Answer 1

$Question$

A force of 20N acts on an area of 50 cm² Calculate the value of pressure in pascal.

$Solution$

$<font color=purple>$

Force= 20N

Area=

${50cm}^{2}$

=

${0.005m}^{2}$

P= N/m^2

P=

$\frac{20}{0.005}$

$answer \: \: is$

4000 Pa

Hope it helps...

Answer 2

$\huge\bold{\underline{{Question:}}}$

1)Convert 50 cm² into m or m².

2)A force of 20N acts on an area of 50 cm². Calculate the value of pressure in pascal.

$\huge\bold{\underline{{Answer:}}}$

➠Answer 1:

➤We know that:

1² cm = 100 m²

⇉So, We multiply the area value by 100.

50 cm² = 5000 m².

➠Answer 2:

➤Given:

Force = 20N

Area = 50cm² = 0.005 m²

➤To find :

⇉Pressure in pascal.

$pressure = \frac{force}{area} \\ = \frac{20}{0.005} = 4000 \: pa$

⇉So the value of pressure in pascal = 4000 pa.
