The free body diagram consists of:

1) Weight force, which is a vertical arrow downward

2) A Normal force that is perpendicular to the ramp.

The Normal force can be decomposed in a vertical component and an horizontal component.

The vertical component, Ny,  must equal the weight force, due to equilibrium (rest) condiition =>

Ny = weight = m*g = 5.5kg*9.8m/s^2 = 53.9 N

By geometry the vertical component of the Normal force, Ny is such that

cos (angle) = N / Ny => N = Ny * cos(angle)

=> N = 53.9N * cos(angle)

Now use that equation for each option:

a) 0 ° => N = 53.9N * cos(0) = 53.9N

b) 12° => N = 53.9 * cos(12) = 52.7N

c) 25° => N = 53.9 * cos(25) = 48.9N

d) 45° => N = 53.9 * cos(45) = 38.1N

Meandering caused the two oxbow lakes to be formed.

Explanation:

There are multiple different types of lakes, and the type of a lake is determined by the manner in which it has been formed. One of the lake types is the oxbow lake. This type of lake form from the preexisting meanders of the rivers, and they are located right next to a river, usually being separated by the river by only few meters.

When a river is meandering, which happens in flat terrain where the river is slow, it gradually takes up a snaky shape. This type of shape of the river can only go a certain point, till about 90 degrees angle of curvature. Once this angle is reached, the water starts to erode the sediment as it finds it hard to curl. Over time, the sediment is totally eroded, and the river continues in a straight line, cutting off the water to meandering parts, and separating itself from them. This results in the formation of oxbow lake, which is a bow-like, shallow lake.

Other types of lakes are:

  • tectonic
  • volcanic
  • organic
  • glacial
