Answer:
An electric current is a stream of charged particles, such as electrons or ions, moving through an electrical conductor or space. It is measured as the net rate of flow of electric charge through a surface or into a control volume. ... In electric circuits the charge carriers are often electrons moving through a wire.
The angle at which the sunlight received at a location on Earth spread out over the largest area is 10°. Last option is correct.
<h3>What is sunlight?</h3>
The light coming from the Sun reaching the Earth's surface is called as Sunlight.
When the sun is overhead, the intensity is high because sun's rays are perpendicular to the earth's surface, so the energy spreads over a small area and the heat is too high in that region.
When, the angle is smaller, the sunlight will spread out over a larger area.
Thus, at 10° the sunlight received at a location on Earth spread out over the largest area. Last option is correct.

Answer:
The statement that the net magnetic field at the center of this square is zero is false.
The net magnetic field inside a conductor must be zero - This is a true statement
Explanation:
The net magnetic field at the center of this square is not equal to zero.
The net magnetic field at the center of this square is given by the equation below:
B = 2√2μ₀I/πₐ
Where a = the side of the loop, and I is the current.
Thus, the statement that the net magnetic field at the center of this square is zero is false.
The net magnetic field inside a conductor must be zero - This is a true statement because the total charge on the conductor must be equal to zero.
