Answer:

The answer to your question is: 12.48 s

Explanation:

Data:

initial speed (is) = 12 m/s

final speed (fs) = 13 m/s

distance (d) = 156 m

time (t) = ?

Formula

d = ((fs + is))/2 t        we clear time from this equation    t = 2d / (fs + is)

Substitution             t = 2(156) / (13 + 12)

Process                    t = 312 / 25

                                 t = 12.48 s

Advocard [28]

Answer:

Resistivity ρ=1.12 x 10^-4 Ωm

Explanation:

ρ= RA/l, where R is resistance, A is cross sectional area and l is length

A=πr^2

Note Current is given R is proportion to temperature and inversely proportional to Current R=(20+273)/14*10^-2 =2000Ω

⇒ρ=R*πr^2/l all length in metre.
