_____is currently used as a tyre cord.

A resistance R is connected to a cell of EMF E and has an internal resistance r as shown in the figure. The voltage across R is measured using and ideal A voltmeter and circuit current is measured by an ammeter. A rheostat of negligible resistance is used to vary the current in the circuit. -Write down the expression for current in the circuit and voltage across R at any instant.

The characterstics features of certain polymers are summarised below: Polymer A : Flexible, inert to solvents, used for making non-stick utensils. Polymer B- Hard, high melting used for making synthetic wool, carpets etc. Polymer C: Strong, Fibrous, used for making tyre cords, ropes etc. Give the monomers of A, B and C
