Answer:
Fire extinguishers controls the amount of pollution caused by smoke and burning. Although they have no expiring date, they won't last forever. Extinguishers should work for 5 to 15 years, but fire extinguishers be routinely maintained to make sure they remain effective.

A transmission channel between two communicating DTEs is made up of three sections. The first introduces an attenuation of 16 dB, the second introduces an amplification of 20 dB, and the third introduces an attenuation of 10 dB. Assuming a mean transmitted power level of 400 mW, determine the mean output power level of the channel. (3 points)
Answer:
the mean output power level of the channel is 100.475 mW
Explanation:
Given the data in the question;
for the first section; attenuation
16 = 10log₁₀ 400/P₂
P₂ = 10.0475 mW
For the second section; amplification
20 = 10log₁₀ p₂/10.0475
p₂ = 1004.75 mW
For the third section; attenuation
10 = 10log₁₀ p₂/1004.75
p₂ = 100.475 mW
i.e the mean output power level is 100.475 mW
or better still overall attenuation channel = ( 16 - 20) + 10 = 6dB
so
6 = 10log₁₀ 400/P₂
p₂ = 100.475 mV
the mean output power level of the channel is 100.475 mW

Which of the following analogies best describes the relationship between urban planning and zoning?
Zoning is like a hammer because it is used as a tool for urban planning.
Zoning is like a butterfly because it is the final form of urban planning.
Zoning is like a stop sign because it is an obstacle to urban planning.
Zoning is like an egg because it is the process from which urban planning emerges.
Answer:
Zoning is like a hammer because it is used as a tool for urban planning.
