2 answers:
Answer:
Explanation:
We want to find the distance the jet travels. Distance can be found by multiplying the speed by the time.
The speed is 100 meters per second.
The time is 10 seconds.
Substitute the values into the formula.
Multiply. Note that the seconds, or "s" will cancel each other out.
The jet travels <u>1,000 meters</u> before taking off.

Explanation:
From the question we are told that
The inner radius is
The outer radius is
The nu umber of turns is
The current it is carrying is
Generally the magnetic field is mathematically represented as
Where is the permeability of free space with a constant value
And the given distance where the magnetic field is felt is r = 0.9 cm = 0.009 m
Now substituting values
Fro the second question the distance of the position considered from the center is r = 1.2 cm = 0.012 m
So the magnetic field is
