Question

Calculate the pressure exerted by 1.2 m vertical length of density 0.80 g/cm³ [ g = 10 m/s² ]​

Answer 1

Given:

• Density = $\sf 0.80 g/cm^3$

• Length = 8 meter

• g = 10 m/s²

To Find:

• Pressure pressure exerted by 1.2 m vertical length of density 0.80 g/cm³

Solution:

We know that,

$\qquad{\boxed{\red{\bf 1 g/cm^3 = 1000 \: kg/m^3}}}$

$\longmapsto \sf Density \: = \: 0.8 \times 1000$

$\longmapsto \sf Density = 800 \: kg/m^3$

Now,

$\qquad{\large{\boxed{\red{\bf hdg}}}}$

$\longmapsto \sf Pressure = 0.8 \times 1200 \times 10$

$\longmapsto {\purple{\bf 9600 \: Pka}}$

$\therefore$ The pressure exerted by 1.2 m vertical length of density 0.80 g/cm³ is 9600 Pka.
