P= sila : powierzchni
DANE
m=50kg
A=0,5m²

Q=mg
p=Q/A=mg/A=50*9,81/0,5=981Pa

PS

Pa - Pascal=Newton/m²

Witaj
dane m=50kg, g=10m/s2=10N/kg, 0,5m2
szukane p
p = F/S.....ale F = Q = mg
p = mg/S = 50kg*10N/kg/0,5m2 = 1000 N/m2 = 1000 Pa

................pozdrawiam

P=F/S
P=?
m=50kg
g=10N/kg
F=0,5m2

F = Q = mg
p = mg/S = 50kg*10N/kg/0,5m2 = 1000 Pa
