## Question 16

True or False: The addition of a vector to a point produces a new point.

What is the meaning of the following two images?

These images were inserted here simply to insert some space between the questions and the answers to keep them from being visible on the screen at thesame time.

This image was also inserted for the purpose of inserting space between the questions and the answers.

True

True. In fact, when the lengths of the vectors are the same and they are opposite in direction, the length of the sum of the two vectors is zero.

False. When you add vectors, the order in which you add the vectors doesn't matter. The result will be the same no matter the order in which you add them.

False. If an object is registered as an ActionListener on a button, the actionPerformed method belonging to the object is called each time the user clicks the button.

False. In order to cause a point to remain in the same location relative to world coordinates, its values relative to the current coordinate frame must bemodified each time the coordinate frame is modified.

True

False. The head-to-tail rule applies for the sum of any number of vectors in any number of dimensions (but it is difficult to draw in more than threedimensions).

False. It doesn't matter whether or not the coinciding tails are drawn at the origin. The head-to-tail rule still holds true.

True. This is a description of the head-to-tail rule.

False. While it's legal to draw a vector anywhere in space, certain positions may have advantages over other positions in some cases.

True

False. When you draw a vector, you can draw it anywhere in space, and one position is equally as valid as any other position.

True

False. The sum of a vector and a point is another point .

False. The length of a 2D vector is equal to the length of the hypotenuse of a right triangle formed by the lengths of the horizontal and vertical componentsof the vector.

True

what does nano mean?
nano basically means 10^(-9). nanometer is a unit to measure length.
Bharti
do you think it's worthwhile in the long term to study the effects and possibilities of nanotechnology on viral treatment?
absolutely yes
Daniel
how to know photocatalytic properties of tio2 nanoparticles...what to do now
it is a goid question and i want to know the answer as well
Maciej
Abigail
for teaching engĺish at school how nano technology help us
Anassong
Do somebody tell me a best nano engineering book for beginners?
what is fullerene does it is used to make bukky balls
are you nano engineer ?
s.
fullerene is a bucky ball aka Carbon 60 molecule. It was name by the architect Fuller. He design the geodesic dome. it resembles a soccer ball.
Tarell
what is the actual application of fullerenes nowadays?
Damian
That is a great question Damian. best way to answer that question is to Google it. there are hundreds of applications for buck minister fullerenes, from medical to aerospace. you can also find plenty of research papers that will give you great detail on the potential applications of fullerenes.
Tarell
what is the Synthesis, properties,and applications of carbon nano chemistry
Mostly, they use nano carbon for electronics and for materials to be strengthened.
Virgil
is Bucky paper clear?
CYNTHIA
so some one know about replacing silicon atom with phosphorous in semiconductors device?
Yeah, it is a pain to say the least. You basically have to heat the substarte up to around 1000 degrees celcius then pass phosphene gas over top of it, which is explosive and toxic by the way, under very low pressure.
Harper
Do you know which machine is used to that process?
s.
how to fabricate graphene ink ?
for screen printed electrodes ?
SUYASH
What is lattice structure?
of graphene you mean?
Ebrahim
or in general
Ebrahim
in general
s.
Graphene has a hexagonal structure
tahir
On having this app for quite a bit time, Haven't realised there's a chat room in it.
Cied
what is biological synthesis of nanoparticles
what's the easiest and fastest way to the synthesize AgNP?
China
Cied
types of nano material
I start with an easy one. carbon nanotubes woven into a long filament like a string
Porter
many many of nanotubes
Porter
what is the k.e before it land
Yasmin
what is the function of carbon nanotubes?
Cesar
I'm interested in nanotube
Uday
what is nanomaterials​ and their applications of sensors.
what is nano technology
what is system testing?
preparation of nanomaterial
how did you get the value of 2000N.What calculations are needed to arrive at it
