Answer:
As the object moves parallel to principle axis the image of the object will continuously moves away from the principal axis so the horizontal distance will increase
Explanation:
As the object is moving towards the lens then in that case first the image will form between the focus and double the distance of focus.
So here the image is diminished
now when the object is at large distance from from lens then its image will form at focus and it is of very small size
Now as the object comes closer to the lens till the object distance is 2F the image size will increase but smaller then object size
Now when object is between F and 2F then the image size will be more than object size and it will increase to infinite magnification
So overall we can say that as the object moves parallel to principle axis the image of the object will continuously moves away from the principal axis so the horizontal distance will increase
Answer:
t = 3.94 s
Explanation:
This can be modeled as a case of free fall motion. Because, the falcon is going down with acceleration, that is equal to acceleration due to gravity. To find the time taken by the falcon to intercept the pigeon, we will use second equation of motion for vertical direction:
where,
h = height = 76 m
vi = initial speed of falcon = 0 m/s
t = time required = ?
g = acceleration due to gravity = 9.81 m/s²
Therefore,
<u>t = 3.94 s</u>
The density of seawater plays a vital role in causing ocean currents and circulating heat because of the fact that dense water sinks below less dense. long story short, seawater is the problem because its denser than pure water.
Answer:
The Big Bang was the moment that the universe began, that as a tiny dense and the exploded!!!!!!! BOMBBBBBBBBBBBBBBB
Explanation:
Answer:
All 88 constellations are based on figures that originated in Greek and Middle Eastern mythology. (<em>Correct</em>)
The α star in a constellation is usually brighter than the β star. (<em>Correct</em>)
All stars are part of some constellation. (<em>Correct</em>)
The modern constellations have English names rather than Latin like the ancient ones. (<em>Correct</em>)
Explanation:
Constellations were grouped by different civilizations as mean to be oriented when they were making observations of the sky (they could see as maps of certain regions). Each constellation is an arrangement of several stars in a specific figure (animals, mythological characters and objects), things that were important for that civilization.
The letter 
is given to the brightest star in a constellation while the other letters of the Greek alphabet are assigned to the other stars that belong to that specific constellation according to their brightness. For example in the Orion constellation the brightest star is Betelgeuse so it is classified with an ; 
to Rigel, the second in brightness and so on. That classification system was established by the astronomer Johann Bayer in 1603.
The modern constellations have English names, for example the constellations of Telescopium, Fornax, Sculptor, Chamaeleon, among others.
As constellations represent maps of different regions in the sky, any star will be related with them. For that reason is correct to say that all stars are part of some constellation.
