Inhoud

Aktiwiteit: om getalle te herken om hulle te beskryf [lu 1.3.1]

1. Op bladsy 6 het jy gesien hoe ons groot getalle (honderdduisende) lees en in woorde skryf. In die voorbeeld hierbo kon jy sien hoe ons miljoene lees en skryf. Kyk weer goed daarna en skryf dan die volgende getalle in woorde:

1.1 4 136 284 _______________________________________________________

_____________________________________________________________________

1.2 8 247 009 _______________________________________________________

_____________________________________________________________________

1.3 3 006 500_______________________________________________________

_____________________________________________________________________

2. Hier is die getalle vir jou in woorde uitgeskryf; kyk of jy dit in syfers kan doen:

2.1 vyfmiljoen vierhonderdduisend agthonderd en sestien

____________________________________________________________________

2.2 tweemiljoen seshonderd en twintigduisend en agtien

____________________________________________________________________

2.3 twaalfmiljoen sewehonderdduisend en ses

____________________________________________________________________

Assessment

Leeruitkomste 1: Die leerder is in staat om getalle en hul verwantskappe te herken, te beskryf en voor te stel. Hulle kan ook met bekwaamheid en vertroue tel, skat, bereken en kontroleer tydens die oplos van probleme.

Assesseringstandaard 1.3: Dit is duidelik wanneer die leerder die volgende ware getalle herken, klassifiseer en voorstel om hulle te beskryf en te vergelyk

1.3.1: heelgetalle tot minstens 9-syfergetalle.

what is the application of nanotechnology?
Stotaw
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
Prasenjit
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
Azam
name doesn't matter , whatever it will be change... I'm taking about effect on circumstances of the microscopic world
Prasenjit
how hard could it be to apply nanotechnology against viral infections such HIV or Ebola?
Damian
silver nanoparticles could handle the job?
Damian
not now but maybe in future only AgNP maybe any other nanomaterials
Azam
can nanotechnology change the direction of the face of the world
Prasenjit Reply
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.

the Beer law works very well for dilute solutions but fails for very high concentrations. why?
