Question

how much pressure is applied on a girl of 40 kg if she is standing on both Feet and area umder one feet is 8cm square?
i will give brainlist to first answer..​

Answer 1

Answer:

pressure = force/area

force = 40kg

         =[40*10]N

         =400N

area = 8cm = 8/100*100 metre square = 0.0008 metre square

pressure = 400/0.0008 pascal

               =4000000/8 pascal

               =500000 pascal
