 0N.

In the bottom left, we have 4N pointed right and 5N pointed left. 5N (largest value) - 4N (smallest value) gives you an unbalanced net force of 1N.

On the top right both forces, 6N and 3N, are pointed in the same direction. Because of this, we add them to get a total 9N net force.

On the bottom right, 7N are going left and 2N are going right. Because they are opposing forces, we subtract 2N from the 7N to get a total of 5N.

Answer from: Quest

estuaries are the partially enclosed coastal bodies of brackish water formed at the mouth of sea where river meets an ocean. it is a transition zone between river and sea water so estuaries are influenced to both marine environment such as tides, waves and to riverine such as flow of fresh water and sediments. the mixing of sea and fresh water provide high level of nutrients, making estuaries a high product habitats.

many estuaries suffers degradation from a variety of human activities like erosion from deforestation, overgrazing, overfishing, drainage and eutrophication.

so from the above statement answers will be

1. false as estuaries are formed due to both brackish and freshwater.

2.true, due to high productivity estuaries are breeding ground for many marine species.

3. direct and indirect activities of man that contribute to pollution and deposition of sediments.
