Answer:
False
Explanation:
The direction of magnetic field on a current carrying conductor can be determined by the Fleming's right hand rule where
- The thumb represents the direction of motion
- the index finger represents the direction of field.
- The middle finger is the direction of induced current.
When two conductors carrying currents flowing in opposite direction, the magnetic field will be in the same direction hence they will repel.
<u><em>When the currents in them flow in same direction, then it means the magnetic field will be opposition and there will be a force of attraction between the conductors.</em></u>
The point is the water table closest to the surface in valleys.
In areas of topographic relief, the water table generally follows the surface but tends to approach it in valleys and intersect the surface with streams and lakes. Closest to the surface is the vented zone where the interstices between the soil are filled with both air and water. Below this layer is a saturation zone where the gaps are filled with water.
The water table is the subsurface boundary between the soil surface and the area where groundwater saturates the space between sediment and rock fissures. At this boundary, water pressure equals atmospheric pressure. The top surface of the groundwater is the groundwater table. Beneath this surface, all pore spaces and cracks in sediments and rocks are completely filled and saturated with water. Groundwater occurs in these saturated layers known as saturation zones or water vapor zones.

For a point charge, how does the potential vary with distance from the point charge, r?
a constant
b. r.
c. 1/r.
d. 
.
e. 
.
Answer:
The correct option is C
Explanation:
Generally for a point charge the electric potential is mathematically represented as
Here we can deduce that the electric potential varies inversely with the distance i.e
So

Cleaning tools, equipment, supplies, and materials that can be easily found in a school in one each are: scrub brush, sponges, buckets and brooms.
These equipments are essential to promote a clean, organized and safe environment and for this reason, they can be easily found both at school and in a home, since the cleanliness of these two places is essential for the well-being, proactivity and health of the people who attend them.
Answer:
I = 0.44 A
Explanation:
The magnetic force on a conductor is given by the expression
F = I L x B
Where bold letters indicate vectors, I is the current, L is the vector in the direction of the current, and B is the magnetic field
Since the force is maximum, the wire must be perpendicular to the magnetic field, therefore
F = I L B sin 90
I = F / L B
Let's calculate
I = 1.2 / 1.5 1.8
I = 0.44 A
