Question

calculate the area over which force of 72 N is applied thereby exerting a pressure of 9 PA​

Answer 1

Answer:

heya mate...

as we know.. P = F/A

so...A = F/P

= 72N/9Pa

= 8N/Pa

=8Nm^2/N

= 8m^2

hope this helps....

Answer 2

SOLUTION

Pressure= Force/area.

Therefore, area = force /pressure

(you get this formula using Linear equations. Hint:72N/x= 9Pa)

Force= 72N

Pressure= 9Pa

Area= x

Therefore,

x= 72N/9Pa

=) x= 8m^2

hope it helps ☺️
