A concrete pile from a waterfront pier was pulled from the harbor water at port hueneme california. It's dimensions we're 14in x
Anna [14]

The surface area expressed in square feet of a single face of a pile is 1.45 square feet.

<u>Explanation:</u>

The dimensions of the pillar are given as 14 in \times 14 in

(1 feet = 12 inch)

According to the pillar dimensions mentioned in the problem, the length of the pillar should be 15 inches, height by 14 inches and the width by 14 inches.

There will be two surface areas of the concrete pile, one implies side surface area and the other is end surface area.

For calculating the side surface area,

Area of the side surface = 14 in \times 15 in

                                         = 14 in. \times  \frac{1 ft.}{12 in.}

                                         = 1.16 \times 1.25

                                         = 1.45 square feet.

(In the given question, only a single face is asked so there is no need to find the surface area of the end face.)

Explain what happens to the energy in a wave when a sound is louder.
liraira [26]
Greater amplitude waves have more energy and greater intensity, so they sound louder. ... The same amount of energy is spread over a greater area, so the intensity and loudness of the sound is less. This explains why even loud sounds fade away as you move farther from the source.

8.8 Why do esters with higher molecular mass not have strong fragrances?​
Lerok [7]

Answer:

Basically, fragrances reach other person through sense of smell. So, the strength of the fragrances depends a lot on its evaporation, which is strongly related to the boiling point. Esters with higher molecular weight do not have a strong fragrance because it has a higher boiling point.

Chemical Reactions
irakobra [83]

Answer:

It works by separating the fuel from the oxygen. The oxygen comes from the air. It is the same oxygen we breathe. Since the oxygen has to be in contact with the fuel, if you can coat the fuel with something that keeps the oxygen away, the fire will go out which is what the fire extinguisher does.
