Nitrogen is the most abundant of the gases present in the atmosphere. 78 percent of the atmospheric air comprises of nitrogen, oxygen makes up for 21 percent and all other gases make up for the remaining one percent. Oxygen is a highly flammable gas and in the absence of nitrogen it would not have been possible to utilize this atmospheric oxygen, hence the presence of nitrogen reduces its flammability and also neutralizes the toxicity of other gases.
The Answer is B) Office of Human Services Emergency Preparedness and Response
30 because v1 - v2 is 30 v1 is 40 v2 is 10
Answer:
The time is
The speed is
Explanation:
From the question we are told that
The height of the cliff is
Generally from kinematic equation we have that
before the jump the persons initial velocity is u = 0 m/s
So
=>
Generally from kinematic equation
=>
=>
Traveling from the first to the second stage in a compressor, air is typically cooled in the heat exchanger (intercooler).
<h3>What is a compressor?</h3>
A compressor can be defined as a mechanical device that is designed and developed to provide power to refrigerators, air conditioners, and other heating or cooling mechanical devices (engines), especially by increasing the pressure on air or other applicable gases.
In a two-stage compressor, air would be partially compressed through isentropic compression, and then cooled in a heat exchanger, which is generally referred to as an intercooler.
In this context, we can infer and logically deduce that traveling from the first to the second stage in a compressor, air is typically cooled in the heat exchanger (intercooler).
