Answer 1

a)

[tex]v = \frac{s}{t} | \times t \\ s = vt[/tex]

b)

[tex]P = mF | \div m \\ F = \frac{P}{m} \\ m \not = 0[/tex]

c)

[tex]E = mgh | \div mg \\ h = \frac{E}{mg} \\ \\ mg \not = 0[/tex]

d)

[tex]K = \frac{a}{R} | \times R \\ a = KR | \div K \\ R = \frac{a}{K} \\ \\ K \not = 0[/tex]

e)

[tex]R = \frac{ax}{b} | \times b \\ ax = Rb | \div a \\ x = \frac{Rb}{a} \\ \\ a \not = [/tex]

f)

[tex]S = \frac{bt}{am} | \times am \\ bt = Sam | \div Sa \\ m = \frac{bt}{Sa} \\ \\ Sa \not = 0[/tex]

g)

[tex]T = \frac{1}{abt} | \times abt \\ 1 = Tabt | \div Tab \\ t = \frac{1}{Tab} \\ \\ Tab \not = 0[/tex]

h)

[tex]v = \frac{ {at}^{2} }{2} | \times 2 \\ {at}^{2} = 2v | \div {t}^{2} \\ a = \frac{2v}{ {t}^{2} } \\ \\ {t}^{2} \not = 0 \\ t \not = 0[/tex]

i)

[tex]R = \frac{abc}{4P} | \times 4P \\ abc = 4RP | \div 4R \\ P = \frac{abc}{4R} \\ \\ 4R \not = 0[/tex]
