Describe possible relationship between urban population density and urban runoff

jeyben [28]

Answer:

As described below.

Explanation:

There exists a relationship with the amount of agricultural runoff and the population density of the region and the large agricultural lands have a population of just rural people most of the runoff comes from the crops in the form of pesticides and insecticides.

these are dangerous chemicals and harmful substances that indirectly impact the soil fertility and water quality of the nearby streams and river systems. The urban runoff has several criticisms as it is untreated and wastewater that enters the river and destroys their BOD levels by nitrification and contamination.

The urban population has more air pollution than the surface runoff and the urban areas don't have large bodies of water like lakes or seas but the rivers are highly polluted by the effluent emitted by the untreated industrial waters.

Both this runoff affects human health which can be seen in urban flooding and problems of drainage systems in cities.

11 Three forces are acting upon the box shown in the diagram below.

mars1129 [50]

Based on the image shown and attached, assuming there is no friction between the floor and the ground, "these forces will cause the box to move to the left."

The image shows that the highest force, 60N, is on the right, pushing the load to the left.

The force on the left is 40N lower than the force on the right.

The force exerted on the object's body downward is 29N, and it is lesser than the force on the right pushing the load to the left.

Hence, in this case, it is concluded that the correct answer is option A. "The forces will cause the box to move to the left."
