The magnetic field due to a 2-a current flowing in a long, straight wire is 8 μt at a point p, a certain distance away from the wire. how far is this point from the center of the wire?

Distance from the center of wire is 0.05 meters.

Explanation:

It is given that,

Current flowing in the wire, I = 2 A

Magnetic field,

Let d is the distance from the center of the wire. The magnetic field at a distance d from the wire is given by :

d = 0.05 meters

So, the distance from the wire is 0.05 meters. Hence, this is the required solution.

here are some information of the future of geothermal energy:

-the future of geothermal energy can pretty much be summed up with a single word: more

-scientists plan in going deeper than 120 meters

-we are hoping that one day, we will get all of our energy from renewable energy sources such as geothermal energy

hope this !
