The toxic runoff from the farms will directly enters the water bodies of the earth through the drainage system.
The emissions from the cars will go into atmosphere and will react with water and then it will enter the earth's water. So, it is not directly affecting the earth's water.
The dumping trash on roadsides do not enter the earth's water. It can enter the earth's water through rains.
The production of oxygen by trees is not pollution.
Hence, option (A) is correct.
A single replacement reaction occurs when two different cations switch places to combine with the same anion. One element forms a compound while another element is released from the compound. In a single replacement reaction, or single displacement reaction, a single<span> uncombined element replaces another in a compound.
So you're answer is probably c.

Answer:
F = 29.64 × 10-¹¹N
Explanation:
From newton's law of gravitation which states that every object in the universe will attract each other with a force which is directly proportional to the product of their masses and inversely proportional to the square of their distance apart.
That is, F = (Gm1m2)/ r²
From the question m1=4kg, m2 = 2.5kg, r= 1.5m,G = 6.67×10-¹¹
F=( 6.67×10-¹¹ × 4 × 2.5) / 1.5²
F = (66.7×10-¹¹) / 2.25
F = 66.7/2.25 × 10-¹¹ N
F = 29.64 × 10-¹¹N
F = 29.64 × 10-¹¹N

<span>When we see a solid color that is red, blue, or black let's say, it is said to have a high saturation of color. A color that is almost gray has very little or very saturation. Of course, the amount of gray can vary greatly but for the most part a color that is almost gray has little or no saturation at all.</span>
