Question:
Choose the correct answer:
1.The electronegativity of the 3 elements (Pauling scale) are: O: 3.5; C: 2.5; N: 3.0. Which molecule will have the greater permanent dipole moment:
A. NO
B. CO
2. In a constant electric field, a molecule with a permanent dipole moment:
A. Permanent dipoles orient themselves according to the field without any field-induced changes in the magnitude of the dipole moment
B. Permanent dipoles orient themselves according to the field and the induced dipole moment is generated (change of the permanent moment value)
3. In an alternating electric field with a very high frequency of field sense changes (very rapidly changing):
A. An induced dipole moment is created and the permanent dipole moment still has time to orientate with the field line
B. An induced dipole moment is created, but the permanent dipole moment does not have time to orientate to the field line
4. How much the applied external electric field is weakened in the dielectric as a result of the orientation of permanent dipoles and the formation of induced dipole moments, tells us:
A. Electric conductivity
B. Electrical permeability of the medium
