Analysis of the code

In this exercise, the puck makes a journey across the ice consisting of two sequential legs in different directions with different magnitudes ofvelocity. Although each leg involves motion along a line, the total trip is not along a line.

The objective of the script is to

• Compute and display the time required to traverse each leg of the trip based on the given information.
• Compute and display the magnitude and the angle of the displacement from start to finish.
• Compute and display the time required to complete the entire trip, which is the sum of the times from both legs.
• Compute and display the magnitude of the average velocity as the magnitude of the displacement divided by the total time.
• Recognize that the angle of the average velocity is the same as the angle of the displacement.

The getAngle function

The code in Listing 2 begins with the getAngle function that we developed and used an earlier module. The purpose of the function is to receive the adjacentand opposite side values for a right triangle as parameters and to return the angle in degrees in the correct quadrant.

I explained this function in an earlier module and won't repeat that explanation in this module.

Compute the time for each leg

Following the definition of the getAngle function, Listing 2 computes the time required to traverse each leg of the trip. For variable naming purposes, the two legs are identified as A and B.

Variable names that end with "mag" contain vector magnitudes. Variable names that end with "ang" contain vector angles. Variable names that endwith "vel" contain the magnitudes of straight-line, uniform velocities.

The time to complete each leg of the trip is computed by dividing the magnitude of the displacement vector for that leg by the magnitude of thestraight-line velocity for that leg. The resulting times have units of seconds, and are saved in the variables named timeA and timeB .

The overall displacement

The magnitude and angle of the overall displacement for the two-leg trip (identified by the variables named vecResultMag and vecResultAng respectively) are computed using procedures that were explained in an earlier module. Therefore, I won't repeat that explanation inthis module.

The magnitude of the overall displacement is stored in the variable named vecResultMag , and the angle for the overall displacement is stored in the variable named vecResultAng .

The total time

The total time for the trip, identified by the variable named totalTime , is computed as the sum of the times for the individual legs.

are nano particles real
yeah
Joseph
Hello, if I study Physics teacher in bachelor, can I study Nanotechnology in master?
no can't
Lohitha
where we get a research paper on Nano chemistry....?
nanopartical of organic/inorganic / physical chemistry , pdf / thesis / review
Ali
what are the products of Nano chemistry?
There are lots of products of nano chemistry... Like nano coatings.....carbon fiber.. And lots of others..
learn
Even nanotechnology is pretty much all about chemistry... Its the chemistry on quantum or atomic level

no nanotechnology is also a part of physics and maths it requires angle formulas and some pressure regarding concepts

what is variations in raman spectra for nanomaterials
ya I also want to know the raman spectra
Bhagvanji
I only see partial conversation and what's the question here!
what about nanotechnology for water purification
please someone correct me if I'm wrong but I think one can use nanoparticles, specially silver nanoparticles for water treatment.
Damian
yes that's correct
Professor
I think
Professor
Nasa has use it in the 60's, copper as water purification in the moon travel.
Alexandre
nanocopper obvius

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
if virus is killing to make ARTIFICIAL DNA OF GRAPHENE FOR KILLED THE VIRUS .THIS IS OUR ASSUMPTION
Anam
analytical skills graphene is prepared to kill any type viruses .
Anam
Any one who tell me about Preparation and application of Nanomaterial for drug Delivery
Hafiz
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
