Who exerts more pressure? a) A girl of 50 kg, wearing heels with an area of 1 cm2. b) An elephant of 4000 kg with foot area of 2

Mrrafil [7]

Answer:

The girl exerts more pressure.

Explanation:

Pressure can be defined as the force exerted normally or perpendicularly per unit area.

i.e P = F/A

Girls

Area of the heel = 1cm² = 10^(-4) m²

Force = mg = 50 × 10 = 500N

Pressure =

$\frac{500}{10 ^{ - 4} }$

$= 5 \times {10}^{6}$

Elephant

Area = 250cm² = 2.5 x 10^(-2)b m²

Force = mg = 40000N

Pressure =

$\frac{40000}{2.5 \times {10}^{ - 2} }$

$= 1.6 \times {10}^{6}$

In order from largest to smallest these terms are:UniverseGalaxySolar systemStarPlanetMoonAsteroidWe can generally say that a Moon is larger than an asteroid however some moons are quite large while others are smaller than many known asteroids. Asteroids are small rocky bodies that orbit the Sun, while moons are objects that orbit planets. Jupiter and Saturn have attracted many objects out of the asteroid belt and gathered them as moons.
