Question

Calculate the pressure exerted by a book of
size 10 cm x 20 cm if the mass of the book is
100 g.​

Answer 1

We know that:

$pressure = \frac{force}{area}$

We know that:

$f = ma$

Therefore Force =0.1kg*9.81m/s^2

=0.981N

Therefore area=10cm*20cm

=0.1m*0.2m

=0.02m^2

Therefore Pressure=0.981N/0.02m^2

=981/20

=49.05N/m^2

=49.05Pascals

Answer 2

Answer:

10 ×20 IS EQUAL 100

Explanation:

IT IS WRONG THEY DO NOT KNOW MULTIPLICATION THE ANSWER WILL BE 10 ×20 = 200
