You are a middle school principal in a working-class conservative community in the Midwest. One of your tenured teachers placed a series of very negative comments about you and the school on her Facebook page. These comments were made over the weekend. A number of your students informed you that they read the teacher’s comments. In fact, you heard a group of students chatting and laughing about the comments. Additionally, you receive phone calls from a number of parents who conveyed how negative and unprofessional the teacher’s comments were.

If evidence reveals that the teacher is responsible for these comments, what action would you take?

What options are available to you in addressing this situation?

What precautions must be taken to ensure that the teacher’s rights are protected?

How do you balance the rights of the teacher against the need to protect the integrity of the school?

Please discuss the probable consequences of each option you identified.

What is your final decision? Provide a rationale for your decision.

A square section wire of side L is traversed by a current I in the +z direction. The wire is embedded in a constant magnetic field B in the +y direction. You measure a voltage V across L in the horizontal direction. Find the number density of electrons in the metal and identify the direction of the electric field inside the wire.

Hydrogen also produces spectral lines at radio wavelengths, notably at 21.1 cm. If a galaxy is moving away from us at 21% of the speed of light, at what wavelength will we detect this line? Convert this into frequency.

We will detect this line at wavelength λ = ______ cm.

The frequency is v = _____ × 10^9 Hz or ______ GHz.
