What is the sign of the source charge? negative Now a particle whose charge is -8e-09 C is placed at location A. Which arrow (a-j) best indicates the direction of the electric force on the -8e-09 C charge? c Incorrect: Your answer is incorrect. The electric field at location A has the value < -7000, -7000, 0 > N/C. What is the unit vector in the direction of $ \vec{E} $ at this location? $ \hat{E} = $ What is the electric force on the -8e-09 C charge?

Tafari worked one summer on a ship that set weather buoys in the ocean. he watched how one of the buoys moved in the water. describe which parts of the wave would cause the buoy to bob up and down. which wave property determined how fast the buoys bobbed in the water? he observed that when the wind blew harder, the ocean waves were larger, and the buoys moved away from the ship. what effect, if any, did the waves have on how far the buoys moved? explain your answer.
