What is the average electric current in a wire when a charge of 150 C passes in 30 s?

Which graph best represents the relationship between the electric current and the rate at which a magnet is turning inside an electric generator?

How is the gravitational force related to the distance between two objects?

Although longitudinal waves can travel through all media types what is the disadvantage of this type of wave transmission? a) he efficiency of he wave transmission is greatly diminished as the media becomes less dense b) the oscillation of one set of particles has a huge impact on neighboring particles c) particles become too close together as they bump into each other making it more likely to hit other particles down the line
