Yes. As far as I am aware, no exceptions are known.
The Heisenberg Uncertainty Principle states that it is impossible to know both the position and momentum of an electron within at atom's electron cloud. As soon as you determine one property, the other is rendered invalid by your means of measurement.
The Heisenberg Uncertainty principle is part of the foundations of Quantum Mechanics and is still considered to be valid today. It means there is a fundamental fuzziness or uncertainty about the world at the quantum level. Even in principle we cannot know to high accuracy say both the position and the momentum of a small particle like the electron.
No, it is not true; the law remain valid.
In principle yes, but its effects are completely negligible above the quantum level. The Uncertainty Principle is valid at all levels - but it is only noticeable at the quantum level. For example it is difficult to know both the momentum and location of an electron because the uncertainty of these values is close in magnitude to the real values. x=1 +/- 1 whereas both the momentum and location of the planet Jupiter are known to a very large degree of accuracy because the value of its location is much great than the uncertainty in its location. x=1.5 x 1059 +/- 1 the uncertainty is alway of the same magnitude, you see. (no units to these values as I'm too lazy to look them up or do any sort of conversions)
The Principle of Uniform Processes states that the same processes acting on the earth today have acted on the earth throughout its history. It states that laws of physics and chemistry have not changed through time. Therefore, the processes that work today on the earth has always been acting, although not necessarily at the same rates that they do now.
No, this does not violate the conservation of momentum principle. As the ball is thrown up, its vertical velocity decreases, causing a decrease in momentum in that direction. However, the overall momentum of the ball (including horizontal and vertical components) remains constant in the absence of external forces. When the ball reaches its highest point and falls back down, its vertical velocity increases again, conserving the total momentum of the system.
The Law of Conservation of Energy is valid in all isolated systems where there is no external energy being added or lost. It is a fundamental principle in physics that states the total energy within a closed system remains constant over time.
In the case of an elastic collision, you can write two equations, which can help you solve certain practical problems. 1) Conservation of momentum. The total momentum before the collision is the same as the total momentum after the collision. 2) Conservation of energy. The total mechanical energy before and after the collision are the same. Note: The first equation is also valid for inelastic collisions; the second one is not.
It is valid

it is not valid for hydrogen
why caveat emptor principal is not fully valid in the present scenario
The law of mass conservation is generally valid.
when the principle die the irrevocable power of attorney is valid or invalid

In my view reliable test is always valid.
