The answer to your question 25.333333333
we are given in the problem the following dimensions or specifications
B = 0.000055 T r = 0.25 m constant mu0 = 4*pi*10-7
The formula that is applicable from physics is
B = mu0*I/(2*pi*r) I = 2*B*pi*r/mu0 I = 68.75 Amperes
Answer:
Weight
Weight ( ) is a force, measured in newtons ( ). Weight is caused by the pull of gravity acting on a mass, usually near the surface of a planet.
Explanation:
B. because the heavier an object the stronger the gravitational pull is
