Answer:
The answer to your question is: number 2 is correct.
Explanation:
Formula
F = m x a
The formula shows that acceleration and mass and inversely proportional, then if the mass increases 3 times, then the acceleration must diminishes 3 times.
1. The object will accelerate the same amount as before because the mass does not affect the object’s acceleration.
This option is incorrect, the acceleration must diminish.
2. The object will accelerate 1/3 as much because if you apply the same net force but increase the mass, the acceleration will decrease. This option is correct, is what i describe above.
3. The object will not accelerate because now it is too heavy.
this option is wrong, because the object will accelerate.
4. The object will accelerate 3 times as much because if you apply the same net force and increase the mass, the acceleration will increase. This option s incorrect, the acceleration will diminish not increase.

<span>How does the modern Periodic Table of the Elements differ from Mendeleev's chart?</span>
Dmitri Mendeleev's periodic table<span> featured </span>elements<span> arranged in accordance with their atomic mass, while the </span>modern table<span> has </span>elements<span> arranged according to </span>periodic<span> number. </span>Mendeleev's periodic table<span> also had the </span>elements<span> arranged vertically, whereas the </span>modern table<span> has them arranged horizontally.

Answer: 94.07%
Explanation:
Percentage yield can be calculated by the formula
%yield = Experimental yield/Theoretical yield x100
Experimental yield = 7.93g
Theoretical yield = 8.43
%yield = Experimental yield/Theoretical yield x100
%yield = 7.93/8.43 x 100 = 94.07%
