የ12ኛ ክፍል ብሔራዊ ፈተና መቼ ይሰጣል?

የ2016 ዓ.ም የ12ኛ ክፍል ብሔራዊ መልቀቂያ ፈተና መቼ እንደሚሰጥ በርካቶች ጥያቄ አድርሰውናል።

የ12ኛ ክፍል ብሔራዊ ፈተና በሰኔ ወር እንደሚሰጥ የትምህርት ምዘናና ፈተናዎች አገልግሎት መግለፁ ይታወቃል።

በዚህ ዓመት የሚሰጠውን የ12ኛ ክፍል ሀገር አቀፍ ፈተና ለመውሰድ ከ670 ሺህ በላይ ተማሪዎች ምዝገባ እንዳደረጉ መገለፁም ይታወሳል፡፡

ለሦስተኛ ጊዜ በዩኒቨርሲቲዎች ውስጥ የሚሰጠው ብሔራዊ ፈተናው፤ ዘንድሮ ለተፈጥሮ ሳይንስ እና ለማኅበራዊ ሳይንስ የትምህርት መስኮች ለእያንዳንዳቸው በስድስት የትምህርት አይነቶች እንዲሰጥ ትምህርት ሚኒስቴር መወሰኑ አይዘነጋም፡፡

♻️ Important Scientific Laws and Theories ♻️
==============================

🔹 Ohm's Law - It states that the current passing through a conductor between two points is directly proportional to the potential difference across the two points provided the physical state and temperature etc. of the conductor does not change.

🔹 Pauli exclusion principle - It explains that no two electrons in the same atom or molecule can have the same set of quantum numbers.

🔹 Raman effect - It is the change in wavelength that occurs when light is scattered by the atoms or molecules in a transparent medium.

🔹 Tyndall effect - The scattering of light by very small particles suspended in a gas or liquid.

🔹 Boyles's Law - It states that temperature remaining constant, volume of a given mass of a gas varies inversely with the pressure of the gas. Thus,
PV = K (constant), where, P = Pressure and V = Volume.

🔹 Charles's Law - It states that pressure remaining constant, the volume of a given mass of gas increases or decreases by 1/273 part of its volume at 0 degree celsius for each degree celsius rise or fall of its temperature.

🔹 Coulomb's Law - It states that force of attraction or repulsion between two charges is proportional to the amount of charge on both charges and inversely proportional to the square of the distance between them.

🔹 Heisenberg principle (uncertainty principle) - It is impossible to determine with accuracy both the position and the momentum of a particle such as electron simultaneously.

🔹 Archimede's principle - It states that a body when wholly or partially immersed in a liquid, experiences an upward thrust which is equal to the weight of the liquid displaced by it. Thus, the body appears to lose a part of its weight. This loss in weight is equal to the weight of the liquid displaced by the body.

🔹 Aufbau principle - It states that in an unexcited atom, electrons reside in the lowest energy orbitals available to them.

🔹 Avogadro's Law - It states that equal volumes of all gases under similar conditions of temperature and pressure contain equal number of molecules.

🔹 Brownian motion - It is a zigzag, irregular motion exhibited by small solid particles when suspended in a liquid or gas due to irregular bombardment by the liquid or gas molecules.

🔹 Bernoulli's principle - It states that as the speed of a moving fluid, liquid or gas, increases, the pressure within the fluid decreases. The aerodynamic lift on the wing of an aeroplane is also explained in part by this principle.

🔹 Gay-Lussac’s Law of combining volumes - Gases react together in volumes which bear simple whole number ratios to one another and also to the volumes of the products, if gaseous — all the volumes being measured under similar conditions of temperature and pressure.

🔹 Graham’s Law of Diffusion - It states that the rates of diffusion of gases are inversely proportional to the square roots of their densities under similar conditions of temperature and pressure.

🔹 Kepler's Law - Each planet revolves round the Sun in an elliptical orbit with the Sun at one focus. The straight line joining the Sun and the planet sweeps out equal areas in equal intervals. The squares of the orbital periods of planets are proportional to the cubes of their mean distance from the Sun.

🔹 Law of Floatation - For a body to float, the following conditions must be fulfilled: The weight of the body should be equal to the weight of the water displaced and the centre of gravity of the body and that of the liquid displaced should be in the same straight line.

🔹 Law of conservation of energy - It states that energy can neither be created nor destroyed but it can be transformed from one form to another. Since energy cannot be created or destroyed, the amount of energy present in the universe is always remain constant.
