Suponga que la joven del ejercicio anterior usara zapatos con tacones muy agudos. Considere el área de la base de cada tacon igual a 1 cm2, y que la mitad del peso de la joven se distribuye sobre los tacones. a) ¿Qué presión ejercen estos sobre el suelo?

b) Compare la respuesta de (a) con los resultados obtenidos en el ejercicio anterior, y explique por qué los tacones muy delgados causan estragos en los pisos de madera

i think the answer would be b

the aurora is formed when charged particles emitted from the sun during a solar flare penetrate the earth's magnetic shield and collide with atoms and molecules in our atmosphere. these collisions result in countless little bursts of light, called photons, which make up the aurora.

auroras are generated by charged solar particles hitting molecules in earth's atmosphere. this usually happens in high latitudes, because our planet’s magnetic field tends to funnel these particles toward the poles. that’s why it can be experienced in northern ohio.

in most common fires, oxygen is needed for an oxidation reaction to takes place. the combination of oxygen with any element as fuel can create fire and combustion will occur especially if wood, light materials and other combustible things are combine with oxygen.
