Answer:
I = 3.82 x 10^(−7) A
Explanation:
The formula for magnetic field at the centre of a loop is given as;
B = μI/2R
Where μ is a magnetic constant with a value of 12.57 × 10^(−7) H/m.
I = current
R = Radius = 16/2 = 8cm or 0.08m
B = 3.0×10^(−12) T
So making I the subject of the formula, we obtain ;
I = 2RB/μ
Thus, I = [2 x 0.08 x 3.0×10^(−12)]/12.57 × 10^(−7)
I = 3.82 x 10^(−7) A
Answer:
Explanation:
Hello.
In this case, since the velocity is computed via the division of the distance traveled by the elapsed time:
The distance is clearly 1743 km and the time is:
Thus, the velocity turns out:
Which is a typical velocity for a plane to allow it be stable when flying.
Best regards.
