Answer:

Explanation:
Hello.
In this case, since the velocity is computed via the division of the distance traveled by the elapsed time:

The distance is clearly 1743 km and the time is:

Thus, the velocity turns out:

Which is a typical velocity for a plane to allow it be stable when flying.
Best regards.
Many materials produce static charge
The food chain system would also affect it. If the antelopes don't have the right food or a low supply of it they might not stay in that area.
Answer:
B: False
Explanation:
The second law of thermodynamics states that: the entropy of an isolated system will never decrease because isolated systems always tend to evolve towards thermodynamic equilibrium which is a state with maximum entropy.
Thus, it means that the entropy change will always be positive.
Therefore, the given statement in the question is false.
Answer:
Time take to fill the standing wave to the entire length of the string is 1.3 sec.
Explanation:
Given :
The length of the one end
, frequency of the wave
= 2.3 Hz, wavelength of the wave λ = 1 m.
Standing wave is the example of the transverse wave, standing wave doesn't transfer energy in a medium.
We know,
∴
λ
Where
speed of the standing wave.
also, ∴ 
where
time take to fill entire length of the string.
Compare above both equation,
⇒
sec

Therefore, the time taken to fill entire length 0f the string is 1.3 sec.
