A solid weight 5Nin air and 4.2N in water and 4.4N in liquid9.calculate the relative density
The relative density of a substance is defined as the ratio between its density and the density of a reference substance.
To determine the relative density, we need to find the density of both the substance and the reference substance.
Given:
Weight in air = 5N
Weight in water = 4.2N
Weight in liquid = 4.4N
Density of water (reference substance) = 1000 kg/m^3
Density of liquid = ? (let's call it ρ)
To find the density of the liquid, we can use the equation:
Density = Weight / Acceleration due to gravity
The acceleration due to gravity is approximately 9.8 m/s^2.
Density of water = Weight in water / Acceleration due to gravity
Density of water = 4.2N / 9.8 m/s^2
Density of liquid = Weight in liquid / Acceleration due to gravity
Density of liquid = 4.4N / 9.8 m/s^2
Now we can substitute these values into the equation for relative density:
Relative density = Density of liquid / Density of water
Relative density = (4.4N / 9.8 m/s^2) / (4.2N / 9.8 m/s^2)
Calculating, we find:
Relative density ≈ 1.05
So, the relative density of the liquid is approximately 1.05.
