(a)
(b)
(C)
(d)
2000 Pa
20000 Pa​

Answer 1

Answer:

200 pa can be the answer. i am not conformed

Answer 2

☀︎︎ANSWER☀︎︎

GIVEN:-

FORCE = 30N

AREA = 15cm^2

TO FIND:-

THE PRESSURE

FORMULA :-

$p = \frac{f}{a}$

SOLUTION:-

FIRST WE HAVE TO CHANGE 15cm^2

INTO METERS = 0.15.

NOW ,

$p = \frac{f}{a} \\ \\ p = \frac{30n}{0.15m} = 200p$

WHICH IS THE REQUIRED ANSWER!!
