Newtons 3.law: Action = Reaction
If a body exerts a force on a rope of 400 N the rope exerts a force on the body of 400N also. So the tension in the rope is 400N. See pictures below.
Answer:
Hemoglobin is a protein (because it's a molecule that's not a living part of the cell but aids in cell processes).
From the definition of the first Law of thermodynamics we know that heat flows from the hottest object to the coldest. What has a refrigerator inside is a refrigerant that is traveling through some heat exchangers, driven by pumps and that allows the exchange of heat between a 'Hot' tank and then transport it to a certain place, eject it and return to extract more heat. In this way the refrigerant removes heat from a hot region to a cold region and heat enters said hot region. Since the heat extracted is greater than that of the medium, the heat from the inside flows outward.
The correct answer is B.
Answer:
upper part of any wave.
Explanation:
we normally define wave motion in term of movement of particles. compressions and rarefaction. rarefaction particles apart , and same as trough ( part of wave above mean line ).
