One hundred turns of (insulated) copper wire are wrapped around a wooden cylindrical core of cross-sectional area 7.69 × 10-3 m2. The two ends of the wire are connected to a resistor. The total resistance in the circuit is 17.4 Ω. If an externally applied uniform longitudinal magnetic field in the core changes from 2.27 T in one direction to 2.27 T in the opposite direction, how much charge flows through a point in the circuit during the change?

The charge that flows during the change is 0.2C

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.

there are no atoms
