Zad58 str 204
Z podanych wzorów fizycznych wyznacz wskazane wielkości.
a)P=d/m RT: M
b)f=9/5c + 32; c
c)s=vt+ at(kwadrat)/2 ;a
d)F=G Mm/r(kwadrat) ;m

Answer 1

A) P=d/M RT ; M
P=d/M RT ; M
MP=d/(R*T)
M=d/(R*T*P)

b) f=9/5 c+32 ; c
f-32=9/5 c
c= (5/9)*(f-32)

c) s=vt+at²/2 ; a
s-vt=+at²/2
2(s-vt)=+at²
2(s-vt)/t²=+a

d) F=G Mm/r² ; m
F*r²=G Mm
(F*r²)/GM = m

proszę o najj...

Answer 2

A) P = d / m RT | * m
Pm = dRT | : P
m = dRT / P
b) f = 9 / 5c + 32
9 / 5c = f - 32 | * 5 / 9
c = 5 / 9 ( f - 32 )
c) s = vt + at^2 / 2 | - vt
at^2 / 2 = s - vt | : t^2
a / 2 = ( s - vt ) / t^2 | x 2
a = 2( s - vt ) / t^2
d) F = G Mm/r^2 | * r^2
GMm = Fr^2 | : GM
m = Fr^2 / GM
