A plane metal shield offers an absorption loss of 30 dB at a frequency of
10 kHz to normally incident radiated emission.

(a) Determine the absorption loss at 10 kHz in a shield of five times the
thickness.

(b) Determine the absorption loss at 20 kHz in a shield of half the
original thickness.

Describe the movement of electrons required to develop electrical current.

Think about your energy intake today. Pick one food and identify the chain of energy that led to it. What trophic level do you eat from most? Where will the energy that you ingest eventually wind up?

Why do people mistake what is in diet energy drinks for actual energy?

If you went into a disaster shelter, could you get cell phone service inside? What kinds of electromagnetic radiation could this shelter protect you from? For example, does light pass through the shelter, get absorbed by the shelter, is it reflected by the shelter or does light interact with the shelter in a variety of ways?
Research and report on the following properties of all elements on the periodic table in Group IIA: physical properties of each element (color, texture, mass) and chemical properties of the elements (density, crystal shape, etc.).
