Assume that the ground temperature Tg is 40 F (10 C) and that the inside temperature of the basement is 68 F (20 C) for Problem 3. Estimate the temperature between the wall and insulation, T2 and between the gypsum board and insulation T1. Answer: T1 = 64.3 F; T2 = 49.36 F
At high temperatures, there is a large amount of radiative heat transfer via the fibre insulation employed in thermal protection systems (TPS) (1200 C).
At high temperatures, fibre insulation used in thermal protection systems (TPS) radiatively transfers a substantial amount of heat (1200 C). The TPS's ability to insulate can therefore be significantly affected by reducing the radiative heat transfer through the fibre insulation. Directly applying reflective coatings to the individual fibres of a fibrous insulation should reduce radiative heat transfer, resulting in a less effective thermally conductive insulation. Sol-gel processes have been used to create coatings with high infrared reflectivity. By using this method, fibre insulation can receive uniform coatings without noticeably increasing its weight or density. To assess coating performance, ellipsometry, scanning electron microscopy, and Fourier Transform infrared spectroscopy have all been used.

T/F a weakness of a signature-based system is that it must keep state information on a possible attack.
Answer:
True
Explanation:
Determine the force in members CD, CF, and CG and state if these members are in tension or compression.
The force of given members in tension or compression are CD = 11.25 = 11.2 kN (C), CF = 3.21 kN (T), CG = 6.80 kN (C)
Rope bridges can support both themselves and the load they carry because tension forces cause material to be pulled and stretched in opposing directions. The rocks of an arch bridge press against one other to carry the weight because compression forces squeeze and push material inward. The bottom beam fiber tends to stretch when subjected to a normal vertical live load, whereas the top beam fiber tends to compress (tension). Comparatively speaking, the corresponding truss's bottom chord is under tension and its top chord is in compression. When two or more physical objects come into contact, they apply forces to one another. We label these contact forces differently depending on the objects that are in contact.

Agile approaches are the foundation of the backlog idea. Many teams continually prioritize what to build and when using adaptive planning strategies. Even teams that do not strictly adhere to the agile methodology now frequently use backlogs to organize and prioritise work items.

On mountain roads, if you have ____ or more vehicles behind you, you must use turnouts to let them pass.
On mountain roads, if you have __5__ or more vehicles behind you, you must use turnouts to let them pass.
Before passing a bus or truck, be sure you can see the driver in the side mirror. To safely and quickly pass the truck or bus, signal loudly, then move into the left lane and speed up. Stay out of the blind spot. In order to observe any items through the rear view glass on the right side and rear of the car, you should be backing up with your head pointed toward the right rear of your vehicle. Driving on two-way streets is simpler since you can readily observe the approaching cars. Never cross the centerline when you get close to a hill's top.

To alter the program so that a valid password consists of 10 charac- ters, 6 of which must be digits and the other 4 letters.
What is password?A password is a group of characters used to verify a user's identity on a computer system. You might, for instance, need to log in to a computer account. You must enter a true username and password in order to access your account. The term "login" is frequently used to describe this combination. Passwords are private to each user, whereas usernames are typically public knowledge.
Most passwords are made up of a number of characters, which can typically include letters, numbers, and the majority of symbols but not spaces. While picking a password that is simple to remember is a good idea, you shouldn't make it so straightforward that anyone can figure it out.

Currency Exchange Programming challenge description: Given A list of foreign exchange rates A selected curreny A target currency Your goal is to calculate the max amount of the target currency to 1 unit of the selected currency through the FX transactions. Assume all transations are free and done immediately If you cannot finish the exchange, return Input: You will be provided a list of fx rates, a selected currency, and a target currency. For example: FX rates list: USD to JPY 1 to 109 USD to GBP 1 to 0.71 GBP to JPY 1 to 155 Original currency: USD Target currency : OPY Output: Calculated the max target currency will can get. For example: USD to JPY -> 109 USD to GBP to JPY = 0.71 . 155 = 110.05 > 109. so the max value will be 110.05 Test 1 Test Input USD, GBP, 0.7;USD, JPY, 109;GBP, JPY, 155; CAD, CNY, 5.27; CAD, KRW, 921 USD CNY USD to GBP 1 to 0.71 GBP to JPY 1 to 155 Original currency: USD Target currency : JPY Output: Calculated the max target currency will can get. For example: USD to JPY -> 109 USD to GBP to JPY = 0.71 155 = 110.05 > 109, so the max value will be 110.95 Test 1 Test Input USD, GBP, 0.7;USD, JPY, 109; GBP, JPY, 155; CAD, CNY,5.27;CAD, KRW, 921 USD CNY Expected Output -1.2 Test 2 Test Input USD, CAD, 1.3;USD, GBP, 0.71; USD, JPY, 109;GBP, JPY, 155 USD JPY Expected Output 110.05 1 import sys 2 for line in sys.stdin: print(line, end="") 3
The Currency Exchange Programming for max amount of the target currency to 1 unit of the selected currency can be written using python.
The programming code in python is,
#The given code start
import sys
for line in sys.stdin:
print(line, end="")
#The given code end
break
list_foreign_exchange = line.strip()
selected_currency = ""
target_currency = ""
found = False
max1 = 0
for line in sys.stdin:
print(line, end="")
if list_foreign_exchange == "":
list_foreign_exchange = line.strip()
elif selected_currency == "":
selected_currency = line.strip()
else:
target_currency = line.strip()
break
if selected_currency == target_currency:
print("0")
else:
currency = []
currency_string = list_foreign_exchange.split(";")
for cur in currency_string:
currency.append(cur.split(","))
for cur in currency:
if (selected_currency == cur[0]) and (target_currency == cur[1]):
max1 = float(cur[2])
found = True
break
max2 = 1
tried_index = 0
ref = selected_currency
for cur in currency:
if ref == cur[0]:
ref = cur[1]
max2 *= float(cur[2])
if cur[1] == target_currency:
found = True
break
if found == True:
if (max2 > max1):
print(max2)
else:
print(max1)
else:
print('-1.0')
In the code above, we use loop statement to iterate each currency and IF-ELSE function to check the each condition, so we can get the result exactly to the goal.

problem 8.54 for each of the following pairs of polymers, do the following: (1) state whether it is possible to decide whether one polymer has a higher tensile strength than the other; (2) if this is possible, note which has the higher tensile strength and cite the reason(s) for your choice; and (3) if it is not possible to decide, state why. (a) linear and isotactic poly(vinyl chloride) with a weight-average molecular weight of 100,000 g/mol; branched and atactic poly(vinyl chloride) having a weight-average molecular weight of 75,000 g/mol (b) graft acrylonitrile-butadiene copolymer with 10% of possible sites crosslinked; alternating acrylonitrile- butadiene copolymer with 5% of possible sites crosslinked (c) network polyester; lightly branched polytetrafluoroethylene
Possible, tensile strength increases with molecular weight. Therefore the linear and isotactic polymer will have the higher tensile strength.
What is about pairs of polymers?Possible, tensile strength increases with molecular weight. Therefore the linear and isotactic polymer will have the higher tensile strength.
1) Possible, With an increase in molecular weight, tensile strength rises. As a result, polymers that are linear and isotactic will have a greater tensile strength.
2) It seems unlikely that both polymers display the same level of enhanced tensile strength, but we lack sufficient data to determine how much is raised and which polymer exhibits a greater value.
3) Due to a higher number of covalent bonds, network polymers may, in general, have higher tensile strengths than branch structures.
