Solution
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 |
