What does rule of thumb means?
"Rule of Thumb" means a rule or principle that provides guidance to appropriate behavior.
What is the rule of thumb stating that if there are two explanations for a phenomenon?

What is the octic rule?
The octet rule is a simple chemical rule of thumb that states that atoms tend to combine in such a way that they each have eight...
What is the origin of 'rule of thumb'?
Rule of thumb comes from the days before standardised measuring units. The thumb is the most useful digit for measuring as it is similar to the distance that became "The Inch" (my thumb is about 2.5") It should be noted that because it is an arbitrary figure, that is my thumb is not the same size as your thumb, my hand made thingummy will not be the same size as your hand made thingummy but the two should be in proportion. the average value for Rule of thumb will vary from race to race as an aside the biblical measurement "The cubit" is the distance from the elbow to the tip of the longest finger. which will again vary from race to race. ----- also the earliest known written occurrence of the expression was in 1692 when it already meant some method or procedure based on practical experience & without any formal basis my guess is the expression referred originally to the natural measuring rule for gauging distance from any seen object which calls for holding a thumb out at arms length against the distant object & then multiplying by 10 the horizontal distance the thumb appears to jump when viewed from alternately blinking eyes & as suggested above there are a variety of almost as commonly applied measuring rules involving the thumb which perhaps compete with this rule or perhaps all together support it both in its figurative sense as a law or principle & in its earlier literal sense as a physical ruler or measuring device
What is one geometry rule that the Greeks discovered do we still use today?
It is Pythagoras' theorem that is applicable to any right angle triangle.
What is the right hand thumb rule used for in relation to magnetic fields?
The right-hand thumb rule is used to determine the direction of magnetic field lines around a current-carrying conductor. By pointing your right thumb in the direction of the current flow, your fingers curl in the direction of the magnetic field lines.
When using the left hand rule for generator the thumb point in what dierction?
There is no left handed rule. The correct term is right handed rule. Using the right handed rule, your thumb is pointing in the direction of current flow, and your fingers are pointing in the direction of magnetic flux flow.
What is the right hand rule for determining the direction of a magnetic field when a current is flowing out of the page?
The right-hand rule states that if you point your right thumb in the direction of the current flow, your fingers will curl in the direction of the magnetic field.
What is the correct representation of the right-hand rule for a current flowing to the right?
The correct representation of the right-hand rule for a current flowing to the right is to point your right thumb in the direction of the current, and your curled fingers will show the direction of the magnetic field around the current.
How the hand right rule work?
The right-hand rule is used in physics to determine the direction of a magnetic field, current, or force in a moving conductor. To use the right-hand rule, point your right thumb in the direction of the current or movement, your fingers curled in the direction of the magnetic field, then your palm would face the direction of the force. The right-hand rule helps establish the relationship between these three factors in electromagnetism.
How to use the right hand rule for torque to determine the direction of the rotational force?
To use the right hand rule for torque, point your right thumb in the direction of the rotational force and curl your fingers in the direction of the rotation. Your fingers will then point in the direction of the torque.
What is Maxwell right hand rule?
Ampere's right hand thumb rule states that if you hold the current carrying wire in your right hand so that your thumb points in the direction of the current, then the direction in which your fingers encircle the wire give you the direction of the magnetic lines of force around the wire .On reversing the direction of current in thewire , the direction of the magnetic lines of force is also reversed.
How can the right hand rule be used to determine the direction of the magnetic field?
The right hand rule can be used to determine the direction of the magnetic field by pointing the thumb of your right hand in the direction of the current flow and curling your fingers. The direction in which your fingers curl represents the direction of the magnetic field.
What is the right hand rule for cross products and how is it used to determine the direction of the resulting vector?
The right-hand rule for cross products is a way to determine the direction of the resulting vector when two vectors are multiplied. To use the right-hand rule, align your right hand's fingers in the direction of the first vector, then curl them towards the second vector. Your thumb will point in the direction of the resulting vector.
How rigt hand thumb rule is used in determining the direction of magnetic field around a conductor carrying current?
Curl the fingers of your right hand into the palm and extend the thumb. The thumb indicates the direction of the current, and the direction of the fingers indicates the direction of the magnetic field.
What is the right-hand rule for angular displacement?
The right-hand rule for angular displacement states that if you align your fingers in the direction of rotation, your thumb points in the direction of the angular displacement vector. This rule helps determine the direction of rotation or angular displacement in a given scenario.
How to apply the right hand rule in physics?
To apply the right hand rule in physics, align your right hand with the direction of the current or magnetic field. Your thumb points in the direction of the current, while your fingers curl in the direction of the magnetic field or force. This rule helps determine the direction of forces or magnetic fields in various physics problems.
