[amp_mcq option1=”When the star momentarily moves vertically” option2=”When the angle at the star of the spherical triangle is 90\u00c2\u00b0” option3=”When the star” option4=”All the above” correct=”option1″]<\/p>\n
The correct answer is A. When the star momentarily moves vertically.<\/p>\n
A star is said to elongate when it momentarily moves vertically. This is because the star is actually a point of light, and when it moves vertically, it appears to elongate. This is similar to how a car’s headlights appear to elongate when they are moving towards you.<\/p>\n
Option B is incorrect because the angle at the star of the spherical triangle is not always 90\u00c2\u00b0. The angle at the star of the spherical triangle is the angle between the star and the horizon. This angle can be any value between 0\u00c2\u00b0 and 180\u00c2\u00b0.<\/p>\n
Option C is incorrect because the star does not always move vertically. The star can move in any direction, including horizontally.<\/p>\n
Option D is incorrect because only option A is correct.<\/p>\n","protected":false},"excerpt":{"rendered":"
