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.

Will give brainliest! which statement best describes the difference between strong nuclear forces and weak nuclear forces? weak nuclear forces are involved when certain types of atoms break down. strong nuclear forces are responsible for holding atoms' nucleus together. weak nuclear forces hold bonds between atoms together. strong nuclear forces hold together the nucleus of an atom. strong nuclear bonds prevent atoms from falling apart. weak nuclear bonds prevent compounds from falling apart. strong nuclear forces are involved in breaking electrons from their shells. weak nuclear forces hold protons in the nucleus.
