5. which is not a likely component of a physics experiment? sc.7.n.1.5\na developing a mathematical description of the experiment\nb conducting a public opinion poll on the topic of the experiment\nc repeating the same procedure a large number of times\nd speculating about what the outcome of the experiment might be\n6. how can an extinction occur quickly? sc.7.l.15.3\na species are hunted to extinction.\nb a natural disaster wipes out an entire species.\nc mountains create a geographic divide separating a species from its resources.\nd climate changes eliminate the food sources of a species.\n7. why is the inner core of earth a solid? sc.7.e.6.1\na the pressure on the inner core is so great that even substances at 6,000°c remain solid.\nb the temperature of the inner core is very cold so it remains a solid.\nc the pressure of the inner core pushing against the mantle keeps it solid.\nd the inner core is made of solid metal and is impossible to melt.

Answer

# Brief Explanations: - **Pregunta 5**: Un experimento de física implica la descripción matemática, la repetición para la confiabilidad y la especulación sobre los resultados. Un sondeo de opinión pública no es parte de un experimento de física. - **Pregunta 6**: La caza masiva de especies puede llevar a la extinción rápidamente. Un desastre natural puede hacerlo, pero no siempre afecta a toda una especie. Las montañas y los cambios climáticos son factores más graduales en la extinción. - **Pregunta 7**: La gran presión en el núcleo interior de la Tierra hace que las sustancias permanezcan sólidas incluso a altas temperaturas. # Answer: - 5. B. conducting a public opinion poll on the topic of the experiment - 6. A. Species are hunted to extinction. - 7. A. The pressure on the inner core is so great that even substances at 6,000°C remain solid.
