Answer: Bohr's model (1913)
Niels Bohr improved Rutherford's model. Using mathematical ideas, he showed that electrons occupy shells or energy levels around the nucleus. The Dalton model has changed over time because of the discovery of subatomic particles.

Dalton's atomic theory proposed that all matter was composed of atoms, indivisible and indestructible building blocks. While all atoms of an element were identical, different elements had atoms of differing size and mass.
John Dalton
The idea that everything is made of atoms was pioneered by John Dalton (1766-1844) in a book he published in 1808. He is sometimes called the "father" of atomic theory, but judging from this photo on the right "grandfather" might be a better term.
Explanation:
A. The magnitude (in N) of the electric force that one particle exerts on the other is 8.60×10⁻⁸ N
B. The force is repulsive
<h3>A. How to determine the magnitude of the electric force</h3>
From the question given above, the following data were obtained:
- Charge 1 (q₁) = 7.03 nC = 7.03×10¯⁹ C
- Charge 2 (q₂) = 4.02 nC = 4.02×10¯⁹ C
- Electric constant (K) = 9×10⁹ Nm²/C²
- Distance apart (r) = 1.72 m
- Force (F) =?
The magnitude of the electric force can be obtained by using the Coulomb's law equation as shown below:
F = Kq₁q₂ / r²
F = (9×10⁹ × 7.03×10¯⁹ × 4.02×10¯⁹) / (1.72)²
F = 8.60×10⁻⁸ N
<h3>B. How to determine whether the force is attractive or repulsive</h3>
From the question given, we were told that:
- Charge 1 (q₁) = 7.03 nC
- Charge 2 (q₂) = 4.02 nC
Since both charge are positive, then the force attraction between them is repulsive as like charges repels and unlike charges attracts

If the thermal coefficient of resistivity for nichrome is 4.5 x 10-4 1/co, the temperature of the coil of the coil is 0.56 a.
<h3>What is
resistivity?</h3>
Resistivity is a central property of a material, and it shows how unequivocally the material opposes or transmits electric flow. A low resistivity is an obvious sign of a material which promptly permits electric flow. The resistivity increments implies that the conductivity of the material abatements. For metals or transmitters, it is said that they have a positive temperature co effective. The worth α is positive. Electrical resistivity is a property interesting to each material, which is fundamental to comprehend prior to making and planning electrical and electronic frameworks.
