Answer:
pretty sure u did it right??
<h2>Answer : 1 is gamma, 2 is alpha and 3 is beta radiations.</h2><h3>Explanation :</h3>
In the given information all the radiations were stopped by the lead block, if we assume that first radiations were gamma radiation, as they were not stopped by the cloth whereas all other radiations were stopped.
In second case, aluminum foil and wood were able to block alpha and beta radiations. Whereas, paper was used to stop the alpha particles but not the gamma and beta rays. And then a thick concrete stopped all the radiations.
This clarifies that the first radiation are gamma rays, second is alpha rays and third is beta rays.
Answer: hey nice to see you again, the answer is B. Microscopes allowed scientists to see the cells.
Explanation:
Answer:
0.025M
Explanation:
As you must see in your graph, each concentration of the experiment has an absorbance. Following the Beer-Lambert's law that states "The absorbance of a solution is directely proportional to its concentration".
At 0.35 of absorbance, the plot has a concentration of:
<h3>0.025M</h3>
