How would solar eclipses be different if the Moon were twice as far from EarthWhy?
If the Moon were at twice its orbital distance, there would be no total solar eclipses, only annular ones. This is because the umbra, the complete shadow of the Moon, would not reach to the Earth. I would have to run the numbers to be certain, but I suspect that there would be no total lunar eclipses, either, for the same reason. However, you would probably be able to see the shadow of the Earth passing across the face of the Moon!
Is hectare the unit of perimeter?
No, it is a unit of area (square units) equal to 10,000 square meters. There is no "unit of perimeter" (it is the linear distance around the outside of a shape, analogous to the circumference of a circle). For rectangles, P = 2L + 2W (twice the length plus twice the width). For squares, P = 4S (4 x side length).
If the linear scale of a map is twice another is its aerial representation is four times larger?
If the linear scale of a map is twice that of another map, the aerial representation will be four times larger due to the square relationship between linear scale and aerial representation. This means that for every unit of distance on the map with the smaller linear scale, the corresponding distance on the map with the larger linear scale will be twice as long.
What is the length of a werewolf?
The length of a werewolf can vary depending on the mythology or story it comes from. In general, werewolves are typically depicted as being similar in size to humans, but with more muscular and wolf-like features.
The height of a wave is twice the measure of its what?
The height of the wave, above the rest position, is its Amplitude. Twice the amplitude is the distance from the deepest point to the highest point.
When a tree cast a 20 foot shadow a man 6 feet tall casts a 3 foot shadow how tall is the tree?
The man is twice as high as his shadow. Therefore, the tree must also be twice as high as its shadow, which would make the tree 40 feet tall.
How tall is a flagpole that casts a shadow 28 feet long when a man 4 feet tall casts a shadow 8 feet long?
The flagpole is 14 feet tall - all of the shadows (at that particular time of day) are twice the length of the object. You can compare any values at that time, and the ratios are the same: x/ 28 = 4/8 (= 1/2) x = 14
What is the height of a flagpole if a person 5 feet tall casts a 10 foot shadow at the same time that the flagpole casts a 40 foot shadow?
The flag pole would be 20 feet. (You can see that the shadows are twice as long.) At a given time of the day, the length of a shadow cast by any object will have the same relationship to its actual height as all other objects. Here the ratio is 5/10 = x/40 and multiplying both sides by 40, 20 = x.
What is the limit of the object distance to produce a real image?
The limit of the object distance to produce a real image is twice the focal length of the lens or mirror. This occurs when the object distance is equal to the focal length, resulting in the image distance being at infinity. At distances greater than twice the focal length, the real image becomes smaller and inverted.
What happens during total lunar eclipse?
The Sun is bright, and the Earth is a rock about 8,000 miles across. So the Earth casts a shadow out into space. The Moon orbits the Earth, and about twice a year the Moon goes into the Earth's shadow. We call this a "lunar eclipse".
How long is a piece of twine?
The length of a piece of rope is twice the distance from the middle to one end.
If an object is placed at a distance greater than twice the focal length of a convex lens what type of an image will be produced?
If an object is placed at a distance greater than twice the focal length of a convex lens, a real and inverted image will be produced. The image will also be smaller than the object.
How much fencing will be needed to fence a property that is 78 meters long and 65 meters wide?
For a rectangle, calculate twice the length, plus twice the width.For a rectangle, calculate twice the length, plus twice the width.For a rectangle, calculate twice the length, plus twice the width.For a rectangle, calculate twice the length, plus twice the width.
How high is a tree that casts a 24 ft shadow at the same time a 12 ft post casts a shadow which is 12 ft long?
As the sun is far enough away, the rays of light are effectively parallel. This produces similar triangles with the ratio of sides the same in each case. As the shadow of the post is 12 ft and the shadow of the tree is 24 ft, the sides of the triangle of the tree are double that of the post. Assuming the post is parallel to the tree, the tree's height is twice the height of the post → tree = 12 ft × 2 = 24ft high.
What is the perimeter in feet of a rectangle whose length is twice its width and whose width is 9 feet?
If the width is 9' and the length is twice that, the length is 18'; the perimeter is twice the length plus twice the width, which is 36' + 18' = 54 feet.
What can be concluded about a rectangles width if the ratio of length to perimeter is 1 to 3?
The width is half the length: The perimeter is twice the length plus twice the width. If the perimeter is 3 times the length, twice the width must be the length.
What is the characteristics of diameter?
The length of the space between two sides of a circle passing through the radius, Alternatively it is twice the length of the radius. This is the distance from the centre of the circle to any point on the circumference.
