Explanation:
The unequal sharing of electrons between the atoms and the unsymmetrical shape of the molecule means that a water molecule has two poles - a positive charge on the hydrogen pole (side) and a negative charge on the oxygen pole (side). We say that the water molecule is electrically polar.
The reflection from plane mirror is shown in the diagram.
<h3><u>Explanation</u>:</h3>
The mirror is a plane surface which can reflect light. The diagram attached shows the schematic representation of reflection that occurs in a plane mirror.
The laws of reflection states that the incident ray, reflected ray and the normal at the point of incidence lies at the same plane. Here we can also see that all are lying on a same plane.
The second law states that angle of incidence is equal to angle of reflection. Here we can also see that the i =r. It is applicable here too.
Hi there!
I believe the answer to this is B. Elementary and High school students.
Hope this helps! ☺♥
Answer:
There are 12 nanoseconds in
.
Explanation:
We need to convert
to nanoseconds.
We know that,

Now using unitary method to solve it such that,

So, there are 12 nanoseconds in
.
