5. A 12kg box of fruit needs to be moved to the other side of the warehouse. (a) Calculate the minimum force required to get the box moving if us = 0.47? (b) If the force from (a) is constant and continues to push the box,
how fast will the box accelerate if uk = 0.33?

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.

force tends to be low and long diustance masses are high
