The correct option is C.
In physics, the gravitational law makes us to understand that gravity change with altitude. The higher the altitude, the more the gravity one will experiences. Change in altitude also produce change in weight but all these changes are not really significant. Therefore, there will be no significant difference between weighing metals at different altitude, this is because the effect of gravity on them will be the same.

It increases the precipitation in North America.
Answer:
C) must be such as to follow the magnetic field lines.
Explanation:
Ampere's circuital law helps us to calculate magnetic field due to a current carrying conductor. Magnetic field due to a current forms closed loop around the current . If a net current of value I creates a magnetic field B around it , the line integral of magnetic field around a closed path becomes equal to μ₀ times the net current . It is Ampere's circuital law . There may be more than one current passing through the area enclosed by closed curve . In that case we will take net current by adding or subtracting them according to their direction.
It is expressed as follows
∫ B.dl = μ₀ I . Here integration is carried over closed path . It may not be circular in shape. The limit of this integration must follow magnetic field lines.
the term ∫ B.dl is called line integral of magnetic field.
The forces on one of the wires will be 0.000264 N.It is the field sensed around a moving electric charge that gives rise to the magnetic force.
<h3>What is a magnetic field?</h3>
It is the type of field where the magnetic force is obtained. With the help of a magnetic field. The magnetic force is obtained it is the field felt around a moving electric charge.
The given data in the problem is;
I is the current = 6.50 A
B is the magnetic field=f 2.71 X 10⁻⁵ T
The force on the wire is;
Hence, the force on one of the wires will be 0.000264 N.
