Which answer choice is correct about the pictures?
Student 1: The lightning does not belong in the group because it uses human-harnessed energy for electricity. It does not utilize naturally-occurring electricity.
Student 2: The image of the sock does not belong because it is clinging to the clothes due to static electricity, while all of the other images are examples of current electricity.
Student 3: The image of the electrical outlet does not belong because it is the only example of human-harnessed electricity.
Student 4: The image of the sock does not belong because the dryer created the cling, and since humans use electricity to power dryers it is an example of human-harnessed electricity.

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

Two conductors, a and b, are each in the shape of a tetrahedron. but of different sizes. they are charged in the following manner: 1. tetrahedron a is charged from an electrostatic generator to charge q. 2. tetrahedron a is briefly touched to tetrahedron b. 3. steps 1 and 2 are repeated until the charge on tetrahedron b reaches a maximum value. if the charge on tetrahedron b was q/4 after the first time it touched tetrahedron a. what is the final charge qbmax on tetrahedron b?
