Answer:
sucking in <u>air</u> through the <u>turbine.</u>
Explanation:
When an airplane turbine operates, it sucks air through it, compresses the air, causes its pressure to increase in the same way as its temperature and ejects it at high speed through the nozzle-shaped output, creating a high output speed and push force capable of moving the plane horizontally.
Vehicles of the fire department are equipped with water pumps of high pressure, in such a way that, when operating, send a flow of water with high pressure and speed through the hose, this force output of the water is sometimes much greater than the force with which the fireman holds the hose, and hence the difficulty to maneuver the hose.
Now when the fireman points the hose with the water at high pressure and speed coming out of it, into a wall close enough. The Fireman will experience newton's third law in all its splendor, which says that every force of action leads to a reaction, so that the reaction could hurt the fireman operating the hose.
This is because warm water vapor, suspended in the air, transforms back into water droplets as it cools. These small droplets collect on surrounding surfaces and are especially noticeable on materials such as glass since they distort light waves, making the mirror and windows appear foggy or misty
Answer: The partial pressure of 
if the total pressure of the mixture is 3.9 atm is 0.975 atm
Explanation:
According to Raoult's law, the vapor pressure of a component at a given temperature is equal to the mole fraction of that component multiplied by the vapor pressure of that component in the pure state.
where, x = mole fraction of nitrogen in solution = 0.25
= partial pressure of nitrogen = ?
= Total pressure = 3.9 atm
Putting in the values :
The partial pressure of is 0.975 atm
true
Explanation:
because in physiology, respiration is the movement of oxygen from the outside environment to the cells within tissues, and the removal of carbon dioxide in the opposite direction.
Answer:
Abdominal closure
Explanation:
The needle has a higher taper ratio and a lower tip angle which makes it sharper. The sharpness (taper-point) of this needle is neccesssary for smooth penetration of tissues such as subcutaneous layers and abdominal viscera, so as to minimize the potential damage of fascia.
