In the experiment described in the previous problem the student shortened the coil to a length of 50 cm. a. What is the expected value for the magnitude of the magnetic field inside the coil

(75°f − 32) × 5/9 = 23.889°c

d

explanation:

v=uf/(u-f)

= 5.10/(5-10) convex lens has positive focal length

=50/-5

=-10 cm (formed at other side)

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.
