Inhoud

Aktiwiteit: om ‘n lys van moontlike uitkomstes vir eenvoudige eksperimente te maak [lu 5.9]

Bepaal die waarskynlikheid in die volgende gevalle:

1. Twee dobbelstene word gelyktydig gegooi. Wat is die waarskynlikheid dat een van die dobbelstene op ‘n 1 sal land?

_____________________________________________________________________

_____________________________________________________________________

2. Daar is twee paar wit en een paar swart sokkies in my laai. Wat is die waarskynlikheid dat ek ‘n wit sokkie sal uithaal sonder dat ek kyk wat ek doen?

_____________________________________________________________________

_____________________________________________________________________

3. In die messegoedlaai lê vyf vurke, vyf messe en ses lepels deurmekaar. Wat is die waarskynlikheid dat ek ‘n lepel uit die laai sal haal?

_____________________________________________________________________

_____________________________________________________________________

4. Wat is die waarskynlikheid dat ‘n muntstuk op “kruis” sal val as jy dit in die lug opskiet?

_____________________________________________________________________

_____________________________________________________________________

5. Kyk na die skets. Wat is die waarskynlikheid dat die wyser nie op P sal stop as jy hom draai nie?

Assessering

Leeruitkomste 5: Die leerder is in staat om data te versamel, op te som, voor te stel en krities te ontleed om gevolgtrekkings en voorspellings te maak, en om toevallige variasies te interpreteer en te bepaal.

Assesseringstandaard 5.9: Dit is duidelik wanneer die leerder ‘n lys moontlike uitkomste opstel vir eenvoudige eksperimente (insluitend die gooi van ‘n muntstuk, rol van ‘n dobbelsteentjie en die spin van ‘n draaibord).

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
Hello
Uday
I'm interested in Nanotube
Uday
this technology will not going on for the long time , so I'm thinking about femtotechnology 10^-15
Prasenjit
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?
