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?




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 fullerene does it is used to make bukky balls
Devang Reply
are you nano engineer ?
fullerene is a bucky ball aka Carbon 60 molecule. It was name by the architect Fuller. He design the geodesic dome. it resembles a soccer ball.
what is the actual application of fullerenes nowadays?
That is a great question Damian. best way to answer that question is to Google it. there are hundreds of applications for buck minister fullerenes, from medical to aerospace. you can also find plenty of research papers that will give you great detail on the potential applications of fullerenes.
what is the Synthesis, properties,and applications of carbon nano chemistry
Abhijith Reply
Mostly, they use nano carbon for electronics and for materials to be strengthened.
is Bucky paper clear?
carbon nanotubes has various application in fuel cells membrane, current research on cancer drug,and in electronics MEMS and NEMS etc
so some one know about replacing silicon atom with phosphorous in semiconductors device?
s. Reply
Yeah, it is a pain to say the least. You basically have to heat the substarte up to around 1000 degrees celcius then pass phosphene gas over top of it, which is explosive and toxic by the way, under very low pressure.
Do you know which machine is used to that process?
how to fabricate graphene ink ?
for screen printed electrodes ?
