Li2O
Lithium is a metal with an oxidation number of 1+ and oxygen is a nonmetal with an oxidation number of 2-. Which chemical formula represents the compound formed by these two elements? Li2O is the correct answer because lithium has one valence electron and oxygen has six.
Hope this helped.
When a dielectric material is inserted between two plates of capacitor that are connected to a battery, you would observe that both the charge and the capacitance of the capacitor would change. This is due to the dielectric material which is able to transmit electric force.
Vf = Final velocity.
Vi = initial velocity
a = acceleration.
t = time
Vf = Vi + at
Vf = 0 + (2 m/s^2)(3s)
Vf = 6 m/s south
Here’s 3 examples:
MCB is more sensitive to current than fuse.
In case of MCB, the faulty zone of electrical circuit can be easily identified.
With MCB it is very simple to resume to the supply.

Hi there!
We can use the following equation to relate angular velocity to linear velocity.
v = linear velocity (m/s)
ω = angular velocity (3.46 rad/sec)
r = distance from axis of rotation (.12 m)
Plug in the given values.
