What does signing 3 x's in sign language mean?
If a person were to form the sign in ASL for "X" and move it back and forth a few times by a flick of the wrist, it is the sign for "need" or "should", depending on what non-manual behaviors (facial expression, etc) are used. If the sign is made by actually making shapes of X's with the first two pointer fingers, whereby they are touching to form an X, while moving from top part of body in front of body, not touching it), and then tapping those first fingers three times while moving the hands slightly in a down motion, then it could be the sign for "Amsterdam".
what does tangential mean?
a person that goes off subject while explaining their past
What is the difference between magnitude and direction?

How do you write pascal tringle in php using while loop?
function pascal($depth){ $row = array(1); while($depth > 0){ $newRow = array(1); for($n = 1; $n < count($row); $n++){ $newRow[] = $row[$n - 1] + $row[$n]; } $newRow[] = 1; $depth --; echo implode(' ', $newRow) . "\n"; $row = $newRow; } }
How is the image in a plane mirror different from the object itself?
The image in a plane mirror is laterally inverted, meaning left and right are switched, while the object itself is not inverted. The image appears to be the same distance behind the mirror as the object is in front of it. The size of the image is the same as the size of the object.
What is the difference between a virtual image and a real image?
A virtual image is formed by light rays that appear to diverge from a point behind a mirror or lens, while a real image is formed by light rays that converge at a point in front of a mirror or lens.
How can you distinguish between a plane concave and a convex mirror without touching them?
One way to distinguish between a plane concave and convex mirror without touching them is to observe their reflected images. A concave mirror will produce an upright and magnified image of an object placed in front of it, while a convex mirror will produce an upright and diminished image. Another way is to look at the reflection of a distant object – a concave mirror will form a real image, while a convex mirror will create a virtual image.
How would the eye perceive an image created by a concave mirror and by a convex mirror?
The image formed by a concave mirror can be real or virtual, depending on the object's position relative to the mirror. A real image is formed in front of the mirror and can be projected onto a screen, while a virtual image is formed behind the mirror and cannot be projected. Conversely, a convex mirror always produces a virtual, upright, smaller image of the object. The image appears closer to the mirror than the actual object and does not form a focused point.
What will the image produced by a concave mirror be?
A concave mirror can produce a real or virtual image, depending on the location of the object. Real images are formed in front of the mirror and can be projected onto a screen, while virtual images are formed behind the mirror and cannot be projected. The characteristics of the image, such as magnification and orientation, are determined by the mirror's focal length and the object's distance from it.
What are the differences between a virtual image and a real image?
A virtual image is formed by light rays that appear to diverge from a point behind a mirror or lens, while a real image is formed by light rays that converge at a point in front of a mirror or lens. Real images can be projected onto a screen, while virtual images cannot.
Is a plane mirror upright or inverted?
Actually a plane mirror inverts an image not side to side, but front to back. If you hold up your right hand in front of a mirror, the images of the parts of your hand closest to you will be the farthest away. It is this inversion that turns a left hand into a right hand, while leaving the thumbs on both hands pointing in the same direction.
What is a difference between the mirror image and the object?
A mirror image is a reflection that appears to be reversed left to right, while an object is a physical entity that exists in space. In a mirror image, the image appears as if you were looking at the object's reflection in a mirror.
What is a example of a reflection in a flat mirror?
An example of reflection in a flat mirror is when you see your own reflection while standing in front of it. The light rays from your body strike the mirror and reflect back towards you, allowing you to see your image.
What is the sign for object and image distances that are measured on the front side of a mirror?
Regardless of which side of the mirror you designate as the positive side, one of them is positive and the other one is negative, since the object and image are always on opposite sides of the mirror. BTW ... If the mirror is flat, then their absolute values are equal.
What happens to image if it moves closer to plane mirror?
If an image moves closer to a plane mirror, the distance between the object and the mirror stays the same while the image moves towards the mirror. As the image gets closer to the mirror, it appears to move further away from the viewer. The size of the image remains the same, but its apparent distance changes.
What kind of image is produced in a convex mirror?
The other uses of concave mirrors are: 1. Dental use - It focuses the light onto the area of the mouth. 2. Men use- This kind of mirror is great use for shaving. 3. Women use- This kind of mirror is great while applying makeup.
