Since they both have the same momentum, the object with the larger mass has a small velocity. (Remember that mass and velocity are inversely proportional with
p=mv.) Therefore, the smaller object will have the larger KE. (KE = 1/2 ^2)
The answer is A. Energy first enters an ecosystem through light energy that is absorbed through photo-synthesizers

It has the electron configuration of Kr, plus filled 5s and 4d subshells.
Thus, its electron configuration is
1s² 2s²2p⁶ 3s²3p⁶ 4s²3d¹⁰4p⁶ 5s²4d¹⁰
