What property of objects is best measured by their capacitance?

Explanation:

The capacitance is defined as the relationship between the electric charge of each conductor and the potential difference between them. That is, it is the capacity of a device to store electrical charge.  

In other words:  

It is the property that bodies have to maintain an electric charge.  

Mathematically it is defined as:  

where:  

is the capacitance value of a capacitor. Its unit is Farad ; named in honor of the physicist Michael Faraday  

is the electric charge of the conductor, measured in coulombs .  

is the electric potential to which the conductor is located, measured in Volt.  

Explanation:

By definition, the density of the substance is given by:

D = \frac{m}{V}D=

V

m

Where,

m: mass of the substance

V: volume of the substance

Calculating the volume of the substance we have:

V = (50) * (10) * (30) V = 15000 cm ^ 3V=(50)∗(10)∗(30)V=15000cm

3

Then, replacing values we have:

D = \frac{3300}{15000}D=

15000

3300

D = 0.22 \frac{g}{cm^3}D=0.22
