Question

Complete the following tables.

Mass(Kg)	Volume (m3)	Density(kg/m3)
350	175	-
-	190	4

 

Density of Metal (kg/m3)	Density of water (kg/m3)	Relative Density
	103	5
8.5 × 103	103	-

 

weight(N)	Area (m2)	Pressure(Nm−2)
-	0.04	20,000
1500	500	-

Answer 1

We know, `"Density" = "Mass"/"Volume"`

So, using the above formula, we can find one quantity if the other two quantities are given.

Mass (kg)	Volume (m3)	Density (kg/m3)
350	175	2
760	190	4

We know, Relative density of substances =`"Density of substances"/"Density of Water"`

So, using the above formula, we can find one quantity if the other two quantities are given.

Density of Metal (kg/m3)	Density of water (kg/m3)	Relative Density
5 × 103	103	5
8.5 × 103	103	8.5

We know, Pressure = `"Force"/"Area"`

So, using the above formula, we can find one quantity if the other two quantities are given. 

Weight (N)	Area (m2)	Pressure (N m−2)
800	0.04	20,000
1500	500	3
