kak tolong bantu saya jawab soal ini please,secepatnya

ngerti ajakan tulisannya!! semoga membantu walaupun dikit

BESARAN dan SATUAN
• dimensi


Dimensi besaran turunan

(1) luas, A = s²
[A] → [L]²
satuan m²

(2) volume, V = r²
[V] → [L]³
satuan m³

(3) massa jenis ρ = m / V
[ρ] → [M] [L]⁻³
satuan kg m⁻³

(4) kecepatan v = S /t
[v] → [L] [T]⁻¹
satuan m s⁻¹

(5) percepatan a = ∆v /t
[a] → [L] [T]⁻²
satuan m s⁻²

(6a) gaya F = m a
(6b) (gaya) berat w = m g
[F] → [M] [L] [T]⁻²
[w]→ [M] [L] [T]⁻²
satuan N

(7) berat jenis, s = w / V
[s] → [M] [L] [T]⁻² / [L]³ = [M] [L]⁻² [T]⁻²
satuan N m⁻³

(8) tekanan P = F / A
[P] → [M] [L] [T]⁻² / [L]² = [M] [L]⁻¹ [T]⁻²
satuan Pa

(9) usaha W = F S
[W] → [M] [L] [T]⁻² • [L] = [M] [L]² [T]⁻²
satuan J

(0) daya, P = W/t
[P] → [M] [L]² [T]⁻² / [T] = [M] [L]² [T]⁻³
satuan W
