What is the resultant displacement of a dog looking for its bone in the yard, if the dog first heads 55° north of west for 10.0 m, and then turns and heads west for 5.00 m?

c = 13.5 m

Explanation:

from the attached diagram, we can apply the cosine rule to get the resultant displacement (c) where

c =

         θ + β = 180  (sum of angles on a straight line )

         θ + 55 = 180

         θ = 180 - 55

        θ = 125 degrees

            c =

           c =

           c = 13.5 m

this could be newton#'s law of cooling. the cooling curve is exponential

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.
