Vervaardiging

Volgorde van vervaardiging van met behulp van ‘n

eenvoudige prosesvloeidiagram.

‘n Prosesvloeidiagram se funksies is:

  • om aktiwiteite in ‘n proses van mekaar te skei;
  • om aktiwiteite in ‘n logiese orde te rangskik.

Elke soort aktiwiteit word deur ‘n raam / blok met ‘n bepaalde fatsoen voorgestel.

Skryf die verskillende stappe neer deur die aksie, materiaal en gereedskap wat daarvoor gebruik is saam te voeg in ‘n sin. Skryf slegs een werkwoord per sin.

Instruksies vir die maak van die houer

  1. Neem die templaat (patroon op grafiekpapier), die deurslagpapier en die karton en plaas dit in dié volgorde onder mekaar. Kram dit bo vas met ‘n krammasjien sodat dit nie skuif nie.
  2. Beantwoord die volgende vrae oor jou houer.
  • Hoeveel sye / kante het dit?
  • Hoeveel pare ewe groot sye / kante het dit?
  • Hoeveel rande het die houer?
  • Hoeveel hoeke het die houer?
  • Hoeveel flappe het die houer?
  • Hoeveel pare ewe groot flappe het die houer?
  • Gebruik ‘n HB-potlood en liniaal en trek die 2D-vorm op die karton oor. Trek eers die aaneenlopende lyne en dan die stippellyne. Loer of alles oorgetrek is.
  • Verwyder die krammetjies en knip die 2D-vorm uit op die aaneenlopende lyne.
  • Keep die stippellyne op die kant waar die deurslagpapiermerke is met ‘n skêr en liniaal. Doen dit op ‘n geskikte oppervlakte; oefen eers vooraf sodat jy nie die kepe te diep maak nie.
  1. Vou op die stippellyne met ‘n liniaal.
  2. Bring die tesselasie–ontwerp met ‘n potlood en met jou gunsteling templaat op die regte kant aan. Kleur die dele versigtig volgens jou gekose patroon in en trek die lyne met ‘n swart pen/ “fine-liner” donkerder.
  3. Voltooi die deksel van die houer volgens jou finale ontwerp (naam, ligbron, toetse, vrae).
  4. Gom die flappe met houtlym en vorm die 3D-houer. Hou stewig in posisie vas sodat die houer deeglik droog word.

Monteer die elektriese stroombaan in die houer. Maak gaatjies aan die een sy van die houer vir die konneksies.

Vervaardiging van deksel deur Leerder 1:

Assessering van vervaardiging Ja Nee
1. Die finale voorkoms is soos die gekose ontwerp.
2. Die naam , vrae en antwoorde is in gedrukte / stensil-vorm.
3. Die openinge vir die ligbron en gonser is netjies toegeplak met sellofaan en deurskynende kleeflint.
4. Die naam, vrae en antwoorde is netjies en deeglik vasgeplak of geskryf op potloodlyntjies wat na die tyd uitgevee word.
5. Die twintig spleetspelde / drukspykers of skroewe is deeglik aan die een kleur geleidingsdrade gesoldeer.
6. Die deksel pas stewig oor die onderste deel.
7. Die gate vir die geleidingsdrade stem ooreen met dié van die bodem.
8. Elke geleidingsdraad verbind ‘n vraag met die korrekte antwoord en die spleetspelde raak nie aan mekaar nie.
9. Die deksel se knip, keep, vou en die flappe se plakwerk is netjies gedoen.
10. Die deksel het ‘n netjiese, stewige vorm.

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.
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).
