Answer:
Therefore the magnitude of required electric force is 292.864×10⁻⁵ N.
Explanation:
The number of proton of iron is 26.
C is the charge of each proton.
Total charge of 26 proton is =(26×1.6×10⁻¹⁹) C
=41.6×10⁻¹⁹ C
The charge of innermost electron is = -
C
Coulomb's Law:
The attraction or repulsion force of two charges is
- directly proportional to the product of the charges.
- inversely proportion to the square of distance
Let
be two positive charge and the distance between the charges be r
Then F∝
and 
Therefore,

Here
= -
C and
=41.6×10⁻¹⁹ C
r = 1.5× 10⁻¹² m
K= 9.9× 10⁹C²N⁻¹m⁻²
Therefore
N
= -292.864×10⁻⁵ N
The mins sign shows the direction of the force.
Magnitude of electric force is only the numerical value of the force.
Therefore the magnitude of required electric force is 292.864×10⁻⁵ N.
-- transport of energy
-- wavelengths equal to their speed divided by their frequency
-- frequencies equal to their speed divided by their wavelength
-- periods equal to the reciprocal of their frequency
-- speeds that are determined by the characteristics of the medium
Plate tectonicss a property of the behavior of systems, plates, that are far from fundamental, like particles. So any statement about them is a theory.
A. elastic motion because that's the answer
Answer: 8Ω
Explanation:
Since there are two resistors of 4Ω
connected in series, the total resistance (Rtotal) of the circuit is the sum of each resistance.
i.e Rtotal = R1 + R2
R1 = 4Ω
R2 = 4Ω
Rtotal = ?
Rtotal = 4Ω + 4Ω
Rtotal = 8Ω
Thus, the total resistance of the circuit is 8Ω
