a girl weighing 50kg is standing on pencil heels, each having an area of cross-section of 1cm. A elephant weighing 200kg and foot area of cross section of 250 cm standing on the floor which exerts more presure on the floor calculate the pressure exerted by her on the floor. show your work along with the answer
Answers
Answer:
Girl is exerting more pressure. Girl is exerting 250000 Pa while elephant is exerting 2000 Pa.
Explanation:
Pressure= Force/Area
Force/Area for girl= 50kg*100*100/2 as 1 m^2=100*100 cm^2 and the girl has 2 legs. Final pressure= 250000 Pascals.
Similarly for elephant, 200kg*100*100/250*4= 2000 Pascals.
So, girl is exerting more pressure, I know this sounds weird, but the girl really is exerting more pressure than the elephant.
Hope it helps, pls mark me as brainliest.
