Answer: kindly see Explanation
Explanation:
Atoms bond in other to achieve a stable valence electron shell. Through bonding, atoms with incomplete valency in the outer shell may accept, lose or share electrons with another atom in other to achieve a stable outer shell or configuration.
Ionic bonding:
Ionic or electrovalent bonding simply occurs when atoms accept or lose electrons in their outer shell in other to achieve stability. Elements that require 1 atom to achieve stability accepts from elements which requires losing 1 atom in other to achieve a stable outer shell.
Example is Sodium chloride (NaCl) sodium loses one atom, which chlorine accepts and both achieve a stable outer shell.
Covalent bonding simply refers to electron sharing between atoms. Instead of losing or accepting, the atoms bond by sharing electron to achieve stability. Such is the bonding between Hydrogen and Oxygen in the formation of H2O, oxygen requires two electrons to attain stability, each hydrogen atom requires one each to attain stability, through sharing oxygen attains two more electrons, one each from the hygrogen atoms and the oxygen atom also shares one electron with each hydrogen atom. Then all the atoms atoms stability.
Answer:
0.29D
Explanation:
Given that
F = G M m / r2
F = GM(6m) / (D-r)2
G Mm/r2 = GM(6m) / (D-r)2
1/r2 = 6 / (D-r)2
r = D / (Ö6 + 1)
r = 0.29 D

Answer:
Secondary voltage on second transformer is 200 volt.
Explanation:
It is given two transformer
Let us consider first transformer.
Number of turns in primary
Numb er of turns in secondary
Now consider second transformer
Number of turns in primary
Number of turns in secondary
Now it is given that same voltage of 50 volt is applied to primary of both the transformer.
For second transformer
So secondary voltage on second transformer is 200 volt
Answer:
A
Explanation:
The most important part about this is not only that objects pull on each other, but that two objects attract each other with a force that is proportional to the product of their masses and inversely proportional to the square of the distance between them. This is known as Newton's law of universal gravitation.
