OVERALL MAYBE 7. SO 4 TO 14 AC SECONDS ? problem 5 the comet in the math lesson was 114 million KM away and at that distance each arc minute was 33,000 km 114,000,000 = 628 161 459 --- --- ---------- 33,000 x X = 143953.6676875 KM / ARC-MINUTE OR = 2399.227 KM PER ARC SECOND AT 4.199 AU SO 4 ARC-SECONDS = 9,596.911 KM FOR THE CENTRAL IMAGE [BRIGHTEST AREA] AND 14 ARC-SECONDS = 33,589.189 KM WITH TAIL I ESTIMATE TO BE 23 ARC SECONDS, OR 55,182.239 KM april 2 image [link to www.aerith.net] Quoting: rphunter For your calculations: 1 pixel in the photo = 2" (2 arcseconds) . Hi rphunter sorry, but your calculation is wrong. Please use this picture (edge filter and histogram adjustment to find the approximate borders of the comet): [link to p-m-a.org] And please use this formula to calculate the sizes: X = 2 *(b * (tan(alpha/2)) X = diameter in kilometers b = distance Earth-ISON in kilometers alpha = angular size in degrees 1" (1 arcsecond) = alpha/3600 degrees 1' (1 arcminute) = alpha/60 degrees (To calculate "tan(alpha)" you can use the Windows calculator in scientific mode) From the picture above: Innermost bright part = 1 px = 2" Coma = 26 px = 52" Tail + coma = 57 px = 114" Distance Earth-ISON = 4.199 AU = 628,161,459 kilometers ------------------------------------------------ Let's do it step by step for the innermost part: alpha = 1 px = 2" alpha = 2" = 2/3600° = 0.0005555° alpha/2 = 0.0002777° tan(alpha/2) = tan(0.0002777) = 0.00000484678 b = 628,161,459 km tan(alpha/2) = 0.00000484678 2 * (b * tan(alpha/2)) = 2 * (628,161,459 km * 0.00000484678) = 2 * 3044,5600 = 6089.12 km Innermost part = ~6090 km This is not the size of the nucleus - it's just the brightest part of the coma. The nucleus itself is beyond the resolution of the camera. Coma = ~158,400 km Coma + Tail = ~347,200 km Tail = ~188,800 km . The image scale listed for that image is incorrect. It's about 3 times smaller in scale than that: [link to nova.astrometry.net] .647" / pixel |

[link to www.jick.net] the gravitational attraction between the two protons is roughly a trillion trillion trillion times weaker than the electrostatic repulsion. The electrical force wins, hands down. However, in spite of its phenomenal puniness, gravity can overcome all other forces if enough mass gets piled up in one place. as i said, mass per mass, the electromagnetic forces far exceed the forces of gravity. sure you can build up quintillions of times the matter to get some strong gravity, but that's not a fair comparison. even then, the electromagnetic forces hold their own. rhombus will set you free... — some try to tell me thoughts they cannot defend. just what you want to be, you will be in the end! — if you can't face the truth it's probably raping you from behind. |

Hydra User ID: 37811551 Germany 04/11/2013 08:31 AM Report Abusive Post Report Copyright Violation | Still waiting for the proof of your claim, that "gravity is a piss-poor force compared to the electromagnetic forces" in space. Quoting: Hydra [link to www.jick.net] the gravitational attraction between the two protons is roughly a trillion trillion trillion times weaker than the electrostatic repulsion. The electrical force wins, hands down. However, in spite of its phenomenal puniness, gravity can overcome all other forces if enough mass gets piled up in one place. What has the link to do with your original claim? Your original claim talks about electromagnetic forces in space. Your link (and your italic quote) talks about electrostatic forces. Big difference - Trying to confuse the readers? as i said, mass per mass, the electromagnetic forces far exceed the forces of gravity. sure you can build up quintillions of times the matter to get some strong gravity, but that's not a fair comparison. even then, the electromagnetic forces hold their own. Quoting: genba Quoting right from the video - nice, when it's on YouTube, it must be true. Before you post such a video you should inform about interatomic bonds like ionic, covalent and van der Waals bonds. All these are closer to electrostatic forces than electromagnetic forces. To prove you video wrong: Drop a 70kg iron ball from a building to a concrete pavement. Will it bounce back or will the concrete brake? Or smash a wrecking ball agains a concrete wall. Empirical observation confirms, that it breaks the concrete and is not bounced back from electromagnetic forces. Or drop an iron ball into water. According to the video it shouldn't sink but also bounce back because of the electromagnetic forces. And best of all: If the video is right and the ground is electromagnetic you should get a magnet to hover above the pavement. If you can built such a device and it's working, you'll for sure get the Nobel Prize. But what has all this to do with your claim of immense electromagnetic forces in space. Atoms and molecules are quite rare in space. Next try - I'm still waiting for the proof of your claim, that "gravity is a piss-poor force compared to the electromagnetic forces" in space. . :ase26122019: Annular Solar Eclipse - December 26, 2019 - Kannur, Kerala, India |

Hydra User ID: 37811551 Germany 04/11/2013 09:17 AM Report Abusive Post Report Copyright Violation | There is a correction to my calculation of the comet ISON sizes some pages ago. [link to www.aerith.net] The value in the third line for 1 pixel = 2" is wrong. The value for the field (7' x 4') is also questionable - it gives 0.60"/px horizontal and 0.46"/px vertical. Most probably the values are from an earlier picture or it's a display detail with the original values kept. Nevertheless, the astrometric data of the picture gives a value of: 1 pixel = 0.647" (Thanks Astro) [link to nova.astrometry.net] Corrected calculation with: 1 pixel = 0.647" Innermost brightest part = 1 px = 0.647" Coma = 26 px = 16.8" Tail + coma = 57 px = 36.9" Distance Earth-ISON = 4.199 AU = 628,161,459 kilometers The correct values: Innermost part = ~1970 km This is not the size of the nucleus - it's just the brightest part of the coma. The nucleus itself is far beyond the resolution of the camera. Coma = ~51,200 km Coma + Tail = ~112,400 km Tail = ~61,200 km . :ase26122019: Annular Solar Eclipse - December 26, 2019 - Kannur, Kerala, India |
Anonymous Coward User ID: 3616254 United States 04/11/2013 12:08 PM Report Abusive Post Report Copyright Violation | With a distance from the Sun of 4.1 AU ISON is around the outer edge of the belt. At 3.3 AU it crosses into the bigger part of the belt, that is around 16 June. You forgot to mention, that it will be about 80-100 million kilometers above the asteroid belt. No way to disturb it. . you're assuming gravity is the only way it could influence anything. gravity is a piss-poor force compared to the electromagnetic forces. To an extremely high degree of accuracy we can predict the positions of all the objects in the solar system using just gravitational forces. While electromagnetic forces are stronger than gravitational forces the fact that most objects are electrically neutral means the electrical force is negligible. A strong electrical charge would require an additional term in the perturbation mechanics. Such a term has never been needed. Gravitational forces fall off as one over r squared. Electrical dipoles fall off as one over r cubed. Magnetic dipoles fall off as one over r to the fourth. The long range electrical and magnetic forces can be ignored. |
