Answer D. The pitch is in the frequency.
A decagram is 1000 times bigger than a centigram
This is honestly not something I’ve learned. The answer is something I don’t know.
Answer:
250 A
Explanation:
B = 5 x 10^-5 T, r = 1 m
Let current be i.
the magnetic field due to a straight current carrying conductor is given by
B = μ0 / 4π x 2i / r
5 x 10^-5 = 10^-7 x 2 x i / 1
i = 250 A
