An oxygen atom at a particular site within a DNA molecule can be made to execute simple harmonic motion when illuminated by infrared light. The oxygen atom is hound with spring-like chemical bond to a phosphorus atom, which rigidly attached to the DNA backbone. The oscillation o the oxygen atom occurs with frequency f = 3.7 × 10 13 HZ. If the oxygen atom at this site is chemically replaced with a sulfur atom, the spring constant of the bond i unchanged (sulfur is just below oxygen in the Periodic Table) Predict the frequency for a DNA molecule after the sulfur substitution.

Definition Definition Special type of oscillation where the force of restoration is directly proportional to the displacement of the object from its mean or initial position. If an object is in motion such that the acceleration of the object is directly proportional to its displacement (which helps the moving object return to its resting position) then the object is said to undergo a simple harmonic motion. An object undergoing SHM always moves like a wave.
Steel train rails are laid in 13.0-m-long segments
placed end to end. The rails are laid on a winter
day when their temperature is -6.0° C.

Part B
If the rails are originally laid in contact, what is the stress in them on a summer day when their temperature is
32.0°C?
Express your answer in pascals. Enter positive value if the stress is tensile and negative value if the
