Question

58. (a) Define pressure
(b) What is the relation between
between pressure, force and are ?
Calculate the pressure when a force of 200 N is exerted on an area of
(i) 10 m2
(in) 5 m2

Answer 1

Answer:

see the explanation

Explanation:

a) it Is the force applied for unit area.

b) pressure=force /area.

1) p=f/a

=200/10

=20 pascals

2) p=f/a

= 200/5

=40 pascals

hope this is useful. Mark me as brainlist and Rate me if it is useful.

Answer 2

Answer:

a) force applied per unit area is called pressure.

b) Pressure is inversally proportional to Area

Pressure is directly proportional to Force applied

P =F/A

C)( i) Pressure=f/a

=200/10 = 20 Nm^-2

(ii) pressure=200/5=40 Nm^-2
