Answer:
Yes, The overall cost of wiring in addressable fire alarm system is significantly cheaper than the conventional one.But the addressale fire alram system is more reliable than a conventional system.
Explanation:
Conventional systems are hardware-based and use analog technology. where addressable fire alarm use digital technology. addressable system is generally more reliable than a conventional system mainly due to how the different systems are wired. With a conventional system, if a device’s wire is damaged or severed, its signal and the signal of other devices down the line cannot be transmitted to the control panel.
With an addressable system, both ends of the wire connect to the control panel. Therefore, if one end becomes damaged or severed, signals can still reach the control panel through the other end of the loop. In addressable systems, a device can be removed or disabled and it will not affect the other devices in the loop.
Answer:
It will be average (B2:C2)

Answer:
These are the supplies in the list:
[‘pencil’, ‘notebook’, ‘backpack’, ‘pen’, ‘calculator’]
Explanation:
The line return (\n) character will be in the output (so there will be a change of line), but it will NOT be visible as it would have been interpreted as a special character.
So the output will be on 2 different lines, with no \n visible.
If the command would have been: print('These are the supplies in the list:\n', supplies), with single quotes (') instead of double quotes (") then then \n would have been printed but not interpreted as a special character. At least in most computer language. Since we don't know of which language the question refers to, we can't be sure at 100%.
Answer:
The answer is Frequency Spectrum.
Explanation:
The frequency spectrum is range of all component frequencies.It contains all the waves which are as following:-
Gamma Rays
X-Rays
Ultraviolet
Visible light.
Infrared
Micro wave
Radio wave
These all waves have their range of frequencies.The waves that are visible to us is only the visible light.
