Answer:
If you have something like an endoscope except controlled remotely doctors and healthcare workers could in essence use it as a sort of reconnoissance tool for diagnosing injuries and illnesses.
Explanation:
For radioactive decay:
N = N(0) x exp(-λt), where λ is the decay constant equivalent to ln(2)/half life, N is the amount after a given amount of time, t is the time passed and N(0) is the initial amount.
1)
N = 24 x exp(-ln(2)/4.5 x 36)
N = 0.09375 mg
2)
1.2 = 9.6 x exp(-ln(2)/4.5 x t)
ln(1.2/9.6) = -t x ln(2)/4.5
t = 13.5 days
Answer:
The Red Cabbage Indicator can determine the PH based on what color the solution turns into.
Explanation:
Very acidic solutions will turn anthocyanin into a red color. Neutral solutions result in a purplish color. Basic solutions appear in greenish-yellow. Therefore, you can determine the pH of a solution based on the color that it turns the anthocyanin pigments in red cabbage juice.
