Answer 2

Answer:

196000 pa

Explanation:

Pressure=?

Mass= 50 kg

        Pressure= Mass X Acceleration

                       =50 X 9.8 m/s^2 (since acceleration is not given we will take gravity)           =490 N  

Side of cube= 5 cm

          Area=5 x 5 cm^2=25 cm^2

Now we will convert it into m^2

              =25/1000 =25 X 10^-4 m^2  

Pressure=F/A

             =490/25 X 1 0^-4 m^2

              =19.6/1 0^-4 (490/20)    

             =19.6 X 10^4

              =19.6 X 1000

             =196000 pa
