Why do they use p and q for object distance and image distance?

∙ 14y ago
The mathematical use of p and q for object distance and image distance is due to the simple likeness of p and q. They use p and q to show you how both distances are a like and yet exceedingly different. Some say that it is just the slightest amount of luck that they are a like like this, but those people are stupid because you and i know it is false

What is the Focal length of a plane mirror?
Infinity.because the distance of object from mirror"p" and the distance from image to mirror"q" are equal,so by using formula 1/f=1/p+1/q we can find the answer as the image of plane mirror is virtual,so"q" is taken negative,so putting values 1/f=1/p-1/p(bcz p=q) 1/f=0 f=1/0 and any thing divided by zero is infinity.
What is the equation you use to determine the momentum of an object?
momentum is described as mass times velocity. p=mv.
What is the equation you use to determine the momentum of an obect?
The momentum of an object is the product of its mass and its velocity. p = mv
What is the function of visual axis?
the image is passing through the pupil and create a image , :P
What is the equation for momentum?
Momentum of an object is defined as the product of the object's mass and its velocity.momentum (p), mass (m), velocity (v)p=m * vDefinition:Momentum-Measure of how hard it is to stop ans objectChange in time divided by change in speed, use the delta symbol for change (looks like a triangle).
Why the distance of the mirror image equal with distance of the mirror object?
coz miror reflects d same image
What is the relationship of the size of object and image to the distance of the object and image?
image distance is the distance from the point of incidence on the mirror, the where the image is reflected to.object distance is the distance from the actual object being reflected to the point of incidence on the mirror where it's reflected as an image.
What is the value of focal length of plane mirror?
Infinity.because the distance of object from mirror"p" and the distance from image to mirror"q" are equal,so by using formula1/f=1/p+1/qwe can find the answeras the image of plane mirror is virtual,so"q" is taken negative,so putting values1/f=1/p-1/p(bcz p=q)1/f=0f=1/0and any thing divided by zero is infinity.hope this helps

When to use the dot operator and when to use the arrow operator in c plus plus?
You use the dot operator when the left side is the name of the object or a reference to an object, and you use the arrow operator when the left side is a pointer to an object. Example: struct foobar x, *p= &x; x.field = p->field; (&x)->field = (*p).field;
How far an object has moved (speed x time)?
To measure smaller object use ruler or measuring tape. Or For long paths use laser distance measurer Or For further long distances use Side road millage stones Or For Still long distances JUST USE google earth :p Hope it helped
How much power is used to move a 13 N object a distance of 3m in 5 seconds?
Power=(Force X distance) / (time) P= (13N x 3m) / (5 sec) P= 7.8 Watts
Why microscope image move opposite direction?
The lens inverts the image. Like this drawing: p>()<d You are seeing the object backwards. There is a better picture at this web site: http://www.micrographia.com/tutoria/micbasic/micbpt03/micb0300.htm
What does ctrl plus p means?
If you press the keys Ctrl + p at the same time you will be able to use your printer.
Concave mirror with a focal length of 10cm creates a real image 30cm away on in princial axis how far from the mirror is its coresponding object?
1/f=1/p + 1/q f=focal length p=actual length of object q=imagine length plug&chug
What would be the image of a cut out letter P when it is being placed in front of a mirror?
The image would be P It would only be reversed if you turn the P to face the mirror, but if you put it in front of you facing you the image would be the same
How does the distance moved by an object between its starting point and its ending point compare with the displacement vector between the same point?
Displacement is how far the object is from the starting point, while distance traveled is the how far the object traveled all together. -Eric P
