Question

which is dimensional a specific speed specific volume specific gravity specific weight​

Answer 1

Explanation:

For example, the specific gravity of 0.84 corresponds to the density of 840 (0.84 x 1000) kg/cubic meters. Multiply the density by the acceleration of gravity (9.81) to calculate the specific weight. In our example, the specific weight is 840 x 9.81 = 8,240.4. Measure or obtain elsewhere the volume of the substance.

Answer 2

Explanation:

specific resistance ≅ Resistivity (f) depends on 

the material of the wire and as according 

to the question both wires are of same

material ⇒ resistivity of both wires is same.
