Katena32 [7]3 years ago
6 0
The ratio of surface area to volume is the amount of surface area per unit volume of a thing. This is an important value in various topics. In chemistry, this is an important value for chemical reactions. It can show reactivity of a solid material. Also, it has found some importance in biology because it shows how the cells are affected by the environment where that cell is found.<span />

I know it seems that alot of people like on here so people do their work but I really need help!!! I have a set of problems that
marshall27 [118]

Answer:

No Problem, I know That I personally can't stand it when people just give me the number. So another way to think of this problem is "How many 2/3 are in 3 cups." So try drawing 3 rectangles to represent 3 cups and then draw two lines inside those rectangles so that there are 3 rectangles inside each one and then shade in two of the smaller rectangles in a way that you can tell them all apart preferably different colors and then just count them.

Step-by-step explanation:

Hope this is enough to help you understand it, if not then feel free to ask for more info in the comments. :)

Given a mean earth radius of 20,906,000 ft, and an observation latitude of n 42 degrees, what is the arc distance of one second
murzikaleks [220]

Answer:

  • arc second of longitude: 75.322 ft
  • arc second of latitude: 101.355 ft

Explanation:

The circumference of the earth at the given radius is ...

  2π(20,906,000 ft) ≈ 131,356,272 ft

If that circumference represents 360°, as it does for latitude, then we can find the length of an arc-second by dividing by the number of arc-seconds in 360°. That number is ...

  (360°/circle)×(60 min/°)×(60 sec/min) = 1,296,000 sec/circle

Then one arc-second is

  (131,356,272 ft/circle)/(1,296,000 sec/circle) = 101.355 ft/arc-second

__

Each degree of latitude has the same spacing as every other degree of latitude everywhere. So, this distance is the length of one arc-second of latitude: 101.355 ft.

_____

<em>Comment on these distance measures</em>

We consider the Earth to have a spherical shape for this problem. It is worth noting that the measure of one degree of latitude is almost exactly 1 nautical mile--an easy relationship to remember.
