Coulomb's law (C. de Coulomb)
The primary law for electrostatics is analogues to Newton's law of universal gravitation. This states that the force among two point charges is proportional to the algebraic product of their respective charges in addition to proportional to the inverse square of the distance among them; mathematically specking,
F = 1/(4 pi epsilon0) (q Q/r2) e,
where q and Q refer to the strengths of the two charges, r refer the distance among the two, and e refer to a unit vector directed from the test charge to the second.

The topic for the project is Newton's Law of Cooling, although you may choose a different title. The aim is to research how the temperature of a hot object is lost when it is kept
(i) X-rays are electromagnetic waves with wavelength lie among 0.1Å - 100Å. (ii) X-rays is invisible. (iii) They always go in a straight line with speed of light. (iv) X
Pauli exclusion principle (W. Pauli; 1925) No two similar fermions in a system, like electrons in an atom, can have an equal set of quantum numbers.
