Your boss asks you to design a room that can be as soundproof as possible and provides you with three samples of material. the only information on each sample's label is the material's coefficient of absorption. the coefficient of absorption listed on sample a is 30%, on sample b is 47%, and on sample c is 62%. when your boss asks for your choice and the reasoning behind it, what would you tell him?
a. sample c would be best, because the percentage of the energy in an incident wave that remains in a reflected wave from this material is the largest.
b. sample a would be best, because the percentage of the energy in an incident wave that remains in a reflected wave from this material is the largest.
c. sample c would be best, because the percentage of the energy in an incident wave that remains in a reflected wave from this material is the smallest.
d. sample a would be best, because the percentage of the energy in an incident wave that remains in a reflected wave from this material is the smallest.

In this particular instance, the best sample to use would be C. The specific reasoning behind this would be letter D, in that the reason sample C would work best is due to the fact that the percentage of the energy in an incident wave that remains in a reflected wave from this material would be the largest. This would therefore lead to the greatest possible amount of sound-proofing within the materials provided.

Grilled ham and cheese sandwich: caution: if you’re underaged then have a responsible adult supervising you to prevent any injuries.1. preheat a pan or griddle over medium heat. spread each bread slice with mustard — crust to crust is a must to get full coverage so that each bite is identical. if you don’t like mustard then use whatever else you like.2. use a trio of cheeses in a grilled cheese to achieve perfect harmony: 1 slice of american cheese for gooeyness, 1 slice of aged cheddar for sharpness and 1 slice of provolone or mozzarella for stringiness. if you don’t like these cheeses then use whatever else you like.3. ribbon your meat onto your sandwich to create dramatic height and a smoother bite down. don't just lay the meat flat — it makes for a flat sandwich.4. add anything else you'd like to the sandwich — (just make sure you season them with a bit of salt and 5. spread mayo on the outside of a grilled cheese before it goes into the pan or onto the griddle, which ensures that it will be perfectly golden brown every time.6. place on the griddle; dome your grilled cheese with a metal bowl to create a vortex of heat and ensure the cheese melts without over-toasting the exterior for a maximum of 3 minutes. flip, cover again and cook until the cheese is melted and the sandwiches are golden brown for a maximum of 3 minutes. hope this : )
