Answer:
True
Explanation:
A different type of habitat exists in the caves. There exist no green plants/producers but still various life forms evolve with in the caves. The major source of nutrients with in the caves is water and intrusion of other organism that led to deposition of food in the form of debris/guano etc. These food deposits are intake by the organisms living in caves leading to start of food cycle. This is very much similar to any other food cycle
K2C03 is Potassium Carbonate. It's a molecule.
Answer:
A system that includes the stone and the earth.
Explanation:
If the system of being dropped from the height of the cliff consists of just the stone alone, then it means that its momentum will certainly undergo changes as it falls freely. However, If the system is now expanded to include not only the stone but also the Earth, then it implies that the momentum of the stone which is in the downward direction will be equal and opposite to the momentum of the Earth in the upwards direction towards the stone. Therefore, the momentum will cancel out and net momentum will be zero.
Answer:
i) R = R₀/ 5
, ii) Req = R₀ / 25, iii) R_series / R_parallel = 25
Explanation:
i) The resistivity of a metal is constant, therefore resistance is
R = ρ L / A
where we can see that cutting the resistance in 5 parts each part has
R = R₀/ 5
where R ose the original resistance.
ii) The equivalent resinification of a parallel resistance is
1 / Req = ∑ 1 / Ri
1 / Req = 5 1/ (R₀ / 5)
1 / Req = 25 / R₀
Req = R₀ / 25
to buy these values we find their relationship
R₀ / 
= 25
iii) the series resistance is
Req = 5 Ri
q = 5 (Ro / 5)
Req = Ro
the relationship between resistance in being and parallel is
R_serie / R_parallel = R₀ / (R₀ / 25)
R_series / R_parallel = 25
