An electric device delivers a current of [tex]$15.0 A$[/tex] for 30 seconds. How many electrons flow through it?
Answer (2)
The statement 'Primatologists are always trained as biologists' is False .
Primatology is the scientific study of primates, a group that includes monkeys, apes, and humans among other species. While many primatologists have a background in biology, especially since understanding biological processes and evolution is crucial for studying primates, not all primatologists are trained specifically in biology.
Here's why:
Diverse Academic Backgrounds : Primatologists can come from various academic backgrounds, including anthropology, psychology, zoology, and even conservation science. This is because primatology can involve studying primate behavior, social structures, cognition, and their interactions with the environment.
Interdisciplinary Field : Primatology is an interdisciplinary field. While biological training is beneficial, some primatologists focus on the behavioral aspects of primates, which can be studied through an anthropological or psychological lens.
Research Methods : The field involves both fieldwork and lab work, requiring different skills. Field primatologists, for instance, often work in natural environments, and their training might prioritize understanding ecosystems and field survey methods over biology alone.
Thus, while biological knowledge is a significant component of primatology and essential for certain aspects of the field, it is not a mandatory requirement for all primatologists.
When a current of 15 A flows for 30 seconds, it delivers a total charge of 450 coulombs. Since each electron carries a charge of about 1.6 × 1 0 − 19 coulombs, approximately 2.81 × 1 0 21 electrons flow through the device. Thus, a significant number of electrons travel through, indicating how electric current works on a microscopic level.
