wyznacz wskazane zmienne ze wzorów, wiedząc, że wszystkie zmienne sa liczbami dodatnimi:
a) p=p₀+pgh; p₀, g
b) Q=mc(t₂-t₁); m,t₂
c) 1/F=f₂+f₁/f₁f₂; F, f₁
d) a=v₁-v₀/t; t,v₀
proszę o pomoc.

a) p₀ = p - pgh; pgh = p - p₀ /: ph => g = (p - p₀)/ph
b) m = Q/[c(t₂ - t₁)]; t₂ = Q/mc + t₁
c)
Ff_{1} - f_{2}f_{1} = - Ff_{2} => f_{1}(F - f_{2}) = - Ff_{2}
d) ;
