Explanation:
It is given that,
Current carried in the conductor, I = 14.7 A (+x axis)
The magnetic force per unit length on the conductor, 
(-y axis)
The magnetic force is given by :
B = 0.0085 T
According to right hand rule, the direction of magnetic force can be calculated. So, the direction of magnetic field is along +z axis. Hence, this is the required solution.
Answer: 1500metres
Explanation: the formula for distance is speed × time which equals 150m/min × 10 min = 1500m
This formula can be rearranged...
Speed = Distance ÷ time.
Time= Distance ÷ speed.
Distance= Time × speed.

Answer:
<h3>After 3seconds</h3>
Explanation:
A supersonic aircraft flies at 3 km altitude at a speed of 1000 m/s on a standard day. How long after passing directly above a ground observer is the sound of the aircraft heard by the ground observer
Using the formula for calculating speed expressed as;
Speed = Distance/Time
Given;
Distance = 3km = 3000m
Speed = 1000m/s
Required
How long after passing directly above a ground observer is the sound of the aircraft heard by the ground observer (Time)
From the formula;
Time = Distance/speed
Time = 3000/1000
Time = 3seconds
Hence the sound of the aircraft is heard after 3 seconds
