LC oscillators have been used in circuits connected to loudspeakers to create some of the sounds of electronic music. What inductance must be used with a 8.7 μF capacitor to produce a frequency of 15 kHz, which is in the audible range of frequencies? please post answer in mH, it keeps telling me I am wrong.

Two electrical oscillators are used in a heterodyne metal detector to detect buried metal objects. The detector uses two identical electrical oscillators in the form of LC circuits having resonant frequencies of 795 kHz. When the signals from the two oscillating circuits are combined, the beat frequency is zero because each has the same resonant frequency. However, when the coil of one circuit encounters a buried metal object, the inductance of this circuit increases by 1.290%, while that of the...
