Question

what is a scale factor 2/3?

Answer 1

1.345

Resistance of a metal wire of length 2m is 14 ohm at 20 degree Celsius if the diameter of the wire is 0.6 millimetre what will be the resistivity of the metal at that temperature

Answer 2

Answer:

Scale factor=2/3

»∆ABC/∆PQR=2/3. (Let)

»AB/PQ=2/3

Therefore,AB:PQ=2:3
