Inhoud

Onthou jy nog wat die woord ewewydig beteken? Skryf gou ‘n definisie neer:

_____________________________________________________________________

_____________________________________________________________________

_____________________________________________________________________

Kom ons val weg met ‘n paar “kopkrappers”!

Kyk na die sketse hieronder en beantwoord dan die vrae:

1. Is EF en GH ewewydig aan mekaar in:

A: __________________________________________________________________

B: __________________________________________________________________

2. Is C of K die verlenging van F?

Onthou jy nog?

is ‘n lyn: AB
is ‘n lynstuk: EF
is ‘n straal: CD

Twee lyne wat mekaar sny, vorm ‘n hoek .

Ons noem die punt waar die twee lyne ontmoet, die hoekpunt .

Ons skryf: ABC

  • Het jy geweet?

Die eenheid waarin ons hoeke meet, is graad . Ons druk die grootte van‘n hoek in grade uit. ‘n Hoek van 60 grade skryf ons so: 60º.

Daar is ‘n paar soorte hoeke wat jy moet ken:

Soorte hoeke
1. ‘n Omwenteling of volle draai is 360° groot.
2. ‘n Gestrekte hoek is ‘n halfdraai en is 180° groot.
3. ‘n Regte hoek is ‘n kwartdraai en is 90° groot.
4. ‘n Skerphoek is groter as 0°, maar kleiner as 90°.
5. ‘n Stomphoek is groter as 90°, maar kleiner as 180°.

Aktiwiteit: om hoeke te herken en te beskryf [lu 4.11]

1. Hoe goed ken jy nou jou hoeke?

Werk saam met ‘n maat en kyk of jy kan sê watter soort hoeke die volgende is:

1.1

Assessering

Leeruitkomste 4: Die leerder is in staat om gepaste meeteenhede, instrumente en formules in ‘n verskeidenheid kontekste te gebruik.

Assesseringstandaard 4.11: Dit is duidelik wanneer die leerder hoeke in twee-dimensionele vorms, drie-dimensionele voorwerpe en in die omgewing herken en beskryf.

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?
