Hoe om ‘n ruitnet te gebruik

‘n ruitnet

Om 'n spesifieke plek se ligging op 'n plan of kaart aan te dui, is baie maklik as daar 'n ruitnet is. Dit is lyne wat op die kaart ingetrek word wat die kaart in klein vierkantige blokkies verdeel. Aan die bokant van die kaart word elke blokkie dan 1, 2, 3, ens. genommer. Aan die kant van die kaart word die syfers A, B, C, ens. aangebring.

Ons gebruik dié letters en syfers dan om aan elke blokkie 'n naam te gee.

Voorbeeld:

1 2 3
A A
B B
C C
3 2 3

As jy nou wil aandui waar die vliegtuig geleë is, sê ons dit is geleë in blok B2 .

Aktiwiteit 1

Om ligging te bepaal deur die gebruik van ‘n ruitnet [lu 1.3, 1.4]

Dui die ligging van die volgende voorwerpe aan soos wat dit in die voorbeeld hierbo voorkom:

1. man ...............................................................................................................

2. boom ..............................................................................................................

3. hond ..............................................................................................................

4. huis ...............................................................................................................

Bestudeer die volgende ruitnet:

1 2 3 4 5
A e n r g l A
B j q b t p B
C w k v x d C
D c y o I v D
E h m f s a E
1 2 3 4 5

Bestudeer nou die volgende gekodeerde boodskap wat volgens die ruitnet se kode geskryf is en ontsyfer dit. 'n Kommapunt (;) dui die einde van 'n woord aan.

A1 C2; B3 A5 D2; D4 A2; C2 E5 E5 B5 E4 B4 E5 C5; C1 E5 E5 A3; B3 A5 D2; B1 D2

....................................................................................................................

Skryf nou jou eie boodskap deur van die ruitenetkode gebruik te maak. Ruil jou geheime boodskap uit met 'n klasmaat en ontsyfer mekaar se boodskappe.

Assessering

Leeruitkoms 1: aardrykskundige ondersoek

Die leerder is in staat om ondersoekvaardighede te gebruik om aardrykskundige en omgewingsbegrippe en -prosesse te ondersoek.

Assesseringstandaard

Dis duidelik wanneer die leerder

1.3 simbole identifiseer wat in verskillende soorte kaarte gebruik word (insluitend planaansigte, ruitenet- en kaartsleutels).

1.4 plekke se ligging vind deur ‘n eenvoudige ruitenetverwysingstelsel en rigting te gebruik.

what is fullerene does it is used to make bukky balls
Devang Reply
are you nano engineer ?
s.
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.
Tarell
what is the actual application of fullerenes nowadays?
Damian
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.

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.
