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.
The number of years that will pass before the radius of the Moon's orbit increases by 3.6 x 10^6 m will be 90000000 years.
<h3>How to compute the value?</h3>
From the information given, the orbit of the moon is increasing in radius at approximately 4.0cm/yr.
Therefore, we will convey the centimeters to meter. This will be 4cm will be:
= 4/100 = 0.04m/yr.
Time = Distance / Speed
Time = 3.6 x 10^6/0.04
Time = 90000000 years.

Complete question:
Tidal friction is slowing the rotation of the Earth. As a result, the orbit of the moon is increasing in radius at approximately 4.0cm/y. Assuming this rate to be constant how many years will pass before the radius of the Moon's orbit increases by 3.6 x 10^6
Answer:
Radioisotope -> An atom with an unstable nucleus
Radioactivity -> The spontaneous discharge of energy from an unstable nucleus
Radioactive Decay -> The process by which the nucleus of an unstable isotope changes
