Question

A.

Answer 1

Answer:

A) Option 1 is the correct answer.

B) Option 4 is the correct answer.

Explanation:

A) Weight of liquid = 7 N

    Volume of liquid = 1 L = 0.001 m³

    Specific weight =  $\frac{7}{0.001}=7000N/m^3$

    Density = $\frac{7000}{9.81}=713.5kg/m^3$

    Specific gravity = $\frac{713.5}{1000}=0.7135$

    Option 1 is the correct answer.

B) The Stokes(St) is the cgs physical unit for kinematic viscosity, named after George Gabriel Stokes.

We have

             1 St = 10⁻⁴ m²/s

    Option 4 is the correct answer.
