Question

who exerts more pressure . a) A girl of 50 kg wearing heels with an area of 1cm2 . b) An elephant of 4000 kg with foot area of 250 cm2​

Answer 1

Answer:

Let's find out who will exert more pressure.

pressure=force/area.

to convert weight to force multiply by acceleration due to gravity (g).

50*10=500N

4000*10=40000N

first case

p=500/1 N per cm square

second case

p=40000/250

=160 N per cm square.

therefore girl of 50kg wearing heels will exert more pressure so girl exert more pressure than elephant..
