<span>They are composed of similar materials: DNA is a deoxyribonucleotide polymer while RNA is a ribonucleotide polymer. A nucleotide is composed of a nitrogenous base, a sugar, and a phosphate group. In ribonucleotides, the sugar is ribose, while in deoxynucleotides, the sugar is deoxyribose. Adenine, guanine, and cytosine are nitrogenous bases in both DNA and RNA, while thymine is found only in DNA and uracil is found only in RNA.</span>
200J
Explanation:
Given parameters:
Force on boulder = 100N
Distance moved = 2m
Unknown:
Work done = ?
Solution:
Work done on a body is the force applied to move such body in the direction of the force.
Work done = force x distance
Input the parameters in the equation:
Work done = 100 x 2 = 200Nm or 200J
The work done in lifting the boulder is 200J
