How does rotatory motion differ from circular motion? |
|
Answer» In the body itself whereas in circular motion, the AXIS of revolution passes through a point outside the body. Thus the motion of EARTH around the sun is the circular motion whereas the motion of earth about its own axis is the ROTATIONAL motion.Explanation:Hope this answer is HELPFUL for you.Thank you.PLEASE MARK ME BRAINLIEST |

Bell jar experiment fully in detail |
|
Answer» The experiment is done by PLACING an electrical bell in the bell jar. As the air is pumped out of the sealed bell jar, the sound from the bell jar fades. ... This demonstrates that the sound WAVE cannot TRAVEL through vacuum. That is, a sound wave needs a MATERIAL medium for its PROPAGATION. |

Calculate the induced dipole moment per unit volume (density of polarization) of He gas if placed in a field of 6 x 105 V/m. the atomic polarizability of He atom is 2.6 x 1025/m3 . Also calculate the separation of positive and negative charges in each atom. |
|
Answer» Total Polarization In the presence of ELECTRONIC, ionic and dipolar polarization mechanisms, the average induced dipole moment per molecule pav will be the sum of all the contributions in TERMS of the local field (effective field) acting on each individual molecule,Clausius Mossotti Equation | Static relative Permittivity | Polarization of Dielectric Materials equation 1where αe, αi and αd are the electronic, ionic and dipolar (orientational) polarizabilities. Eloc is the local field, the effective field, at the site of an individual molecule that causes the induced polarization. Each effect ADDS linearly to the net dipole moment per molecule which is a fact verified by experiments. Interfacial polarization cannot be simply added to the above as αif Eloc because it occurs at interfaces and cannot be put into an average polarization per molecule in the bulk.Further, the fields are not well defined at the interfaces. In the simplest case (valid for GASES), we can take the local field to be the same field (average field in the sample). This means that Eloc = E and therefore polarization Clausius Mossotti Equation | Static relative Permittivity | Polarization of Dielectric Materials equation 2 Since P = Npav, where N is the number of atoms or molecules per unit volume,Clausius Mossotti Equation | Static relative Permittivity | Polarization of Dielectric Materials equation 3where α is the polarizability of the molecule. In solids we have to consider the actual effective field acting on a molecule. In the case of electronic and ionic polarization, the local field for cubic crystals and ISOTROPIC materials (such as liquids) can be shown to be given by the Lorentz fieldClausius Mossotti Equation | Static relative Permittivity | Polarization of Dielectric Materials equation 4 |

What is Analgous expansion of water |
|
Answer» The anomalous expansion of WATER is an abnormal property of water whereby it expands instead of contracting when the temperature goes from 4o C to 0O C, and it becomes less dense. ... The density becomes less and less as it freezes because molecules of water normally form open crystal structures when in SOLID form.Explanation:it can help you follow me |

How do we indicate uncertainties |
|
Answer» Uncertainties are almost always quoted to one significant digit (example: ±0.05 s). If the uncertainty starts with a one, some SCIENTISTS QUOTE the uncertainty to TWO significant digits (example: ±0.0012 kg). Always round the experimental measurement or result to the same DECIMAL place as the uncertainty.Explanation:I hope it is helpful plz marks me as brainlieast and give me thanks at all my answers and follow me |
