The classification of organisms into prokaryotes and eukaryotes is based on which characteristic?

In a $CE$ transistor amplifier,the audio signal voltage across the collector resistance of $2\, k\Omega$ is $2\, V$. If the base resistance is $1\, k\Omega$ and the current amplification factor $(\beta)$ of the transistor is $100$,the input signal voltage is:

An integrating factor of the differential equation $(1-x^2) \frac{dy}{dx} + xy = \frac{x^4}{(1+x^5)} (\sqrt{1-x^2})^3$ is
