Answer:
4900 J
Explanation:
Potential energy is the product of the mass, gravitational constant and the height of the object.
U=mgh=10 kg×9.8 m s^(-2)×50 m=4900 J
So, the potential energy of the object is 4900 J.
The right answer is A. An impact of changing scientific knowledge on society

<u>Answer:</u>
<em>In highly diverged lineages, the substitutions process will occur at sites that have been substituted previously</em>.
<u>Explanation:</u>
Molecular clock uses the mutation rate to reduce the time in prehistory when the life forms are diverged. <em>The molecular clock uses the sequence of amino acids and nucleotide sequence for the DNA.</em>
This clock does not measure any time but the number of mutations, and other changes over certain time. <em>Sometimes its useful property might be limited due to the highly diverged lineages.</em>
