A parachute on a racing dragster opens and changes the speed of the car from 85 m/s to 45 m/s in a period of 0.1 minute. What is the acceleration of the dragster?

the current is 0.6

voltage ÷ resistance = current

so 12 ÷ 20 = 0.6

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.

technology is the application of the knowledge gained by science.
