When we say toolmark, this describes as the mark that is produced by a particular tool. This is typically used in forensic science for identification. Based on the examples above, the one that is not the proper use of casting of a toolmark is option B. Hope this helps.
If the ice absorbed 350,000 joules in 5 minutes, then it absorbed energy
at the rate of
(350,000 joules) / (5 x 60 seconds) =<em> 1,166-2/3 watts</em> .
Surely the ice cube didn't absorb every joule delivered to the cooking chamber,
so the microwave oven's cooking power had to be significantly more than that.
Answer: it becomes a positive ion
Explanation:
So, when an atom loses 2 electrons there will be no change in the number of neutrons. Therefore, an isotope will not form. Thus, it is concluded that when an atom with no charge loses two electrons, it becomes a positive ion.
False. What actually determines the properties of elements are the electrons, or aka valence electrons. They are used to bond, which determines its properties.
