True or False?

## Question 18

The class named Graphics2D is a superclass of the class named Graphics .

True or False?

## Question 19

Translating the origin from the default position at the upper-left corner of a Canvas object to the center of the Canvas object is equivalent to creating a new coordinate frame as explained by Kjell.

True or False?

## Question 20

The default direction for increasing vertical coordinate values in a Canvas object is down the screen.

True or False?

## Question 21

The default direction for increasing horizontal coordinate values in a Canvas object is from right to left across the screen.

True or False?

## Question 22

According to Kjell, a line drawn on the screen using an object of the Line2D.Double class is a true line segment.

True or False?

## Question 23

Objects instantiated from the classes named Point2D.Double and Line2D.Double are well suited for inclusion in mathematical operations.

True or False?

## Question 24

Creation of 2D and 3D graphics requires that you always display the points.

True or False?

## Question 25

A vector is a geometrical object that has two properties: length and direction." He also tells us, "A vector does not have a position.

True or False?

## Question 26

A vector must always specify a position.

True or False?

## Question 27

Three real numbers are required to represent a vector in a 2D system.

True or False?

## Question 28

A column matrix can be used to represent a point and can also be used to represent a vector.

True or False?

## Question 29

Different column matrices can be used to represent the same vector in different reference frames, in which case, the contents of the matrices will bedifferent.

True or False?

## Question 30

The two (or three) real number values contained in a column matrix to represent a point specify an absolute location in space relative to the currentcoordinate frame.

True or False?

## Question 31

The two (or three) real number values contained in a column matrix to represent a vector (in 2D or 3D) specify a displacement of a specific distance from an arbitrary point in an arbitrary direction.

True or False?

## Question 32

With regard to a vector, in 2D, the two values contained in a column matrix represent the displacements along three orthogonal axes.

True or False?

## Question 33

In the case of 2D, the length of the vector is the length of the hypotenuse of a right triangle formed by the x and y displacement values.

True or False?

## Question 34

In 2D, the direction of a vector can be determined from the angle formed by the x-displacement and the line segment that represents the hypotenuse of aright triangle formed by the x, y, and z displacements.

True or False?

## Question 35

A point is an absolute location , but a vector is a displacement .

True or False?

## Question 36

This program instantiates objects from the following non-static top-level classes belonging to the class named GM2D01 :

• GM2D01.ColMatrix
• GM2D01.Line
• GM2D01.Point
• GM2D01.Vector

what is the stm
is there industrial application of fullrenes. What is the method to prepare fullrene on large scale.?
Rafiq
industrial application...? mmm I think on the medical side as drug carrier, but you should go deeper on your research, I may be wrong
Damian
How we are making nano material?
what is a peer
What is meant by 'nano scale'?
What is STMs full form?
LITNING
scanning tunneling microscope
Sahil
how nano science is used for hydrophobicity
Santosh
Do u think that Graphene and Fullrene fiber can be used to make Air Plane body structure the lightest and strongest. Rafiq
Rafiq
what is differents between GO and RGO?
Mahi
what is simplest way to understand the applications of nano robots used to detect the cancer affected cell of human body.? How this robot is carried to required site of body cell.? what will be the carrier material and how can be detected that correct delivery of drug is done Rafiq
Rafiq
what is Nano technology ?
write examples of Nano molecule?
Bob
The nanotechnology is as new science, to scale nanometric
brayan
nanotechnology is the study, desing, synthesis, manipulation and application of materials and functional systems through control of matter at nanoscale
Damian
Is there any normative that regulates the use of silver nanoparticles?
what king of growth are you checking .?
Renato
What fields keep nano created devices from performing or assimulating ? Magnetic fields ? Are do they assimilate ?
why we need to study biomolecules, molecular biology in nanotechnology?
?
Kyle
yes I'm doing my masters in nanotechnology, we are being studying all these domains as well..
why?
what school?
Kyle
biomolecules are e building blocks of every organics and inorganic materials.
Joe
anyone know any internet site where one can find nanotechnology papers?
research.net
kanaga
sciencedirect big data base
Ernesto
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
Maciej
Abigail
for teaching engĺish at school how nano technology help us
Anassong
How can I make nanorobot?
Lily
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
how can I make nanorobot?
Lily
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
how did you get the value of 2000N.What calculations are needed to arrive at it
Privacy Information Security Software Version 1.1a
