In collateral vascular bundles, phloem is situated towards inner side. In monocot stem, cambium is present.
F particles are present in the inner mitochondrial membrane. An electron gradient formed on the inner mitochondrial membrane, forms ATP
Colloidal solutions are stable but colloidal particles do not settle down. Brownian movement counters the force of gravity actively on colloidal particles.
Ciliated epithelium is present in the inner lining of trachea and large bronchi. Ciliary movement propel the mucus and foreign particle towards the larynx.
Bleaching powder reacts with dilute acids to evolve chlorine. The chlorine liberated by the action of dilute acids on bleaching powder is called available chlorine.
An electric motor will have maximum efficiency when back emf becomes equal to half of applied emf. Efficiency of electric motor depends only on magnitude of back emf.

A car, starting from rest, accelerates at the rate $f$ through a distance $S$, then continues at constant speed for time $t$ and then decelerates as the rate $f / 2$ to come to rest. If the total distance travelled is $15 S$, then
A hollow cylinder has a charge $q\,\, C$ within it. If $ \Phi $ is the electric flux in unit of voltmeter associated with the curved surface $B$, the flux linked with the plane surface $A$ in unit of voltmeter will be
