If the object was a regular shape (a cube for example) it would cast the same shadow from any angle. An irregular shape (such as a car) will cast different shadows dependent upon the source of the light.

What is the longest length a shadow cast of a 10 foot tall object?
In therory, infinitely long. In practice, the shadow will fade into dispersed light.
Thomas happened to notice that at 400 PM on his uncle's farm a fence post that was 5 feet tall cast a 3 foot shadow He also noticed that a nearby tree cast a 12 foot shadow How tall is the tree?
I think this question is about similar shapes. To answer this divide the height of the tree, 5ft, by the shadow cast by it, 3 ft. This will give you the scale factor. To then find the answer, times the scale factor by the shawdow cast by the nearby tree, and will find your answer in ft. Hope this helped.
Thomas happened to notice that 4 oclock pm on his uncles farm a fence post that was 5 ft tall cast a 2 foot shadow he also noticed that a nearby tree cast a 10 foot shadow how tall is the tree?
25 feet tall This is in effect asking about similar triangles, the bases of which are the shadows and the (perpendicular) heights are the heights of the objects. Therefore, using the ratio of the two triangles (calculated from the "shadow" sides) the height of the tree can be determined. The ratio of the shadows of the post to tree is: 2ft : 10ft = 1:5 So the height of the tree is five times the height of the post. Thus: Height_of_tree = 5 x 5ft = 25 ft
When the shadow cast by a 1.2 m fence post was 1.8mthe shadow cast by a pine tree was 27.6m and by an oak tree was 45m.How tall was each tree?
There are similar triangles with the shadows as one side, the objects as another and the sun's rays as the third. The ratio of height to shadow is 1.2m : 1.8m = 1.2 : 1.8 = 2 : 3 Therefore to convert shadow length to height divide by 3 and multiply by 2, which is the same as multiplying by 2/3 → height pine = 2/3 × 27.6 m = 18.4 m → height oak = 2/3 × 45 m = 30 m
The ratio of yes votes to no votes in an election was 5 to 6 How many yes votes were cast if there were a total of 6281 votes cast?
The ratio of yes votes to no votes in an election was to . How many yes votes were cast if there were a total of votes cast?
What are the two types of shadows?
Cast and form shadows: -Cast shadows are just typical shadows that are created when light is blocked by an object. -Form shadows are the shadows that are on the object and away from the light source. Usually, in painting, cast shadows are used to give an object a more realistic and 3D look to them.

Can you see dark shapes on the moon?
NO, because there is no sun to cast shadows
If the earth was a flat what shapes could its shadow be?
If you imagine the shadows a CD can cast you'll get the idea.
How do we have shadows?
Shadows are the absence or reduction of light resulting from an object being in between the light source and the surface that the shadow is cast upon.
Why do shadows get smaller and bigger?
The size of a shadow has everything to do with placement of the light source, the object, and the background on which the shadow is cast. In general, if the light source is close to the object and the background is further away then the shadow is larger than the object. The opposite is true if the light source is further away. Another part of the equation has to do with angles. This is what we commonly observe happining to shadows at different times of the day; long shadows in the morning and evening and smaller shadows around the middle of the day.
Do shadows vary in size?
Yes, shadows can vary in size depending on the size and position of the light source, the distance between the object and the surface on which the shadow is cast, and the angle at which the light hits the object.
Is that possible to form two shadows of the same object?
Yes, it is possible for an object to cast several shadows. One example, is that of a footballer on a floodlit pitch. If he is in the central region of the field, you will usually see four shadows: one from each of the corner floodlights.
Why shadows exist?
A shadow is cast when sunlight is blocked by a solid object - a person, a post, etc.
How do shadows change through the day?
Shadows change when the sun moves in the sky because it hits objects from different directions, which causes them to cast a different shadow.
What feature on the moon casts dark shadows?
Any large object, such as a rock or a mountain will cast a shadow on the moon.
How does light interact with objects to cast shadows?
---------------------------------------------- The object blocks the light from whatever is behind it, therefore leaving a shadow. ----------------------------------------------
