The answer is Newton's 3rd Law. The reason why is because a force is a push or a pull that acts upon an object as a results of its interaction with another object. ... These two forces are called action and reaction forces and are the subject ofNewton's third law of motion. Formally stated, Newton's third law is: For every action, there is an equal and opposite reaction.
Current always returns to the negative terminal.
<u>Explanation</u>:
Current flows from a positive to a negative terminal. It is due to the flow of negative electrons to positive side. The current flows from a high potential to a low potential. There is high concentration of electrons at the positive terminal and low concentration at the negative terminal. When the circuit is complete the electrons move from a high concentration to low concentration i.e; from positive terminal to negative terminal.
Coulomb's law:
F = k×q₁×q₂/r² where k ≈ 9.00×10⁹NC⁻²m²
Given values:
q₁ = +1.0C
q₂ = -1.0C
F = 650N
Substitute the terms in Coulomb's law with our given values. We will have to use the absolute value of q₂ to so the algebra works out. Solve for r:
650 = 9.00×10⁹×1.0×1.0/r²
r = 3721m
Taking significant figures into account:
<h3>r = 3700m</h3>
Answer: Electric field is given as
E = V/d
E = 220 v / 0.0056m
E = 39285.71 v/m
Or
E = 39285.71 N/C
Explanation: Therefore electric field is 39285.71 V/m
Ionic compounds are always salts forming between a metal and a non-metal
Examples include, but are not limited to
NaCl
BaF2
Cs2O
Sometimes an ionic compound can be composed of a metal + a polyatomic ion
Examples of polyatomic ions include
Phosphate PO4 3-
Chlorate ClO3-
Some ionic compounds with these polyatomic ions include
CsClO3
Ba3(PO4)2
Hope this helps. I can’t do much good if I can’t see the options.
