advantages and disadvantagess of linear and nonlinear scale

linear scales have advantage
they are stndardised so can be used for all readings
disadvantage
cannot be used accurately for those readings ehich do not vary linearly with time
non linear advantage
sensitivity can be changed to support the reading
can be used suitably for all measurements

thank you very much Mr A* on land

aren't you free already
(im trapped in an island)

thanks again

my handwriting is horrible

do they reduce mrks for that

 

[gary221]

i dont think so...as long as ur writing is legible.

I hope not.. cuz then I am pretty sure they will reduce 5-10 marks off my paper :O

lmao i think i would loose atleast 15 for mine

I am paracticing paragraphs to improvwe my handwriting should have done this ten years a go

by the way mr A star you fogot to anwser disadvantages of nonlinear scale

disadvantage of non linear = advantage of linear ( just phrase it)

I am just thinking about the examiner who will be reading my GP essays... hahaha .. poor examiner.

Disadvantage = It is non-standarardized..

 

[megamind]

NICE ONE HAHA!

another question-what are the ranges of space,sky waves?

Question 2B.. the graph anyone?

 

[abruzzi]

That A2? Link the paper... please that way we'll be able to help better

Nope.. that's AS.
I have attached the file below.. please check qn no. 3 (b).

 

[megamind]

seriously you guys dont know the surface wave,sky wave used for radio communication,
and space waves for satellite

i just want to know their ranges

 

[megamind]

What happens when one of the slit is closed in YOung's double slit experiment.. ??????????? kindly reply

i dont know that too
anyone who can reply this

 

[syed1995]

seriously you guys dont know the surface wave,sky wave used for radio communication,
and space waves for satellite

i just want to know their ranges

Well Radio Waves frequency is 1x10^5 - 1x10^-1 and microwave is 1x10^-1 to 1x10^-3 ..

 

[zain786]

can you please help me in how to answer questions such as exam 9709/32/O/N10 the question 8 part b

its basically after making partial fractions...expanding it to ascending powers upto x^3 etc

how do you do these? plz help

 

[KurayamiKimmi]

seriously you guys dont know the surface wave,sky wave used for radio communication,
and space waves for satellite

i just want to know their ranges

surface wave: 1000 km
sky wave: worldwide by means of ionospheric reflection
space wave: line of sight including satellite communication
