A3.9 g aluminum foil ball with a charge of +4.1Γ10β9 c is suspended on a string in a uniform horizontal eβ field. the string deviates to the right and makes an angle of 30β with the vertical. part a part complete what information about the eβ field can you determine for this situation? what information about the field can you determine for this situation? only the magnitude of eβ only the direction of eβ both the magnitude and the direction of eβ none of the above previous answers correct part b determine the magnitude of the electric field. express your answer with the appropriate units. e e = nothing nothing request answer part c determine the direction of the electric field. determine the direction of the electric field. to the right to the left away from you toward you

This is important 1. what happens to the speed of molecules in water vapor when it condenses to form a liquid? (2 points) the molecules slow down. the molecules speed up. the molecules slow down and then speed up. the molecules speed up and then slow down. 2. how might human activities change to compensate for a decrease in water supplies? (2 points) humans might build a factory. humans might build drainage systems. humans might extract more water from the ground. human behavior does not change because of the water cycle. i'll be grateful if anyone can answer these 2 questions !
