Here is a graph showing how the force on an object changes over time. If the object started from rest, what is its momentum after 5 seconds? -8 kg*m/s
-6 kg*m/s
-0 kg*m/s
-2 kg*m/s

    5.5 n======    assuming that      we have      m = 0.145 kg    a = 38 m/s²therefore    5.51 n, but two significant figures.final answer: 5.5 n

The answer is water molecules are split.cellular respiration and photosynthesis are complement  reactions to each other. these are reverse reactions. in cellular respiration glucose and oxygen yield water and carbon dioxide. so, when respiration begins,  glucose molecules are split. in the opposite reaction - in photosynthesis, carbon dioxide and water yield glucose and oxygen. thus,  when respiration begins, water molecules are split.

The answer is trial 3.

Because the sun is the biggest and if the sun orbits the earth we will be dead probably
