OPDRAG 3:

Teken nou ontwerpe in die volgende vierkante om aan te toon hoe jy jou houer wil versier om tekstuur daaraan te verleen. Omkring jou beste idee.

LU/AS 1.6

OPDRAG 4:

Watter gereedskap/toerusting gaan jy nodig hê om jou gekose patrone mee aan te bring? Maak die gereedskap bymekaar en bring dit solank skool toe.

LU/AS 1.8

1. Vereistes

Die deksel van jou houer moet stewig op die houer pas. Daar moet ook ‘n handvatsel wees waaraan jy die deksel kan oplig.

OPDRAG 5:

Ontwerp nou sommer vryhand ‘n drie-dimensionele bo-aansig en drie-dimensionele onder-aansig vir jou deksel. Omkring jou beste idee.

LU/AS 1.5

OPDRAG 6:

Beplan en maak

LU/AS 1.5

a) Watter gereedskap het jy nodig om die klei op uit te rol tot ‘n dikte van 5 mm? (Kies uit houtbord, kleimes, koekroller, koekmeel.)

- ‘n om die klei op glad uit te rol.

- ‘n om die klei mee uit te rol.

- ‘n om die deeg van die koekroller en houtbord los te sny.

- sodat die klei nie aan die bord of koekroller vassit nie.

b) Meet ‘n vierkantige teël met sye van 10 cm op ‘n stuk karton en knip dit uit. Dit gaan jou TEMPLAAT wees. Plaas die templaat op die uitgerolde klei en sny ses teëls uit. Gebruik ook die kleimes om die handvatsel en onderkant van die deksel te maak.

Versier die vertikale vlakke van jou houer (vier teëls).

Sny 5 mm aan weerskante (links en regs) van twee vertikale teëls af. Maak ook die rande grof met ‘n sosatiestokkie. Gebruik ook water indien nodig.

Heg die dele van die houer as volg (werk baie versigtig):

  • Plaas die teël wat die bodem vorm op ‘n groot, gesmeerde bakplaat.
  • Neem ‘n sosatiestokkie en maak die rand (10 mm) rondom grof.
  • Plaas die versierde teëls bo-op die bodem. Maak seker dat die rande deeglik heg en dat die rande regte hoeke vorm.
  • Plaas op ‘n plek waar dit deeglik kan droog word. Indien die klei gebak kan word, kan hy dit volgens die aanwysings in die oond bak.
  • Voltooi die deksel volgens jou ontwerp en plaas dit langsaan jou houer.
  • As jou houer en deksel klaar droog is en afgekoel het, kan jy dit met een kleur plakkaatverf verf. Daarna kan jy dit met ‘n deurskynende vernis verf, sodat die artikel geseël is en die kleur van die verf wat jy gebruik het, beter kan vertoon.

Klei is ‘n baie ou stof wat gebruik is om gebruiksartikels en juweliersware van te maak. Klei was redelik volop en daarom het mense dit gebruik. Reeds in die Steentydperk (12000 v.C.) toe die mense gebruiksartikels en wapens hoofsaaklik van klip en been gemaak het, het hulle begin om gebruiksartikels van klei te maak om hoofsaaklik kos en water in te bewaar.

Gedurende die Bronstydperk (3000 v.C.) het die mense begin om metale te smelt om gebruiksartikels en wapens te maak. Toe het die mense op groot skaal gebruiksartikels soos houers, bekers, potte, ens. van klei gemaak. Hulle het ook bakstene en teëls daarvan gemaak en so wonings gebou. Argeoloë wat opgrawings doen van antieke beskawings, kry gewoonlik baie voorwerpe en oorblyfsels van klei wat bogenoemde feite staaf.

Questions & Answers

Three charges q_{1}=+3\mu C, q_{2}=+6\mu C and q_{3}=+8\mu C are located at (2,0)m (0,0)m and (0,3) coordinates respectively. Find the magnitude and direction acted upon q_{2} by the two other charges.Draw the correct graphical illustration of the problem above showing the direction of all forces.
Kate Reply
To solve this problem, we need to first find the net force acting on charge q_{2}. The magnitude of the force exerted by q_{1} on q_{2} is given by F=\frac{kq_{1}q_{2}}{r^{2}} where k is the Coulomb constant, q_{1} and q_{2} are the charges of the particles, and r is the distance between them.

what is a capacitor?
Raymond Reply
Capacitor is a separation of opposite charges using an insulator of very small dimension between them. Capacitor is used for allowing an AC (alternating current) to pass while a DC (direct current) is blocked.

which has a higher temperature, 1cup of boiling water or 1teapot of boiling water which can transfer more heat 1cup of boiling water or 1 teapot of boiling water explain your . answer
Ramon Reply
I believe temperature being an intensive property does not change for any amount of boiling water whereas heat being an extensive property changes with amount/size of the system.
Someone
Scratch that
Someone
temperature for any amount of water to boil at ntp is 100⁰C (it is a state function and and intensive property) and it depends both will give same amount of heat because the surface available for heat transfer is greater in case of the kettle as well as the heat stored in it but if you talk.....
Someone
about the amount of heat stored in the system then in that case since the mass of water in the kettle is greater so more energy is required to raise the temperature b/c more molecules of water are present in the kettle
Someone

Two bodies attract each other electrically. Do they both have to be charged? Answer the same question if the bodies repel one another.
JALLAH Reply
No. According to Isac Newtons law. this two bodies maybe you and the wall beside you. Attracting depends on the mass och each body and distance between them.

Are you really asking if two bodies have to be charged to be influenced by Coulombs Law?

What is specific heat capacity
Destiny Reply
Specific heat capacity is a measure of the amount of energy required to raise the temperature of a substance by one degree Celsius (or Kelvin). It is measured in Joules per kilogram per degree Celsius (J/kg°C).
