Projekportefeulje

Opdrag 1a:

LU/AS 2.2

Soek voorbeelde van verskillende soorte houers in tydskrifte en knip dit uit. Sommige voorbeelde van houers word slegs vir ‘n SPESIFIEKE DOEL gebruik, soos ‘n eierhouer, ‘n melkbottel en ‘n gereedskaphouer. Ander houers is vir ALGEMENE GEBRUIK, soos ‘n mandjie of ‘n tas. Plak ten minste vyf voorbeelde van elke tipe houer in die raampies en voltooi die vrae oor elke prentjie.

Vrae:

1. Vir wie/waarvoor word dit gebruik?

2. Waarvan is dit gemaak?

3. Is dit relatief duur of goedkoop?

4. Kan dit herhaaldelik gebruik word of slegs een keer?

5. Is dit voordelig /bio-afbreekbaar vir die omgewing of vergaan dit moeilik en besoedel die omgewing?

6. Is dit duursaam of kan dit maklik breek?

Opdrag 2:

Om die spesifikasies van jou produk neer te skryf

2. Watter vorm sal dit hê?

3. Hoe sal dit lyk?

  • Watter soort karton sal jy gebruik vir die versterking aan die binnekant?
  • Watter tipe hout sal jy gebruik vir die versterking en versiering aan die buitekant?
  • Watter tipe kledingstof wil jy gebruik om die binnekant mooi af te rond? (satyn, sy, fluweel, vilt).

MAAK/ VERVAARDIGING

Opdrag 3:

Om ‘n kissie te maak

LU/AS 1.9

Instruksies vir die maak van die kissie.

  1. Plaas die net, die deurslagpapier en die karton in dié volgorde onder mekaar.
  2. Gebruik ‘n potlood en ‘n liniaal en trek die 2D-vorm op die karton oor. Trek eers die aaneenlopende lyne en dan die stippellyne af. Loer of alles oorgetrek is en maak seker dat dit nie skuif nie.
  • Wat is die doel van die aaneenlopende lyne?
  • Wat is die doel van die strepieslyne?
  • Knip die 2D-vorm uit op die aaneenlopende lyne met ‘n skêr.
  • Keep die stippellyne op die kant waar die deurslagpapiermerke is met ‘n els / skêr en ‘n liniaal. Doen dit op ‘n geskikte oppervlakte. Oefen eers vooraf sodat jy nie die kepe te diep maak nie.
  • Vou op die strepieslyne met ‘n liniaal.
  • Gom die flappe met lym en vorm die 3D-houer. Hou stewig in posisie vas sodat die houer deeglik droog word. (Moenie te veel gom gebruik nie. Die oppervlak moet net taai wees.)

Opdrag 4a:

Om te beplan vir die maak van die produk

LU/AS 1.9

Voltooi die volgende tabel deur die instruksies deur te lees en al die gereedskap, materiale en aksies onder die korrekte kolom neer te skryf.

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?

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).
