As some source continues to recede from you at a constant speed (as in it is already receding beforehand) does the pitch you hear increase, decrease, or remain the same.
Please help thank you

the answer would be   dignified - apex

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.

one person pulls 90n one way and the other has 100n pulling the other way.

so the net force = 90 - 100 = -10n,

or the ans can be 10n if the picture shows -90n and 100n instead.

the answer is 100. i just did this lesson and got a 100% on it. : )
