17:58 Question 1 (1 points) Consider an under-damped harmonic oscillator, consisting of a mass on a spring oscillating inside a bath of viscous fluid. Which of the following statements is FALSE? Select the correct answer If the drag coefficient (friction with the fluid) O becomes much larger, the system could become overdamped and will no longer oscillate. O The mechanical energy of the mass-on-a-spring is conserved. If the drag coefficient (friction with the O fluid) increases slightly, then the mass X Your will still oscillate but the oscillations will Answer damp out more quickly. O The amplitude of the oscillation will decrease exponentially as time goes on. O The potential energy of the mass goes up and down, with the peaks becoming lower over time.
