yes
Shadows are places where the light cant get to, so depending on where the source of light is, the power or brightness of it and the size of the object, the shadow will change.
when the distance between the light source and the object changes
The position of the sun through out the day? The Earth's rotation changes the angle of the sun as the day passes, so the shadows change based on the position of the sun in the sky. If the sun is up high (around noon), the shadows will be short or not appear to exist (they are under or nearly under the objects). As it gets later in the day, the shadows get longer.
Not at all. The focal length is determined by the curvature of the surfaces.
As the earth rotates the angle if the sunlight changes which affects shadows.
Shadows change length during the day because as the earth rotates on its axis, the angle between the sun and any given point on the earth changes.
Depending on which angle the sun is in relation to your body your shadows length can change.
the shadows change as the earth rotates on its axis. the sun stays still so the shadows change.
Less quickly becaus it takes longer to rotate on its axis therefore one mercury day equals 59 earth days
Shadows lengths are less in summer than winter.
the lengths and direction of shadows change during the day because of some factors these are: 1) position of the earth facing the sun 2) time of the day 3) power of suns rays 4) place object is in 5) what object is around
Chicken nuggets
Shadows depend on the location of the light source.If, for example, the sun is your light source it will change the size and shape of shadows as it crosses the sky during the day.

Exactly the same as the change in the sun's position from noon to sunset affects them ... they stay exactly opposite the direction of the sun, but they get longer.
Shadows appear tallest in the morning because the sun is low on the horizon, casting longer shadows due to the angle of sunlight. As the day progresses, the sun rises higher, reducing the length of shadows.
