Which is a man-made element? All elements with atomic numbers 1 through 94 occur naturally at least in trace quantities, but the following elements are often produced through synthesis. Technetium, promethium, astatine, neptunium, and plutonium were discovered through synthesis before being found in nature. Is technetium man-made? Technetium was actually discovered — produced artificially — […]

¿Cuáles son las formas en que viaja el sonido? Las ondas sonoras entran al oído externo a través de un pasaje estrecho llamado “conducto auditivo” que llega hasta el tímpano. El movimiento de las ondas sonoras hace que el tímpano vibre y a la vez transmita estas vibraciones a tres huesecillos diminutos del oído medio. […]

Is observation method qualitative or quantitative? Qualitative observation gathers data samples using complete observer, observer as a participant, participant as an observer and complete participant methods while quantitative observation collects data samples using surveys, questionnaires, and polls.
