Answer:
The amount of energy at each trophic level decreases as it moves through an ecosystem. As little as 10 percent of the energy at any trophic level is transferred to the next level; the rest is lost largely through metabolic processes as heat.
Ans.
Water cycle describes a cyclic process that involves circulation of water between the earth's atmosphere, oceans, and land through precipitation, drainage in rivers and streams, and return to the earth's atmosphere by transpiration and evaporation.
During respiration, organisms exhale carbon dioxide and water in the form of vapor that goes back to the atmosphere by evaporation.
Thus, the correct answer is option A).
do you have a question particularly in mind?
Answer:
21.932 kN
Explanation:
Given:
Angular velocity, ω = 1.00 × 10⁵ rev/min
Diameter of the turning rotor = 20.0 cm = 0.2 m
or
Radius, r = = 0.1 m
Mass of the sample = 2.00 g = 0.002 Kg
Now,
Force = mass × ω² × r
Here,
ω = 100000 rev/min
or
ω = rev/sec
or
ω = 1667.67 rev/sec
also,
ω = 1667.67 × 2π = 10471.97 radian/s
Therefore,
force = 0.002 × 10471.97 × 0.1
or
Force = 21932.43 N
or
Force = 21.932 kN
b) No the force would not be different as it does not depend on the axis of rotation as it can be observed in the formula
Force = mass × ω² × r
