An asteroid is seen traveling directly toward Earth. It's velocity is 7.8500 x 102 m/s when it's 2.0000 x 106 m away from the surface of the Earth. How fast will the asteroid be moving when it collides with the surface of Earth? Assume that the radius of the Earth is 6.3570 x 106 m and the mass of Earth is 5.9720 x 1024 kg. Ignore any effects from air resistance

ok

explanation:

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.

find the surface area of the sphere to the nearest square unit. use a calculator.

a. 254 in.2

b. 64 in.2

c. 127 in.2

d. 1,018 in.2

the answer is c. the lower legs are levers, and the knees are fulcrums. the ankles hold the loads.
