Q1. For a damped oscillator with a mass of 280 g, a spring constant 140 N/m and a damping coefficient of 74 g/s, what is the ratio of an amplitude of the damped oscillations to the initial amplitude at the end of 17 cycles?
Q2. Light of wavelength 588 nm falls on a double slit. First-order bright bands appear 3.65 cm from the central bright band. The screen is 1.20 m from the slits. How far apart are the slits?
