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
Answer:
2 m/s and -2 m/s
Explanation:
The object travels with an angle of
60.0°
with the positive direction of the y-axis: this means that it lies either in the 1st quadrant (positive x) or in the 2nd quadrant (negative x).
If it lies in the 1st quadrant, the value of vx (component of v along x direction) is:
If it lies in the 2nd quadrant, the value of vx (component of v along x direction) is:
