Answer:
so this is nearly red colour light
Explanation:
As we know that the interference of light from reflected light then the path difference is given as
now we know that for constructive interference of light the path difference is given as
so we will have
so we will have
so this is nearly red colour light
The electrical force between these two charges remains the
same. In coulomb’s law, it states that the magnitude of two charges (product of
two charges) is inversely proportional to the square of the distance. Since both
the magnitude and the distance are halved, therefore, the change in both quantities
will have no effect in the value of electrical force.
Answer:
3000 newton force is required
Explanation:
F = ma
F= 1000 kgs x 3 m/s^ 2
F=3000(kgs x m/s^2)
F=3000 newton
Ionic bond: it is also called "electrovalent bond". It is "a type of chemical bond that can often form between metal and non-metal ions through electrostatic attraction";
Covalent bond is a form of chemical bonding, "characterized by the sharing of pairs of electrons between atoms, or between atoms and other covalent bonds";
Metallic bond: "the chemical bond, which is characteristic of metals, in which mobile valence electrons are shared among atoms in a usually stable crystalline".
