Answer:
1. Wave period = 0.962 s
2. Will absorb red and blue and reflect green
Explanation:
1.
The wave period is:
Wavelength is the distance between crests. So replacing the given information:
2. In simple words the color of an object is the light it reflects. A green object reflects green light, and the rest is absorbed (red and blue).
Light intensity is the "amount of light given off a light source." Also, is the measure the wavelength of the amount of light given off by a light source.
Hope this helps.
Answer:
TIME he applied the fertilizer to each plant
Explanation:
Independent variable in an experiment is the variable that is subject to change or manipulation by the experimenter. In this experiment, Bob wanted to investigate the effects of plant fertilizer. Bob sets up the experiment by applying the fertilizer to each plant at DIFFERENT TIMES i.e. plant 1-every morning, plant 2-once a week, plant 3-never.
Based on this, it is obvious that the independent or manipulated variable is the TIME at which he applied the fertilizer. On the other hand, the dependent or measured variable is the height of the plants.
Answer:
a = 2d / t²
Explanation:
d = ½ at²
Multiply both sides by 2:
2d = at²
Divide both sides by t²:
a = 2d / t²
<span>Notice for the Carbon question they were the same element and the shared the same number of protons. so i think d. is the answer</span>
