A motorbike that drives 50 km in 30 minutes is going faster than a car that travels 100 km in 45 minutes. (Remember: 30 minutes = 0.5 hours:
45 minutes = 0.75 hours.)
QUESTION C

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.

truck y has a greater velocity than truck x.

no. bullets are macro objects. wave nature is for light waves, extremely tiny particles. if a light particle was the size of your finger, the bullet would be the size of the universe. so basically, that huge difference in size makes the wave nature of matter insignificant.
