The snow shoes have large, flat soles so they exert less pressure (= force /area) on the soft snow and stop the wearer from sinking into it.

What force acting on an area of 0.5m2 will produce a pressure of 500Pa
We know that pressure is the normal force acting per unit area. So,
P = F/A
so the force will be
F = P x A
here
P = pressure = 500 Pa
A = area = 0.5 m2
thus, we get
F = 500 x 0.5
so force is
F = 250 N
P = F/A
so the force will be
F = P x A
here
P = pressure = 500 Pa
A = area = 0.5 m2
thus, we get
F = 500 x 0.5
so force is
F = 250 N

u understand

just wait a min
we know that pressure is the normal force acting per unit area, so P= F/A so, the force will be F=PxA , P =pressure = 500pa, A= area =0.5m2 ,thus, we get F= 500x 0.5 , so force is F =250 N
I think it's help you
u can see the answer
