You need to produce a set of cylindrical copper wire 3.5 m long that will have a
vazorg [7]

Solution :

We know, resistance is given by :

R = \dfrac{\rho l}{A}

A = \dfrac{\rho l }{R}\\\\A = \dfrac{1.72\times 10^{-8} \times 3.5 }{0.125}\\\\A = 4.816 \times 10^{-7} \ m^2

Now, we know mass of wire is given by :

Mass = Density \times Volume\\\\\M = 8.9 \times 10^3 \times 4.816 \times 10^{-7} \times 3.5 kg\\\\M = 0.01500\ kg\\\\M = 15.00\ gram

Hence, this is the required solution.

Explanation:

A basic quantity is basically the physical quantity that can not be defined in terms of other quantities.

Some of the names of the basic quantities include:

  1. Mass, denoted by the symbol 'm', with S.I. unit 'kg'
  2. Length, denoted by symbol 'l', with S.I. unit 'm'
  3. Time, denoted by symbol 't', with S.I. unit 's'
  4. Current, denoted by 'I', with S.I. unit 's' 'A'
  5. Temperature, denoted by 'T', with S.I. unit 'K'
  6. Amount of substance, denoted by 'n', with S.I. unit 'mol'
  7. Luminous Intensity, denoted by 'Iv', with S.I. unit 'cd'

  • A basic quantity is chosen arbitrarily.
