Respuesta:
340 N/cm²
Explicación:
Paso 1: Información provista
Peso de la estructura (F): 8500 Newton
Area superficial (A): 25 cm²
Paso 2: Calcular la presión (P) ejercida por la estructura de concreto sobre su base
La presión es igual al cociente entre la fuerza ejercida y la superficie sobre la que se aplica.
P = F/A
P = 8500 N / 25 cm² = 340 N/cm²
Gasoline use contributes to air pollution
Gasoline is a toxic and highly flammable liquid. The vapors given off when gasoline evaporates and the substances produced when gasoline is burned (carbon monoxide, nitrogen oxides, particulate matter, and unburned hydrocarbons) contribute to air pollution. Burning gasoline also produces carbon dioxide, a greenhouse gas.

Answer:
A). An atom is an indivisible hard-sphere.
Explanation:
The 'Atomic Theory' of Dalton is characterized as the earliest model(came in 1803) which described the atoms as the indivisible and resistant spheres. He <u>used the example of watermelon to elaborate that the atoms of a specific element share similar characteristics</u> and the atoms of distinct elements differ in their mass as well as their size. Thus, <u>option A</u> is the correct answer.
