Please give me the answer it is urgent..​

Answer 1

Answer:

1800 N/m^2

Step-by-step explanation:

Pressure = Force/Area

Here, Force = Mass x Acc due to gravity

                    = 45 x 10 N

                    = 450 N

Area = O.5 m x 0.5 m

        = 0.25 m^2

Therefore, Pressure = 450/0.25 N/m^2

                                  = 1800 N/m^2
