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%.

Answer:
C. Electrons are both gained and lost
Answer:
The amount saved in a year is $ 278.6.
Explanation:
current, I = 0.275 A
Voltage, V = 120 V
cost = $ 0.20 per kWh
The energy spent in 1 year is given by
E = V I t
E = 120 x 0.275 x 365 x 24 x 3600
E = 1.04 x 10^9 J
1 kWh = 3.6 x 10^6 J
So,
E = 288.9 kWh
So, the cost is
C = $ 0.2 x 288.9 = $ 57.78
So, the amount saved = $ 336.384 - $ 57.78 = $ 278.6
