Definition: This is what causes acceleration. Two forces acting opposite each other.
Example: Ben pushes on a heavy box. Friction opposes Ben's push. The box moves. Ben's pushing force is
greater than the friction force.

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.

i really dont know but i will try okay.

so i think u would just add all them up and get your answer..

distance = 150m

displ = root (50 ^2 + 100^2)

root(2500+10000)

root 125000
