Answer:
The brick exerts a pressure of 1000 Pascal on the ground
Step-by-step explanation:
We have :-
→ Length of the brick = 16 cm
→ Width of the brick = 5 cm
→ Thickness = 5 cm
→ Weight (Force) = 8 N
______________________________
Firstly, let's calculate the contact area of the brick
⇒ Area = Length × Breadth
⇒ Area = (16 × 5) cm²
⇒ Area = 80 cm²
Now, let's convert the unit of area from cm² to m² .
⇒ 1 cm² = 0.0001 m²
⇒ 80 cm² = 80(0.0001)
⇒ 0.008 m²
______________________________
Finally, pressure exerted by the brick on the ground will be :-
Pressure = Force/Contact Area
⇒ Pressure = Weight/Contact Area
⇒ Pressure = 8/0.008
⇒ Pressure = 8000/8
⇒ Pressure = 1000 Pa
