To solve this problem we will use the Ampere-Maxwell law, which describes the magnetic fields that result from a transmitter wire or loop in electromagnetic surveys. According to Ampere-Maxwell law:
Where,
B= Magnetic Field
l = length
= Vacuum permeability
= Vacuum permittivity
Since the change in length (dl) by which the magnetic field moves is equivalent to the perimeter of the circumference and that the electric flow is the rate of change of the electric field by the area, we have to
Recall that the speed of light is equivalent to
Then replacing,
Our values are given as
Replacing we have,
Therefore the magnetic field around this circular area is
Answer:
Gravity and force can be applied with it.
Explanation:
A. Synthesis, decomposition, single-replacement, combustion
If there are two forces acting on a rocket, and the forces are equal and opposite, then they add up to zero, and there is no NET force at all on the rocket.
Then the rocket can only move at a constant speed in a straight line. It can't have any acceleration (change of speed or direction.)
