Answer:The newly formed oxygen ion is negatively charged.
Explanation:
Cation : These are species of ions which carries positive charge that is number of protons are greater than the number of electrons.
Anion:These are species of ions which carries negative charge that is number of electrons are greater than the number of protons.
When an oxygen atom gains two electrons it develops the charge of negative charge and forms anion.
Answer:
0.05s
f=20Hz
we know,
time period=t=1/f
t=1/20
=0.05s
d
i think it is rotational inertia
because analogue of mass in rotational motion is moment of inertia. It plays the same role as mass plays in transnational motion.
hope it's right & helps !!!!!!!!!
