a physics teacher is walking on a sidewalk at a constant velocity toward a building with a two story window where a group of young physics students are gathered. the students make some calculations to determine if a water balloon dropped at a certain time will hit the teachers head. the teacher is 1.5 meters tall and will reach the window area in 1.8 seconds from the time of the drop. if the balloon is dropped from a height of 9 meters, will the water balloon hit the physics teacher?

Apositive charge moves in the direction of an electric field. which of the following statements are true? check all that apply. check all that apply. 1.the potential energy associated with the charge decreases. 2. the electric field does positive work on the charge. 3. the electric field does negative work on the charge. 4. the potential energy associated with the charge increases. 5. the electric field does not do any work on the charge. 6. the amount of work done on the charge cannot be determined without additional information.
