Why doesnt a medium travel with the wave?
It is possible for a medium itself to travel, but in that case case it isn't called a wave, but a current. For example, water flowing in a river.
How do you know when something has the same velocity and when it doesnt?
By definition, it would have the same speed and direction as the compared object. This can be evidenced by the two objects having an unchanging spatial relationship: i.e. the objects remain the same direction and distance from each other.
What allows electricity to move through materials?
electricity doesnt move...its the electrons...rather free electrons in materrials that moves nd we call it as electric current
Is calories a scalar or a vector quantity?
well, by definition vector is something that has both direction and magnitude, in this case weight is only countable when gravity exists, and of course gravity has direction direction for vector doesnt have to be like north, south or within the plane because vectors are free and can be moved anywhere without changing its magnitude.
How does a pool heater work?
it doesnt work, it breaks it doesnt work, it breaks it doesnt work, it breaks
What is the reason for reverse saturation current?
its simple.reverse saturation current is because of the flow of minority carriers across the junction when the bias is changed suddenly from forward to reverse.this is why it doesnt depend on forward bias
Does a 1993 Honda Accord have reverse threads?
no it doesnt
How does reverse polarity help geophysicists?
it really doesnt
Why doesnt Louis sing in one direction?
he does or else they wouldnt be one direction
What doesnt involve direction?
Scalars Examples: Mass, Charge, Temperature, Density, Energy, Units of time like hours, minutes and seconds
How do you remove a gear knob in a v reg vauxhall corsa lift reverse?
You can first try to twist it in an anticlockwise direction and then pull but if that doesnt work make a cut around the material that bonds the knob to the lever. You can then pull it out.
Is there a difference between horizontal boring and directional boring?
Boring doesnt have direction but directional boring have direction
Does One Direction do drugs?
Doesnt everybody in the music field?
What causes fan to run in reverse?
(1)What happens when polarity of the fan is reversed? It depends upon your definitions of reversal of capacitor,in a series circuit reversing a capacitor in the actual sense means not a mechanical reversal by changing its metal leads,its just reversing the current direction in the capacitor. (2)Now next question is does fan capacitor have a polarity? Ofcourse it has,all capacitors have polarity,but fans capacitor is not electrolytic capacitor,so it doesnt have inbuilt polarity. (3)How we recognize the polarity of capacitor of a ceiling fan? Since it doesnt have inbulid polarity,the direction of the current entering the mesh determines positive polarity and current leaving is assumed as negative polarity.while doing mathematical analysis we can take any convention it will not affects the magnitude since we are taking modulus in calculations. (4)Final Assumption reveling the facts about fans reverse rotation If we connect the fan in such a way that currrent is leaving or reversing the direction of current,the capacitor polarity changes and fan will rotate in reverse(since it is a single phase induction motor{note: rotating magnetic field and working of fan}),need of the capacitor is it gives the initial torque and technically improves the power factor,capacitor charges and discharges with respect to the frequency of the ac and gives the stability to the system,its efficiency will be lower and speed reduces if we remove the capacitor theoratically,so finally you can say the fan rotates reverse if we change the polarity of the capacitor(indirect meaning of changing direction of current).if you want any simple mathematical analysis of the detailed explanation,mail me at "ellipsis047@gmail.com" or call me 07259434969 "Sreenath SM(India)".i can make you understand the basis of all analog and electrical circuits.
Why does no one capitalize One Direction?
its abbreviated 1D if thats what you meann..hhaha other wise its One Direction or one direction, doesnt matter.
Why one direction don't come in Slovenia?
There management doesnt let them:(
Does Naill Horan have a girlfriend?
no he doesnt not he said on xtra factor that he doesnt the only boy in one direction who does is loui tomlinson. However, after the shows finished One Direction performed a gig at Glasgow and afterwards Niall was seen 'romping' with a girl called Jessie English. There have been rumours suggesting they have continued their relationship even with Nialls busy schedule.
