  • Plak dit op die folio wat jou opvoeder aan jou sal gee.
  • Dui die simmetrie-as met ‘n kleurkryt aan. (Gebruik jou liniaal!)

2. Voer die volgende opdragte uit:

  • Trek nou die vorms wat jy vir die tabel in aktiwiteit 1.7 gebruik het, netjies oor op papier (vra jou opvoeder). Jy kan dit so groot trek as wat jy wil.
  • Dui die simmetrie-asse netjies aan.

Aktiwiteit 6:

Om 3d-voorwerpe te ondersoek en te vergelyk [lu 3.3.1]

Om 3d-voorwerpe te herken [lu 3.3.1]

Ons het nou baie met 2-dimensionele vorms gewerk. Nou gaan ons 3-dimensionele figure van naderby bekyk.

1. Hou ‘n klasbespreking oor wat die verskil is tussen 2-dimensionele vorms en 3-dimensionele voorwerpe.

2. Hoe sal jy daarvan hou om ‘n argitek en bouer te wees? Jy en ‘n maat het nou die geleentheid om die skool van jul drome te bou! Julle benodig

  • ‘n groot stuk karton
  • gom en skêr
  • vuurhoutjiedosies, ens. (Gebruik jul eie, oulike idees!)

Hierdie skool moet klaskamers hê en daar moet ’n ronde swembad wees. Natuurlik wil julle ’n rekenaarsentrum en ’n saal ook hê. Die kleedkamers en die rugbyveld moet sommer naby aan mekaar geleë wees.

Hier volg bruikbare inligting. Bestudeer dit eers voordat julle begin werk.

’n Struktuur soos ’n vuurhoutjiedosie word ’n REGHOEKIGE PRISMA genoem, want al die platvlakke is reghoeke.

’n KUBUS is ’n spesiale soort prisma, omdat die sye van ’n kubus ewe lank is en die syvlakke ewe groot is.

3. Wanneer julle model klaar is, moet julle die onderstaande tabel voltooi. Kyk na die figure wat julle gemaak het. As die saal bv. ’n reghoekige prisma is, kom dit in daardie kolom.

Aktiwiteit 7:

Om patrone van geometriese vorms te maak en te beskryf in terme van tessellasies [lu 3.5.1]

Tesselasies

Dink ’n bietjie hoe teëls teen ’n muur of op die vloer van ’n badkamer gelê word. Die teëls pas presies teen mekaar. Die spasies wat jy sien, is net daar vir die sement of gom sodat die teëls stewig vasgeheg kan word en nie los kan kom nie.

Die teëls lyk gewoonlik só as dit gelê word:

Ons sê die teëls TESSELEER omdat hulle PRESIES, sonder tussenruimtes, inmekaar pas.

Aktiwiteit 9:

Om patrone van geometriese vorms te maak en te beskryf in terme van tessellasies [lu 3.5.1]

1. Gaan kyk vanmiddag by die huis na die teëls in jul badkamer, kombuis of enige ander vertrek in die huis. Jy kan ook na die teëls op die vloer of teen die mure van enige winkel in jou omgewing gaan kyk. Maak ‘n skets daarvan in die blok hieronder

2. Kyk nou weer na die skets van die teëls hierbo. Sien jy dat die binneste teëls reghoeke is en dat die buitenste teëls driehoeke is.

Maak nou jou eie patrone met ’n kombinasie van

  • driehoeke
  • vierhoeke
  • vyfhoeke
  • enige kreatiewe vorm

Gebruik die kolletjiespapier

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

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.

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).
