The change of air temperature with height is the <span>environmental lapse rate. The correct option among all the options that are given in the question is the second option or option "B". The other choices are incorrect and can be easily negated. I hope that this is the answer that has actually come to your desired help.</span>
Here we can say that the momentum of the system will remain conserved
As here we can see that there is no external force in horizontal direction
so here we can say that
As the person in front throw the ball towards back the canoe will start moving forward direction so that momentum of the system will remain conserved
now after this we can say momentum of ball + canoe + two friends = 0 always
now when the person at the back of the canoe will catch the ball then again due to the concept of momentum conservation we can say that the whole system will again comes to rest
<em>so the canoe will become at rest after the person at the back will catch the ball</em>

Answer:
(a) Kav Ne = Kav Kr = 7.29x10⁻²¹J
(b) v(rms) Ne= 659.6m/s and v(rms) Kr= 323.7m/s
Explanation:
(a) According to the kinetic theory of gases the average kinetic energy of the gases can be calculated by:
(1)
<em>where : is the kinetic energy, k: Boltzmann constant = 1.38x10⁻²³J/K, and T: is the temperature </em>
<u>From equation (1), we can calculate the</u><u> average kinetic energies for the krypton and the neon:</u>
(b) The rms speeds of the gases can be calculated by:
<em>where m: is the mass of the gases and : is the root mean square speed of the gases</em>
For the neon:
For the krypton:
Have a nice day!
<u><em>Answer:</em></u>
Destructive interference
<u><em>Explanation:</em></u>
<u>Interference</u> is a term used to refer to the combination of two waves or their overlap
<u>There are two types of interference:</u>
<u>1- Constructive interference:</u> This happens when the waves overlap/combine to produce a resultant wave with a larger displacement
<u>2- Destructive interference:</u> This happens when the waves overlap/combine to produce a resultant wave with a smaller displacement
Hope this helps :)
