A200 kg satellite is lifted an orbit of 2.2*10power4 km radius. if the radius and mass of earth are 6.37*10mpower6 and 5.98*10 power24kgand find additional p. e to required lift the satellite?

    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.

Velocity is the speed of an object in a certain direction so you'd need to know speed and direction
