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.

sure. what is your question?
okay, so you have 6 raised to the power of 2. what is that part of your answer
I don't understand what the A with approx sign and the boxed x mean
it think it's written 20/(X-6)^2 so it's 20 divided by X-6 squared
I'm not sure why it wrote it the other way
I got X =-6
ok. so take the square root of both sides, now you have plus or minus the square root of 20= x-6
oops. ignore that.
so you not have an equal sign anywhere in the original equation?

or infinite solutions?
The answer is neither. The function, 2 = 0 cannot exist. Hence, the function is undefined.

good afternoon madam
what is system testing
what is the application of nanotechnology?
In this morden time nanotechnology used in many field . 1-Electronics-manufacturad IC ,RAM,MRAM,solar panel etc 2-Helth and Medical-Nanomedicine,Drug Dilivery for cancer treatment etc 3- Atomobile -MEMS, Coating on car etc. and may other field for details you can check at Google
anybody can imagine what will be happen after 100 years from now in nano tech world
after 100 year this will be not nanotechnology maybe this technology name will be change . maybe aftet 100 year . we work on electron lable practically about its properties and behaviour by the different instruments
name doesn't matter , whatever it will be change... I'm taking about effect on circumstances of the microscopic world
how hard could it be to apply nanotechnology against viral infections such HIV or Ebola?
silver nanoparticles could handle the job?
not now but maybe in future only AgNP maybe any other nanomaterials
I'm interested in Nanotube
this technology will not going on for the long time , so I'm thinking about femtotechnology 10^-15
can nanotechnology change the direction of the face of the world

At high concentrations (>0.01 M), the relation between absorptivity coefficient and absorbance is no longer linear. This is due to the electrostatic interactions between the quantum dots in close proximity. If the concentration of the solution is high, another effect that is seen is the scattering of light from the large number of quantum dots. This assumption only works at low concentrations of the analyte. Presence of stray light.
