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
Answer:
C.
Explanation:
Higher temperatures leads to higher growth rates this is because, as the temperature increases, the plants have more needs to respire leading to more cellular activities and release of more carbonioxide. The increase in atmospheric carbondioxide and cellular activities leads to increase in plant growth. However, it should be noted that the increase in temperature shouldn't go beyond a certain level as it can also cause adverse effects of crops.
explanation: Synthetic fiber or synthetic fibre (in British English; see spelling differences) are fibers made by humans through chemical synthesis, as opposed to natural fibers that are directly derived from living organisms. They are the result of extensive research by scientists to improve upon naturally occurring animal and plant fibers. In general, synthetic fibers are created by extruding fiber-forming materials through spinnerets, forming a fiber. These are called synthetic or artificial fibers. Synthetic fibers are created by a process known as polymerization, which involves combining monomers to make a long chain or polymer. The word polymer comes from a Greek prefix "poly" which means "many" and suffix "mer" which means "single units". (Note: each single unit of a polymer is called a monomer). There are two types of polymerization: linear polymerization and cross-linked polymerization.
