Asmall compass is held horizontally, the center of its needle a distance of 0.278 m directly north of a long wire that is perpendicular to the earth's surface. when there is no current in the wire, the compass needle points due north, which is the direction of the horizontal component of the earth's magnetic field at that location. this component is parallel to the earth's surface. when the current in the wire is 25.5 a, the needle points 22.3° east of north. what is the magnitude of the horizontal component of the earth's magnetic field at the location of the compass?

battery with hi vtge high val resist in series

when heated, the valance electrons increased their speed and transferred the heat from electron to electron.   i just took the test.

what experimental evidence led scientists to change from the previous model to this one?

a few of the positive particles aimed at a gold foil seemed to bounce back.

the colors of light emitted from heated atoms had very specific energies.

experiments with water vapor showed that elements combine in specific proportions.

cathode rays were bent in the same way whenever a magnet was brought near them.

it is b. absorbs thermal energy
