a)
[tex]P_{c}[/tex]= [tex]P_{p}[/tex] + [tex]P_{b}[/tex]
---------------------
[tex]P_{p} + P_{b} = P_{c} \\P_{p} = P_{c} - P_{b}[/tex]
---------------------
[tex]P_{p} + P_{b} = P_{c} \\P_{b} = P_{c} - P_{p}[/tex]
b)
P = ah
--------------------
ah = P | : h
a = [tex]\frac{P}{h}[/tex]
-------------------
ah = P | : a
h = [tex]\frac{P}{a}[/tex]
c)
a = [tex]\frac{F}{m}[/tex]
-----------------
[tex]\frac{F}{m} = a[/tex] | *m
F = am
------------------
[tex]\frac{F}{m} = a[/tex]
m = [tex]\frac{F}{a}[/tex]
d)
d = [tex]\frac{m}{V}[/tex]
-----------------
[tex]\frac{m}{V} = d[/tex] | *V
m = dV
----------------
[tex]\frac{m}{V} = d[/tex]
V = [tex]\frac{m}{d}[/tex]
