A tower casts a shadow 48 m long Tom is 2 meters tall and casts a shadow 8 meters long while standing in the tower's shadow How tall is the tower?
As the question is stated, Tom is standing IN THE TOWER'S SHADOW. If so, then Tom can't cast a shadow of his own, because he is not illuminated. Let's assume the question means to imply that Tom's shadow is measured AT THE SAME TIME that the shadow of the tower is measured, and kind of NEAR the tower, so that the sun casts both shadows from the same place in the sky. If this is a valid assumption, then the tower is 12 meters tall.
At a certain time of the day a tree 15m tall casts a shadow of 12m while a second tree casts a shadow of 20m how tall is the second tree?
25 meters because 25/20 = 15/12 which is the tangent ratio.
How many ways can 3 people stand in a line?
SixIf only the order is interesting (not the direction that they are oriented) then In the first place there can be any of the three, in the second place there can be either of the two left and then the last place is a given so: 3 * 2 * 1 = 6Six different orders for three people standing in a line.If their direction is also interesting to take into account (e.g. the middle person facing north while the others face east) then you have to know how many different directions and if standing on their heads counts as different etc.

How high is a tree that's casts a ft shadow at the same time a ft pole casts a shadow which is ft long?
To determine the height of the tree based on the shadow length, we can use the concept of similar triangles. If the tree casts a shadow of 1 foot while a 1-foot pole also casts a shadow of 1 foot, then the height of the tree is the same as the height of the pole. Thus, the tree is also 1 foot tall.
Does eclipse mean shadow?
An eclipse involves the blocking of light, typically from a celestial body, which creates a shadow. In a solar eclipse, the Moon casts a shadow on the Earth, while in a lunar eclipse, the Earth casts a shadow on the Moon. So, while "eclipse" itself doesn't mean "shadow," it is closely related to the phenomenon of shadows being cast during these events.
At a certain time of the day a tree 15m tall casts a shadow of 12m while a second tree casts a shadow of 20m how tall is the second tree?
25 meters because 25/20 = 15/12 which is the tangent ratio.
How tall is the pole if the pole casts a 24-foot shadow and a 3 and one half foot tall boy casts a 6-foot shadow while standing beside the pole?
Answer is 14 feet
At a certain time of the day a tree 15 m tall casts a shadow of 12 m while a second tree casts a shadow of 20 m How tall is the second tree?
By Similar Triangles. #1 is 15/12 #2 is x /20 Equating 15/12 = x/20 Algebraic rearrangement x = 15 x 20 / 12 x = 300 /12 x = 25 m.
Does the shadow casts on the moon cover totally the entire lunar surface?
During a full lunar eclipse, the visible half of the moon's surface is in the Earth's shadow while the rest does not receive sunlight because it is facing away from the Sun. Lunar eclipses occur during full moon phases.
A tree is standing next to a 40 foot high building the tree has an 18 foot shadow while the building has a 16 foot shadow how tall is the tree rounded to the nearest foot?
(18/16)x40=45
How does the size of the source affect the shadow of the object?
A bigger source will cast a fuzzier, less distinct shadow. A single point source, infinitely small, will on the other hand cast a perfectly defined shadow with an abrupt edge. The shadow is likely to be a good image of the object that casts it. But imagine standing in the shadow of an object shading you from a larger light source, like the moon. As you move your head, sometimes the moon's disc will only partially be obscured, and sometimes completely. The area of the shadow where the light is only partly blocked is the penumbra. A limited region of the shadow is shaded entirely from the light source: this is the umbra. The specific effect of enlarging a light source is to make the penumbra bigger and the umbra smaller. More areas will receive less than 100% of the light, but a smaller area will be 100% shadow - hence the blurring effect. Light and shadow are more evenly distributed. Overall, the area in some degree of shadow will increase. Try observing the shadow of your finger under artificial lighting at home: the dark umbra should be visible, and the grey penumbra where the shadow fades continously away to nothing. The blurring will also be exacerbated by moving your finger away from the surface onto which its shadow falls. Note that it is the angular size of the source that really matters. The sun is huge, but since it is so distant its angular diameter is only half a degree, so it casts fairly sharp shadows.
The presence of white blood cell casts in the urine is indicative of pyelonephritis and red blood cell casts indicative of glomerulonephritis?
White blood cell casts in the urine are typically associated with acute interstitial nephritis, while red blood cell casts are more commonly seen in acute glomerulonephritis. Pyelonephritis is usually characterized by the presence of white blood cells in the urine without casts.
Does military use waterproof casts?
Yes, the military does use waterproof casts for personnel who sustain injuries while in the field. These casts are designed to be durable and resistant to moisture, allowing soldiers to continue with their duties and maintain hygiene. Waterproof casts are particularly beneficial in environments where exposure to water is common, such as during training exercises or deployments.
Why can some areas on earth see the solar eclipe and not others?
A solar eclipse occurs when the moon is between the sun and the earth, and casts a shadow on the earth. The moon is small compared to the earth and the sun, so the shadow does not cover all of the earth.
