fabricated in ISRO lab at room temperature of 30°C. If the radius of all wires in the instrumentwas 0.1 mm (as measured in ISRO lab). If the maximum allowable length (as measured in ISROlab) of any wire is approximatelymeter then find1.22Take7 . (Assume that resistivityand length of gold wire change linearly with temperature)You can use these properties of gold.Resistivity at room temperature= 2.2 × 10–8mTemperature coefficient of resistivity= 0.0032 K–1Linear thermal expansion coefficient= 1.5 × 10–5K–1.17.The network shown consists of an infinite number of cells of emf1and2with correspondinginternal resistances r1and r2respectively A resistor R = 1is connected to the end of thenetwork. If the values of the emfs and internal resistances are1= 1.0 V,2= 2.0 V, r1= 4andr2= 6. If the current flowing through the resistor R is I ampere, then find 10 I.R2r2r112r2r1118.A thin non conducting disc of mass M = 2 kg, charge Q = 2 × 10–2Cand radius1Rm6is placed on a frictionless horizontal plane withits centre at the origin of the coordinate system.
