Q. For a damped oscillator with a mass of 240 g, a spring constant 59 N/m and a damping coefficient of 75.00 g/s, what is the ratio of the amplitude of the damped oscillations to the initial amplitude at the end of 12 cycles?
Q. A parallel plate capacitor has plates of area 2.0x10^-3 m^2 and a plate separation of 1.0x10^-4 m. Determine the capacitance of this system if air fills the volume between the plates.
