Primitive transportation and storage systems that make local distribution ineffective if not impossible, and the lack of clean water and the lack of effective sewer systems are all examples of the barrier called physical & environmental barriers.
What are the problems with having physical & environmental barriers?
Time, Place, Space, Climate, and Noise are the key environmental/physical constraints. Some are simple to change, while others may prove to be difficult.
Physical barriers are essentially defined by three primary factors: environment, distance, and medium unawareness. Environmental barriers, on the other hand, are connected to variables that occur in the current environment.

for the highest thermal stability, a refrigerator freezer compartment should be fully packed with food. what is the thermochemical basis for this recommendation?
The thermal stability depends on the heat capacity and the heat capacity depends on the mass. When the food is fully packed the mass increases due to which the heat capacity increases. By increasing heat capacity, the thermal stability increases and hence effective working of freezer takes place.

Why would you consider hibernating an EC2 instance over stopping and
starting it?
Answer:
Why does stopping and starting an instance (usually) fix a System Status Check error? Stopping and starting an instance causes the instance to be provisioned on different AWS hardware.
Explanation:
Image result for Why would you consider hibernating an EC2 instance over stopping and starting it?
When you stop and start your instance, you lose any data on the instance store volumes on the previous host computer. Your instance retains its private IPv4 address, which means that an Elastic IP address associated with the private IPv4 address or network interface is still associated with your instance.

if there are 250 grains per square inch on a photomicrograph of a ceramic material at 200x, what is the astm grain-size number of the material? (15 points)
The astm grain-size number of the given material is; 10.97
What is the Grain Size number of the material?Grain size is defined as the dimensions of grains or crystals in a polycrystalline metal that is exclusive of twinned regions and subregions that are present.
The equation for the grain size number is expressed as;
N(M/100)² = 2⁽ⁿ ⁻ ¹⁾
where;
N = number of grains per square inch at magnification M.
M = Magnification
n = ASTM grain size number
We are given;
N = 250 grains per square inch
M = 200
Thus;
250(200/100)² = 2⁽ⁿ ⁻ ¹⁾
250 * 2² = 2⁽ⁿ ⁻ ¹⁾
1000 = 2⁽ⁿ ⁻ ¹⁾
log 1000 = nlog 2 - log 2
n = [(log 1000) + (log 2)]/log 2
n = (3 + 0.301)/0.301
n = 10.97

Measure and record your height in feet and inches and then convert your height to meters and then to centimeters. Feet-inches: ________________ Meters: _________________ Centimeters: ________________
Answer:
See explanation.
Explanation:
Since I don't want to share identifiable information on the internet, instead of using my real height I will use 5 ft 10 inches.
Step 1: convert ft to inches
[tex]5ft*\frac{12 in}{1ft} =60 in[/tex]
Total height: 60+10 in = 70 in
Step 2: convert in to cm
[tex]70 in\frac{2.54cm}{1 in} =177.8cm[/tex]
Height: 177.8cm
Step 3: convert cm to m
[tex]177.8 cm*\frac{1m}{100 cm} =1.778 m[/tex]
Summary: 5ft 10 in = 70 in = 177.8 cm = 1.778 m
