Tiny Spring: A tiny silica bead attached to a strand of DNA can be used to study the mechanical properties ofDNA. The system can be approximated as a mass on a spring constrained to move in one dimension.In one such experiment, a bead of mass 7.8 × 10¬15 kg was attached to a strand of DNA with 1623 basepairs and observed for 720 seconds.(a) If the root mean square velocity of the bead is 7.56 x 10-4 m/s, at what temperature was the experimentcarried out?(b) If the root mean square displacement of the particle is measured to be 1.18 × 10-7m, what is the springconstant of the DNA molecule?

Given, m=7.8×10-15 kgvrms=7.56×10-4 m/s
