The resonant frequency is set by the L and the C: 900 microhenrys and 0.014 microfarad would resonate at a frequency given by:
F = 1/ [2 pi sqrt(LC)]
If the components are in 'micros' the answer is in Megahertz.
In this case the resonant frequency in MHz is:
F = 1/ [2 pi sqrt(900 x 0.014)] or 0.0448 MHz, 44.8 kHz.
The reactance of the inductor and the capacitor is 253 ohms, so adding a 1000 ohm resistor in parallel would give a tuned circuit with a Q of 1000 / 253 or 3.9.
