Answer:
Explanation:
impedance z=(XL^2+R^2)^1/2
power across te resistor ==i^2r
286/300
I=.976
Except when necessary for takeoff and landing, <span>the minimum safe altitude required for a pilot to operate an aircraft over other than congested area is an altitude of 1000 ft above the highest obstacle within a 2000 ft horizontal radius of the aircraft.
It is also good to know that apart from taking off and landing, the aircraft must not operate at a distance less than 500 ft from any person, vessel, structure or vehicle.</span>
Time period = 1 / frequency
Time period = 1 / 250 th of a second
