figure 1 above shows a car moving towards C, with a constant velocity of 30ms-1. As the car passes A, the driver sees an obstruction in the road at C. Due to reaction time of the driver, the car travels a distanc of 27m at the same velocity

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.
