a)
P = d/M * RT
MP = dRT
M = d/P * RT = d/PRT
b)
f = 9/5c + 32
5f = 9c + 5 * 32
9c = 5 - 5 * 32
9c = 5(1 - 32)
c = 5(1 - 32)/9
c)
s = vt + at²/2
2s =2vt + at²
at² =2s - 2vt =2(s - vt)
a = 2(s - vt)/t²
d)
F =G * Mm/r²
Fr² = GMm
m = Fr²/GM
Odpowiedź:
a)
P = d/M * RT, M = ? /*M
MP = dRT /:P
P ≠ 0
M = dRT/P
b)
f = 9/5 * c + 32 c = ?
9/5 * c = f - 32 /*5/9
c = 5/9(f - 32)
c)
s = vt + at²/2 a = ?
at²/2 = s - vt /*2/t²
a = 2/t²(s - vt)
d)
F = GMm/r² m = ? /*r²/GM
m = r²F/GM
