An uncharged molecule of dna (deoxyribonucleic acid) is 2.14 µm long. the ends of the molecule become singly ionized so that there is a charge of −1.6 × 10−19 c on one end and +1.6 × 10−19 c on the other. the helical molecule acts like a spring and compresses 1.4% upon becoming charged. find the effective spring constant of the molecule. the value of coulomb’s constant is 8.98755 × 109 n · m2 /c 2 and the acceleration due to gravity is 9.8 m/s 2 . answer in units of n/m.

K = 1.72 *10^{-11} N/m

Explanation:

given data:

L= 2.14*10^{-6} m

           = 2.99*10^{-8} m

electrostatic force = spring force

putting all equation to get spring constant K value

K = 1.72 *10^{-11} N/m

5 w for 1hr = 5x60x60 joules=300x60=3000x6=18,000j as total energy conversion. efficiency of bulb needed for radiant to thermal within 18000

the answer would most likely be c, because if it's a comical piece of information, it may likely not be true, if it's a site that allows anybody to edit the content, it could mean a five year old is typing the info, and if it's a tv show produced by a celeb, it may have a biased opinion.
