• Newton’s third law can also be phrased in terms of momentum: for any closed system of objects, the total momentum remains . Note that momentum can be exchanged between two objects in a closed system. However, the change in momentum for one object must be to change in momentum of the other object. • Fill in the appropriate units for each quantity: momentum: impulse:

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.

the answer is the index of refraction of the second medium is higher. i just took the test.

98.4 m

explanation:

let s = distance up the plane  

then by conservation of energy  

1/2m(18.3)^2 = mg s sin(10)  

(18.3)^2 = 2g s sin(10)  

s = (18.3)^2/2gsin(10)  

= 98.39564526  

= 98.4 m
