Answer:
The objects must be surrounded by air or water. Two objects at different temperatures are touching one another. Two objects at different temperatures are located close to one another.
Explanation:
Answer:
non-science and if im wrong im sorry just search it in go..ogle
A decrease or increase of a certain population can affect the food chain of an ecosystem
Lets say bugs start dying at a rapid rate in an swamp ecosystem
The frog population would then decrease because they have no bugs to eat
The frog’s predators would then decrease because of the number of frogs to eat are decreasing.
So on and so forth.
Hope this helps!
I believe the answer is: practice
To Be able to walk on his own, his body need to get used on sustaining the weight, and must be repeated over and over again to the point where the he could move the legs along with his body weight without losing any balance and fall over.
The thickness up to which the velocity approaches 99% of the free stream velocity. The distance measured perpendicular to the boundary by which the free stream is displaced on account of the formation of the boundary layer.
<h3>What is displacement thickness in boundary layer theory?</h3>
The displacement thickness for the boundary layer is defined as the distance the surface would have to move in the y-direction to reduce the flow passing by a volume equivalent to the real effect of the boundary layer.
The thickness of the boundary layer represented by δ is arbitrarily defined as that distance from the boundary surface in which the velocity reaches 99% of the velocity of the mainstream.
