Question

5. Complete the following tables. 350 175 190 Mass (kg) / Volume (m') Density (kg/m) 4 Relative Density of Density of Metal (kg/m) water (kg/m) Density 103 8.5 x 103 103 5 Weight (N) Area Pressure (Nm) (m) 0.04 20,000 1500 500 The density of a metal is 10.8 x 103 kol.​

Answer 1

We know, Density=
Volume
Mass
​

So, using above formula, we can find one quantity if other two quantities are given.
Mass (kg) Volume (m
3
) Density (kg/m
3
)
350 175 2
760 190 4
We know, Relative density of
Substances =
Densityofwater
Densityofsubstances
​

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

We know, Pressure =
Area
Force
​

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