Whether you can describe physical principles of operation of the RC-oscillator
(capacitance-resistance oscillator) from a point of view of a resonance?

Although a capacitor stores energy an RC circuit is not a
resonant system. The voltage and current in an RC circuit
decay exponentially and have no natural oscillation. The
differential equation is first order while resonance
requires second order.

To make an oscillator using an RC requires a separate
non-linear gain stage (a 'relaxation' oscillator) or you
need multiple RC stages.
