There can be errors in the execution of the Law but there can be no errors in the execution of the Principle. The Principle operates in ideal conditions.

In Principle the right triangle is 90 degrees; in practice you may never construct a right triangle of 90 degrees. The Principle of Conservation of Matter-Energy does not allow for missing matter-energy; The Law of Conservation of Matter-Energy allows for missing matter-energy if the missing part can be said to reside in error.

Weber's law applies most directly to what concept?

Weber's law applies most directly to the concept of psychophysics, which is the study of the relationship between physical stimuli and the sensations and perceptions they produce. Weber's law specifies the just noticeable difference (JND) in a stimulus that is required for a person to perceive a difference.


Does temperature difference affect heat transfer rate?

Yes, temperature difference does affect heat transfer rate. The greater the temperature difference between two objects, the faster heat will transfer between them. This is described by Newton's Law of Cooling, where the rate of heat transfer is directly proportional to the temperature difference.


What is the relationship between the current flowing through a wire and the potential difference across it?

The relationship between the current flowing through a wire and the potential difference across it is described by Ohm's Law. Ohm's Law states that the current (I) flowing through a wire is directly proportional to the potential difference (V) across it, and inversely proportional to the resistance (R) of the wire. Mathematically, this relationship is represented as V I R.


What is the difference between inertia and Newton's first law?

Inertia is the tendency of an object to resist changes in its state of motion, whether at rest or in motion. Newton's first law states that an object will remain at rest or in uniform motion in a straight line unless acted upon by an external force. Inertia is the concept that underlies Newton's first law.


Newton's law of cooling applies to objects that are?

Newton's law of cooling applies to objects that are both heating and cooling. Newton's Law of Cooling states that the rate of change of the temperature of an object is proportional to the difference between its own temperature and the temperature of its surroundings.
