A liquid-to-liquid heat exchanger uses a heat-transfer fluid that circulates through the solar collector, absorbs heat, and then flows through a heat exchanger to transfer its heat to water in a storage tank. Heat-transfer fluids, such as antifreeze, protect the solar collector from freezing in cold weather.
Answer:
def str_analysis(s):
if s.isdigit():
s = int(s)
if s > 99:
message = str(s) + " is a pretty big number"
else:
message = str(s) + " is a smaller number than expected"
elif s.isalpha():
message = s + " is all alphabetical characters!"
else:
message = "There are multiple character types"
return message;
s = input("enter word or integer: ")
while s != "":
print(str_analysis(s))
s = input("enter word or integer: ")
Explanation:
- Check if the string is digit, alphabetical, or mixed inside the function
- Ask the user for the input
- Call and print the result of the <em>str_analysis</em> function inside the while loop
- Keep asking for the input until the given string is empty
Answer:
a tactile input device
Explanation:
Based on the scenario being described it can be said that the best assistive technology for Bernard would be a tactile input device. Such a device would allow Bernard to physically interact with the print on the chalkboard or overhead screen from the device itself without having to actually get close to the chalkboard or screen. Thus allowing him to view its content from the palm of his hand.
