F = m.a
F = 3(2 I + 5 j)
F = 6i + 15j is resultant force
Magnitude force = √6+15 = √21
Answer:
Elastic potential energy is stored when materials stretch or compress. Examples of it include springs, rubber bands, and slingshots.
Explanation:
Given what we know, we can confirm that doubling the distance between you and a source of radiation decreases your exposure by 75%.
<h3>How is distance related to radiation exposure?</h3>
- As expected, increasing the distance from the source of the radiation will reduce its negative effects.
- Counter-intuitively however, doubling the distance does not reduce by half, but rather reduces its effects by 3/4th.
- This is due to the fact that the radiation effects from the source are inversely proportional to the square of the distance.
- This causes the changes to be far greater than expected.
Therefore, given that the radiation is proportional to the square of the distance, instead of being of a more direct relation, we can confirm that when doubling the distance between yourself and the source of the radiation, you can reduce its effects by 3/4 or 75%.

What is not the ultimate goal of science is to produce unchanging and absolute answers - D. Scientists would like to, however, understand patterns, give explanations for natural events, and even make predictions. And it isn't really the case that they would like to produce unchanging answers.
I tried dude, but someone got rid of my helpful resource...<span />
