PLEASE HELP! :) Frequency describes the rate in which waves move through a given location. In the simulation, the airplane emits waves
as it travels. The closer together the waves appear, the higher their frequency appears.
Imagine you're standing at the center of the simulation, and the airplane flies directly overhead with an object speed of 50
meters per second. From your perspective, how does the frequency of the waves appear to change as the airplane
approaches and then passes you?

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.
