Answer:
The correct answer is: 1.316 . 10⁻³ m³/kg.
Explanation:
The density (ρ) of a substance is the ratio of its <em>mass (m)</em> to its <em>volume (V)</em>. At constant temperature and pressure, its value is constant and it is an intrinsic property of materials. The units of density are kg/m³.
The specific volume (ν) of a substance is the ratio of its <em>mass</em> to its <em>volume</em>. We can see that it is the reciprocal of density and an intrinsic property of matter as well. Therefore, the units of specific volume are m³/kg.
Given we know the density of the liquid, we can use this relationship to find out its specific volume:

<u>Given:</u>
Velocity of the dog, v = 5.4 m/s
Centripetal acceleration, a = 48.6 m/s2
<u>To determine:</u>
Radius of the path
<u>Explanation:</u>
The centripetal acceleration is related to the velocity and radius as:
a = v²/r
r = v²/a = (5.4 m/s)²/48.6 m/s2 = 0.6 m
Ans: Radius of the path is 0.6 m
