The inductive reactance of the circuit is exactly twice the resistance: xl=2r. adjust the phasor that represents the voltage across the inductor (vl) at the instant indicated to the proper length and orientation.

∅=

Explanation:

z=impedance

=2R

R=R

The resultant of the resistances in the circuit is called impedance

is inductive reactance of the circuit

R is the resistance of the resistor

z=

z=

Z=

Z=Rohms

tan∅=2R/R

tan∅=2

∅=Tan^-1(2)

∅=

phase angle is ∅=

Answer: it will take   4.36 seconds to reach her average velocity 10.69 miles/hour.explanation:   we have equation of motion ,where s is the displacement, a is the acceleration, u is the initial velocity and t is the time taken.average velocity = displacement/ time taken.average velocity = 10.69 miles/hr = 10.69*1.6*1000/(60*60) = 4.75 m/s4.75 = s/ts = 4. 1we also have acceleration = 2.18 m/s², initial velocity = 0 m/sso it will take   4.36 seconds to reach her average velocity 10.69 miles/hour.
