Preface

This module contains review questions and answers keyed to the module titled GAME 2302-0125: Vector Addition .

The questions and the answers are connected by hyperlinks to make it easy for you to navigate from the question to the answer and back again.

Question 1.

True or False: The sum of two vectors is another vector.

Question 2

True or False: The length of a 2D vector is equal to the square root of the length of the hypotenuse of a right triangle formed by the lengths of thehorizontal and vertical components of the vector.

Question 3

True or False: The sum of a vector and a point is another vector.

Question 4

True or False: A vector has only two properties: length and direction. It does not have a position property.

Question 5

True or False: When you draw a vector, you must draw it in a specific location.

Question 6

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

Question 7

True or False: It's legal to draw a vector anywhere in space. Therefore, drawing the vector in one position doesn't have any advantage over drawingit in another position.

Question 8

True or False: If you add two or more vectors to produce a sum vector, and then draw the vectors that were included in the sum with the tail of onevector coinciding with the head of the previous vector, the head of the last vector that you draw will be positioned at some particular point in space.

If you then draw the vector that represents the sum vector with its tail coinciding with the tail of the first vector that you drew, its head willcoincide with the head of the last vector that you drew.

Question 9

True or False: In order for the head-to-tail rule to apply, the coinciding tails must be drawn at the origin.

Question 10

True or False: The validity of the head-to-tail rule is limited to the sum of two vectors in two dimensions.

Question 11

True or False: A point has a location property. In fact that is the only property that a point does have. Because a point is simply a location inspace, that location is always specified relative to some coordinate frame.

Question 12

True or False: The location of a point in world coordinates is independent of the values of the coordinates of the point with respect to changes in thecoordinate frame.

Question 13

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

Question 14

True or False: The result of adding vectors depends on the order in which you add the vectors.

Question 15

True or False: The length of the sum of two vectors is not necessarily equal to the sum of the lengths of the two vectors.

anyone know any internet site where one can find nanotechnology papers?

Introduction about quantum dots in nanotechnology
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

Abigail
for teaching engĺish at school how nano technology help us
Anassong
Do somebody tell me a best nano engineering book for beginners?
there is no specific books for beginners but there is book called principle of nanotechnology
NANO
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
carbon nanotubes has various application in fuel cells membrane, current research on cancer drug,and in electronics MEMS and NEMS etc
NANO
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

s.
Graphene has a hexagonal structure
