WebIf they are false, correct them. (a) The total intensity of radiation emitted from a black body at absolute temperature T is directly proportional to the temperature. (b) As the temperature of a black body increases, the wavelength at which the maximum intensity is found decreases. (c) Photons of radio-frequency radiation are higher in energy ... WebAstronomers use an effect called parallax to measure distances to nearby stars. Parallax is the apparent displacement of an object because of a change in the observer's point of view. The video below describes how this effect can be observed in an everyday situation, as well as how it is seen and used for finding distances to stars. Stellar ...

WebThe most direct way to estimate the maximum distance at which a candle can be seen is to first determine how far one has to be situated from a candle such that it is comparable in brightness to a star of magnitude V = 0, such as Vega or Rigel. We find that this distance is 160 to 200 m. This can be double checked with a CCD imager. WebAt that time, Apollo 14 will be at a distance of 184,793 nautical miles away from the Earth and at a distance of 33,821 nautical miles away from the Moon. Fourteen's velocity relative to Earth will be 3,462 feet per second; fourteen's velocity relative to the Moon at that time will be 4,173 feet per second. Web20 jan. 2024 · Alnilam is a supergiant at around 2.000 light-years away from Earth, located in the middle of the belt. It has a magnitude of 1.70 and it is the 29 th-brightest star in the night sky and the fourth-brightest in Orion. Alnilam is around 375.000 times brighter than our sun while other estimates place it at around 832.000 times more brighter. bio 1 midterm exam e/bhcc/spring 2023
