A small 350 gram ball on the end of a thin, light rod is rotated horizontal circle of radius 1.2 m. Calculate a. the moment of inertia of the ball about the center of the circle and b. the torque needed to keep the ball rotating at constant angular velocity if air resistance exerts a force of 0.020 N on the ball. Ignore air resistance on the rod and it's moment of inertia.​

Sorry i don’t know what to do

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.

Amagnetic field "does not" interact with stationary electric charges. so, a.hope my answer you : )
