A wave can form in the electromagnetic field, or it might be static or slowly changing. Light generally refers to electromagnetic waves that follow the principles of optics Grande Prairie Snow Removal |

2023-05-04 17:41:48 | Maxwell\'s equations are a set of four partial differential equations that describe the behavior of electric and magnetic fields and their interaction with charges and currents, forming the foundation of classical electromagnetism. Is anyone interested to credit repair laredo?\r\n\r\n\r\n\r\n\r\n\r\n |

2019-12-18 06:28:15 | According to this solution, \"the cross-product yields 0 force for the two horizontal components,\" but is that right? The field is pointing into the page, which is orthogonal to the line of the induced current, thus there would be force on each horizontal component. This contributes nothing to the net force due to symmetry: the top and bottom horizontal portions of the induced current cancel one another out. |

Then, if E is much larger than the rest energy of the electron E0 = me c2 = 0.511 MeV, it is found that the final photon energy E′ is equal to E0/2. www.dc-harvest.com/ |

2019-10-22 23:07:47 | this is a bit misleading because you can easily use negative feedback to amplify signal if you have an op amp and two resistors, which is what I immediately thought of when they said negative feedback.\r\nGuess they were referring to the concept of negative feedback itself, not applications?? |

2019-10-22 04:40:35 | oh sorry guys, I found another way: The energy to remove 2 electrons(79.0)= remove 1st+remove 2nd. Since remove 1st is under help of second electron\'s repel force. Removing second is 2^2*13.6=54.4 remove 1st=79-54.4=24.6 |

2019-10-22 04:34:15 | since there are interaction between two electrons. we can solve in this way: STEP1： Remove two electrons(79eV) STEP2: pull one electron back(13.6*2^2=54.4eV) the result is also equals: ionize one electron. \\\\r\\\\nThe trick is, we can just calculate ionize energy of isolated electron, so we have to find a way isolate them. \\\\r\\\\nThe result is: 79-54.4=24.6 (we set remove is plus,pull back is minus) |
