Driving in your car with a constant speed v v
, you encounter a bump in the road that has a circular cross section, as indicated in the figure(Figure 1). The radius of curvature of the bump is 35 m.

At what speed must you go over the bump if people in your car are to feel "weightless"?

explanation:

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.
