Answer: C) Plant photosynthesis decreases

Explanation: An oil spill may impact on various ways, it can be harmful to plants and animals, change the ph of the water (which also affects the wildlife in the water), dangerous emissions, and one thing you need t to have in mind is that these effects may last from 2 to 5 or more years.

Then the two options that made sense are options C and D.

The change in the Ph made by the oil spills is the opposite of the showed in option D, the Ph decreases, which made the water more acidic, so we can discard the option D.

And we end up with option C, plant photosynthesis decrease, this is because the thicker oil blocks the sunlight to the plants underwater, and then there is less sunlight received by them, which affects their photosynthesis.

What will happen to the 0.1 N force if one charges is increased by a factor of 3?
AleksandrR [38]

Answer:

Explanation:

Force between two charges is given by the following expression

F = \frac{KQ_1Q_2}{d^2}  Q₁ and Q₂ are two charges and d is distance between two.

.1 = \frac{KQ_1Q_2}{d^2}

If Q₁ becomes three times , force will become 3 times . Hence force becomes .3 N in the first case.

Force F = .3 N

If charge becomes one fourth , force also becomes one fourth .

F= \frac{.1}{4}

= .025 N.

Suppose the price elasticity of supply for gasoline in the short run is estimated to be 0.4. Due to an unexpected surge in the d
netineya [11]

Answer:

increase by 8 percent

Explanation:

<em>Price elasticity of supply of a product is the degree of responsiveness of supply of that product to a change in price.</em> Simply put:

Price Elasticity of supply = change in quantity supply/ change in price.

In this case, price elasticity of supply of gasoline = 0.4

Percentage price increase = 20 percent.

Hence,

           0.4 = change in supply/20

           Change in supply = 20 x 0.4 = 8 percent

<em>Therefore, the quantity supply of gasoline will increase by 8 percent</em>
