11 Dinah rolled a lobster up a ramp. At the base of the ramp the lobster had 440 J of kinetic energy. How much potential energy did the lobster have at the peak of its roll?

this a false

explanation:

potential energy is directly proportional to height.

more height = more potential energy.

greatest increase in height = greatest increase in potential energy

where are the points with the greatest increase in height ?

has to be c-e or d-e .

pe = weightxheight = 2000x1000=2,000,000joules

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.
