Answer

d

20.4 m\text{20.4 m}

Step-by-step solution

3 steps

Hapa kuna majibu kwa maswali yako:

Part a

Ili kupunguza kelele kutoka studio, marekebisho mawili ya kimwili yanaweza kufanywa kwenye kuta

  • Kuweka vifaa vinavyofyonza sauti (kama vile paneli za akustiki, povu, au pamba ya madini) kwenye kuta ili kupunguza mwangwi na upitishaji wa sauti.
  • Kuongeza unene au msongamano wa kuta, au kujenga kuta mbili zenye nafasi ya hewa katikati, ambayo hufanya kazi kama kizuizi bora cha sauti.

Part b

Meneja anapaswa kusakinisha *kioo cha convex

Sababu: Kioo cha convex hutoa eneo pana la kuona (wider field of view) ikilinganishwa na kioo cha kawaida (plane mirror). Hii inamaanisha meneja ataweza kuona sehemu kubwa zaidi ya ukumbi kutoka dawati la mapokezi, na hivyo kuboresha usalama na ufuatiliaji.

Part c

Shati la njano la Arinda linaweza kuonekana kijani wakati taa za kijani zinapowashwa kwa sababu

Rangi ya njano huonekana kwa sababu inakisi mwanga wa kijani na mwekundu. Wakati taa za kijani pekee zinapowashwa, shati la njano litaakisi tu sehemu ya kijani ya mwanga, na hivyo kuonekana kijani. Hakuna mwanga mwekundu wa kuakisiwa, hivyo sehemu ya "njano" inayotokana na mwekundu haionekani.

Part d

20.4 m\text{20.4 m}

Ili kukokotoa urefu wa ukumbi, tutatumia fomula ya umbali

  1. Tambua data uliyopewa.

    Kasi ya sauti (vv) = 340 m/s340 \text{ m/s}
    Muda (tt) = 0.12 s0.12 \text{ s}

  2. Kokotoa umbali wa jumla uliosafiri na sauti.

    Kumbuka kuwa sauti husafiri kwenda na kurudi (echo).

    Umbali wa jumla=v×t\text{Umbali wa jumla} = v \times t Umbali wa jumla=340 m/s×0.12 s\text{Umbali wa jumla} = 340 \text{ m/s} \times 0.12 \text{ s} Umbali wa jumla=40.8 m\text{Umbali wa jumla} = 40.8 \text{ m}

  3. Kokotoa urefu wa ukumbi.

    Urefu wa ukumbi ni nusu ya umbali wa jumla uliosafiri na sauti.

    Urefu wa ukumbi=Umbali wa jumla2\text{Urefu wa ukumbi} = \frac{\text{Umbali wa jumla}}{2} Urefu wa ukumbi=40.8 m2\text{Urefu wa ukumbi} = \frac{40.8 \text{ m}}{2} Urefu wa ukumbi=20.4 m\text{Urefu wa ukumbi} = \boxed{\text{20.4 m}}

    Urefu wa ukumbi ni 20.4 m.
