Voordat jy enige van die aktiwiteite kan doen, moet jy jou liggaam opwarm. Die opwarmingsoefening sal verhoed dat jy gedurende die danse seerkry en sal die aktiwiteite makliker maak om uit te voer.
Aktiwiteit 1
Om op te warm en vaardigheid te ontwikkel [lu 1.1]
Dit sal makliker en meer pret wees as jy die opwarming met musiek doen. Moenie musiek kies wat te vinnig is nie.
Voorbereiding - staan met jou voete heupwydte van mekaar af, voete wys vorentoe, arms af.
Dit is belangrik om jou liggaamslyn te behou om die spesifieke spiere wat opgewarm word te isoleer.
Korrekte liggaamslyne sal beserings verhoed.
Beweeg slegs die liggaamsdele en spiere soos voorgeskryf.
Asemhalingsoefening
Haal asem in deur die neus vir vier tellings en lig die arms geleidelik sywaarts op.
Strek jou ruggraat.
Asem uit deur jou mond vir vier tellings en laat sak jou arms geleidelik.
Herhaal asemhalingsoefening.
Staan met jou voete heupwydte van mekaar af – knieë effens gebuig – arms af langs jou sye.
Kop- ennek- isolasies
Staan met jou voete heupwydte van mekaar af, voete vorentoe, arm langs sye.
Laat sak jou kop en beweeg dit dan van, kant tot kant (herhaal agt keer).
Maak halfsirkels met jou kop van regs na links, dan links na regs (herhaal agt keer):
moenie enige ander deel van jou liggaam beweeg nie.
hou voete stewig op die vloer.
moenie jou knieë sluit nie.
Skouer-isolasies
Lig jou regterskouer, sak, lig dan jou linkerskouer, sak (herhaal agt keer).
Draai regterskouer, dan linkerskouer (herhaal agt keer).
Kombineer kop- en skoueroefeninge:
kop op, af, regs, links, draai
skouers op, af, draai
herhaal agt keer
Hou die res van jou liggaam stil.
Probeer jou skouers so hoog as moontlik oplig sodat die strek effektief kan wees.
Moenie jou kop beweeg nie; kyk vorentoe.
Armopwarming
Voorbereiding: staan met jou voete heupwydte van mekaar af – arms langs sye – moenie jou knieë sluit nie – skouers vierkantig vorentoe – trek maagspiere in – hou boude in:
ons gaan slegs die arms opwarm – moenie enige ander deel van jou liggaam beweeg nie;
beheer die beweging van jou arms.
Lig reguit arms op na die kante – skouerhoogte – en laat sak arms (herhaal agt keer).
Lig arms reguit voor op – skouerhoogte – laat sak arms (herhaal agt keer).
Kombineer armbewegings (herhaal agt keer).
Buig arms by die elmboog – vorentoe – en sak (herhaal agt keer).
Lig arms vorentoe op – buig arms by die elmboë en maak arms reguit (herhaal agt keer).
Kombineer armbewegings (herhaal agt keer).
Bolyfopwarming
Voorbereiding: staan regop – arms langs sye – knieë effens gebuig –maag in – boude in
Maak seker jou heupe wys vorentoe.
Moenie jou bene of heupe beweeg nie.
Hou jou voete stewig op die vloer.
Buig jou bolyf na die regterkant – kyk vorentoe (herhaal agt keer).
Buig bolyf na links – kyk vorentoe (herhaal agt keer).
Swaai jou bolyf van regs na links – begin beweging regop en beweeg afwaarts in ‘n semi-sirkel – eindig weer regop links. (herhaal agt keer):
beheer jou swaaie.
hou jou balans.

you have been hired as an espert witness in a court case involving an automobile accident. the accident involved car A of mass 1500kg which crashed into stationary car B of mass 1100kg. the driver of car A applied his brakes 15 m before he skidded and crashed into car B. after the collision, car A s
can someone explain to me, an ignorant high school student, why the trend of the graph doesn't follow the fact that the higher frequency a sound wave is, the more power it is, hence, making me think the phons output would follow this general trend?
Nevermind i just realied that the graph is the phons output for a person with normal hearing and not just the phons output of the sound waves power, I should read the entire thing next time
Joseph
Follow up question, does anyone know where I can find a graph that accuretly depicts the actual relative "power" output of sound over its frequency instead of just humans hearing

A string is 3.00 m long with a mass of 5.00 g. The string is held taut with a tension of 500.00 N applied to the string. A pulse is sent down the string. How long does it take the pulse to travel the 3.00 m of the string?
