Answer: left and applied force
Explanation:
Answer:
+9.8m/s^2
Explanation:
The rate of gravity of the object is constant thriughout the surface of the earth.
For falling object, the rate of gravity is positive since the body is coming down (falling)
The rate of gravity is negative if the body is going up
The constant value for acceleration due to gravity is 9.8m.s^2
Since the object is falling, hence the acceleration due to gravity is positive.
Rate of gravity working on the object will be +9.8m/s^2
Answer:

Answer:
because the red and blue regions are the optimum regions for photosynthesis.
Explanation:
Artificial plant-growth lights have a light spectrum that favors the red and blue portions of the spectrum <u>because the red and blue regions are the optimum regions for photosynthesis</u>.
Plants generally need photosynthesis to survive because, during the process, their food is synthesized. The process requires light energy to be absorbed by the green pigment of the plant - the chlorophyll. The light energy excites some electrons of the photosystems of the chlorophyll, leading to the release of the electron. The electron thus travels in an electron transport chain, eventually utilized to generate energy-rich molecules that are later utilized in other parts of the process to manufacture food.
<em>Investigations have revealed that the process of photosynthesis proceeds optimally in the red and light regions of the light spectrum. The discovery has made the manufacturers of artificial plant-growth light to engineer their products to favor more of these two light regions above the rest of the visible light spectrums. </em>
