Bees develop a positive charge as they fly through the air. when a bee lands on a flower, charge is transferred, and an opposite charge is induced in the earth below the flower. the flower and the ground together make a capacitor; a typical value is 0.60 pf. if a flower is charged to 30 v relative to the ground, a bee can reliably detect the added charge and then avoids the flower in favor of flowers that have not been recently visited. approximately how much charge must a bee transfer to the flower to create a 30 v potential difference?

Find v(t), given acceleration a(t)=7j and initial velocity v(0)=k
