Question

The elephant weighs 20000 N stands on one foot of area 1000 cm² how much pressure would it exert on the ground

Answer 1

Explanation:

forcE=20000N

area=1000cm^2 =1000/100=10m

it is done because newton is SI unit while cm is CGS unit

so I converted cm in SIunit (m)

so, pressure=force/area

pressure=20000/10

pressure=2000Pascal

(Pascal is SI unit of pressure)

please make this brainless answer and rate best

Answer 2

Pressure = F/a (Force / unit area)

→20000 × 10

= 200000 n/m²

= 200000pa (pa means pascals)
