The magnetic flux that passes through one turn of a 12-turn coil of wire changes to 5.50 from 9.11 wb in a time of 0.0309 s. the average induced current in the coil is 272 a. what is the resistance of the wire?

The resistance of the wire is 5.15 ohm

Explanation:

Given Magnet flux change through one turn is

Time take

Induced current

Number of turns ,N= 12 turns

Therefore total change in flux through 12 turns is

Now induced voltage in the coil is given by

where R = Resistance of the wire

=>

Thus the resistance of the wire is 5.15 ohm

they are non-matter

explanation:

they are non-matter. basically, any type of energy or any abstract concept is an example of something that does not matter. other examples include dreams, magnetism, radio, and hate

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.
