- B.
It's the breaking of a shape by terms in its defining equations of motion that do not respect the symmetry.
- C.
It's the breaking of a symmetry of a theory by terms in its defining equations of motion that do not respect the theory.
- D.
It's the breaking of a symmetry of a calculations by terms in its defining equations of motion that do not respect the symmetry.
Correct Answer
A. It's the breaking of a symmetry of a theory by terms in its defining equations of motion that do not respect the symmetry.Explanation
Explicit symmetry breaking refers to the breaking of a symmetry in a theory. This occurs when the defining equations of motion in the theory include terms that do not respect the symmetry. In other words, the equations of motion introduce terms that violate the symmetry that the theory originally possessed. This breaking of symmetry can have significant implications for the behavior and predictions of the theory.Rate this question:

What's a symmetry group?
- A.
It's the group of all transformation under which the object is variant.
- B.
It's the group of all transformation under which the object is invariant with composition as the group operation
- C.
It's the group of all transformation under which the object is variant with composition as the group operation
- D.
It's all transformations under which the object is invariant with composition as the group operation
Correct Answer
B. It's the group of all transformation under which the object is invariant with composition as the group operationExplanation
The correct answer is "It's the group of all transformation under which the object is invariant with composition as the group operation". This means that a symmetry group consists of all the transformations that can be applied to an object without changing its overall shape or structure, and the composition of these transformations is the group operation. In other words, the symmetry group is the set of all transformations that preserve the object's symmetry.Rate this question:

Correct Answer
D. It's a theorem expressing a duality between the process of restricting and inducing.Explanation
Frobenius reciprocity is a theorem that establishes a duality between the process of restricting and inducing. It states that when a representation of a subgroup is restricted to a smaller subgroup, and then induced back to the original group, it is isomorphic to the original representation. This theorem allows for the study of representations of a group through the study of representations of its subgroups, providing a useful tool in representation theory.Rate this question:

What's the Stark effect?
- A.
It's the shifting and splitting of spectral lines of atoms and molecules due to presence of an external electric field.
- B.
It's the splitting of spectral lines of atoms and molecules due to presence of an external electric field.
- C.
It's the shifting of spectral lines of atoms and molecules due to presence of an external electric field.
- D.
It's the shifting and splitting of lines of molecules due to presence of an external electric field.
Correct Answer
A. It's the shifting and splitting of spectral lines of atoms and molecules due to presence of an external electric field.Explanation
The Stark effect refers to the shifting and splitting of spectral lines of atoms and molecules when an external electric field is applied. This phenomenon occurs due to the interaction between the electric field and the charged particles in the atoms or molecules. The electric field causes the energy levels of the particles to shift, resulting in the spectral lines being shifted or split. This effect is important in the study of atomic and molecular spectroscopy and provides valuable information about the structure and behavior of these particles in the presence of electric fields.Rate this question:

- D.
It's from the function h:G----H
Correct Answer
C. It's from the function h:G----H such that for all U and V in G it holds that H(u*v)=h(u).h(v)Explanation
The correct answer is "It's from the function h:G----H such that for all U and V in G it holds that H(u*v)=h(u).h(v)". This answer accurately describes group homomorphism by stating that the function h maps elements from group G to group H in a way that preserves the group operation. It specifies that for any elements U and V in G, the product of their images under h in H is equal to the image of their product under h.Rate this question:
