Bestudeer ‘n stoel

  • Wat benodig ons om ‘n stoel te maak?
  • Dit moet gemaklik wees.
  • Dit moenie kan breek nie.
  • Wat is nog belangrik?Gaan sit op die verskillende stoele in jou huis.
  • Waarvan is dit gemaak?
  • Wat is hulle goeie eienskappe?
  • Wat is hulle slegte eienskappe?

EBWLU 2
EKONOMIESE SIKLUS Die leerder kan kennis en begrip van die ekonomiese siklus in die konteks van ‘die ekonomiese probleem toon’.
Assesseringstandaarde(ASe)
Dit is duidelik wanneer die leerder:
1.2 kan verduidelik dat behoeftes en begeertes onbeperk en veranderlik kan wees en deur maats, die media en die ontwikkeling van nuwe produkte en dienste deur sakeondernemings beïnvloed word;1.3 pryse op verskillende soorte pryskaartjies en etikette kan lees en identifiseer;1.4 kleingeld bereken nadat eenvoudige goedere en dienste gekoop is;1.5 uitdrukking gee aan die belangrikheid van en maniere om geld en ander hulpbronne soos water en elektrisiteit te bespaar en nie te vermors nie.
SOSIALE WETENSKAPAARDRYKSKUNDELU 3
ONDERSOEK VAN VRAAGSTUKKE Die leerder kan ingeligte besluite oor sosiale en omgewingsvraagstukke en -probleme neem.
Assesseringstandaarde(ASe)
Dit is duidelik wanneer die leerder:
3.1 omgewingsvraagstukke op die plek waar die leerder woon of skoolgaan, identifiseer en beskryf;3.2 die faktore wat tot die probleem aanleiding gee, identifiseer (faktore wat die vraagstuk affekteer);3.3 die impak van die probleem op die plek en mense (huis, skool, plaaslike omgewing) identifiseer [faktore wat die vraagstuk affekteer].
geskiedenisLU 1
GESKIEDKUNDIGE ONDERSOEKDie leerder kan ondersoek-vaardighede gebruik om die hede en verlede te ondersoek.
Assesseringstandaarde(ASe)
Dit is duidelik wanneer die leerder:
1.1 inligting uit geskiedkundige bronne wat deur die onderwyser verskaf is (bv. prente, foto’s voorwerpe, mense) verkry [werk met bronne].
tegnologieLu 1
TEGNOLOGIESE PROSESSE EN VAARDIGHEDE Die leerder is in staat om tegnologiese prosesse en vaardighede eties en verantwoordelik toe te pas deur gepaste inligtings- en kommunikasietegnologie te gebruik.
Assesseringstandaarde(ASe)
Dit is duidelik wanneer die leerder:

Assesseringstandaarde(ASe)
Dit is duidelik wanneer die leerder:
1.8 ( Visuele Kuns ) – die onmiddellike omgewing ondersoek deur die elementêre funksies van lyn, vorm, kleur en kontras in twee- en driedimensionele werk te gebruik;

Memorandum

Die leerders moet verskillende besighede besoek om pryse te vergelyk. Hulle moet ook besef dat die pryse sal verskil as gevolg van die gehalte van die papier. Maak hulle ook daarvan bewus dat die prys van papier kan wissel as gevolg van die aanvraag daarvoor (EBW 1.2, 1.3).

In ‘n Wiskunde-les kan die pryse van die papier vergelyk word en ook bepaal word hoeveel kleingeld hulle moet kry as hulle ‘n sekere bedrag geld ontvang het (EBW 1.4 ).

Die leerders word daarvan bewus gemaak dat verskillende materiale verskillende gebruike het. Meubels is gewoonlik net van hout gemaak, maar nou word daar ook van plastiek en aluminium gebruik gemaak. Tuinstoele word van plastiek gemaak, want dit is lig en maklik om te dra en word ook maklik skoon gemaak. Leerders moet die verskillende stoele by hulle huise bestudeer. Hulle kan ook prente van verskillende stoele skool toe bring en dit bespreek. Bespreek waarvan die stoele gemaak is en wat die doel of gebruike van die stoel is (NW 1.2 ).

Indien enige van die produkte plaaslik vervaardig is, maak die leerders bewus daarvan (Aardrykskunde 1.2).

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 the direction and net electric force on q_{1}= 5µC located at (0,4)r due to charges q_{2}=7mu located at (0,0)m and q_{3}=3\mu C located at (4,0)m?

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

how do lnternal energy measures

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

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).
