Answer:
1.41 × 10⁻⁵Ωm
Explanation:
Resistance of wire is defined by the formula
R = ρL / A
RA / L = ρ
using ohm's law
V = IR
R at 20°C = V / I = 14 / 18.2 = 0.769 ohms
RA / L = ρ
diameter = 0.55 cm = 0.55 / 100 in m = 0.0055 m
A = πr² = 3.142 × (0.0055 m/ 2 )² = 0.0000238 m²
ρ = ( 0.769 ohms × 0.0000238 m²) / 1.30 m = 1.41 × 10⁻⁵Ωm

Answer:
Speed of bike = 2.5 km/h
Distance travel = 1,000 km (Approx.)
Explanation:
Given:
Distance cover by Helmut = 5 km
Time taken = 2 hour
Find:
Speed of bike
Computation:
Speed = Distance / Time
Speed of bike = 5 / 2
Speed of bike = 2.5 km/h
Given:
Speed of plane = 250 km/h
time taken = 3 hr 58 min = 3.967 hr
Find:
Distance travel
Computation:
Distance = Speed x time
Distance travel = 250 x 3.967
Distance travel = 991.669
Distance travel = 1,000 km (Approx.)
Supply of electric charges (electrons) which are free to flow, some form of push to move the charges through the circuit and a pathway to carry the charges.
