Question

7

If pressure, measured in pascals, is equal to the force of
an object in newtons divided by the contact area in
square
meters, which of the following combinations of force and
area creates closest to 10,000 pascals of pressure?
A) 200,000 N and 20,000 m²
B) 20,000 N and 10,000 m²
C) 5,000 N and 5 m²
D) 2,000 N and 0.2 m²

Answer 1

`\huge\green{\overline{\underline{\rm{\purple{꧁⫷ᴀɴsᴡᴇʀ⫸꧂ }}}}}`

`\sf {P = (Force)/(Area)}`

`\sf{ P = (2000)/(0. 2)}`

`\sf \green {{{ P = 10000Pa}}}`

Answer 2

2000N and 0.2m^2

Verification:-

• Force=2000N
• Area=0.2m^2

`\\ \sf\longmapsto Pressure=(Force)/(Area)`

`\\ \sf\longmapsto Pressure=(2000)/(0.2)`

`\\ \sf\longmapsto Pressure=10000Pa`
