Resistance per 1000 feet for gauge 14 wire is given as
R = 2.525 ohm
now if wire is of length 50 feet only then the resistance is given as
now if 11 A current flows through the wire then the voltage drop is given by ohm's law
so most appropriate answer in given options is
A. 1.8 Volts
The average speed is 42.7 m/s
Explanation:
The speed of an object in uniform motion (=moving at constant speed) is given by the equation:
where
v is the speed
d is the distance
t is the time
For the car in this problem, we have:
d = 2560 m (distance)
t = 60 s (time)
Solving the equation, we find the average speed:
