the organisms would reduce in their population.
The sun is the source of the <span>energy that goes up
a food chain. This energy is converted to biomass by primary producers through photosynthesis.
Through interactions such as predation, this energy goes up the food chain from
the primary, secondary and tertiary consumers.
Therefore, if the sun stopped shining, there would be no energy for the food
chain.</span></span>
9 electrons :) I can't give a sbs explanation but here we go
C. Tripling the length and reducing the radius by a factor of 2 is the change to a pipe would increase the conductance by a factor of 12.
<u>Explanation:</u>
As we know that the resistance is directly proportional to the length of the pipe and it is inversely proportional to the cross sectional area of the pipe.
So it is represented as,
R∝ l /A [ area is radius square]
So k is the proportionality constant used.
R = kl/A
Conductance is the inverse of resistance, so it is given as,
C= 1/R.
R₁ = kl₁ / A₁
R₂ = kl₂/A₂
R₂/R₁ = 1/12 [∵ conductance is the inverse of resistance]
= l₂A₁ / l₁A₂
If we chose l₁/l₂= 3 and A₂/A₁= 4 So R₂/R₁= 1/3×4 = 1/12
So tripling the length and reducing the radius by a factor of 2 would increase the conductance by a factor of 12.
Answer:
It might cave in on itself or collapse because of the change in pressure.
