I honestly think A. Predators never benefit prey populations, cause if they are eating the organism population decreases.
Answer:
Since I don't know which answer you want and since I could only find a hospital website with anything related to your question I'll just give you the definitions
Explanation:
<u>Flaccid</u>: ADJ.
(of part of the body) soft and hanging loosely or limply, especially so as to look or feel unpleasant.
(of plant tissue) drooping or inelastic through lack of water.
lacking force or effectiveness.
<u>Tagged</u>: Past-tense ADJ.
attach a label to.
add to something, especially as an afterthought or with no real connection.
Answer:
d) 2v
Explanation:
Since, root mean square speed of a molecule,
![V_{rms}=\sqrt{\frac{3kT}{m}}](https://tex.z-dn.net/?f=V_%7Brms%7D%3D%5Csqrt%7B%5Cfrac%7B3kT%7D%7Bm%7D%7D)
Where,
k = Boltzmann constant,
T = temperature of gas,
m = mass of molecule,
Also, the temperature of a gas,
![T=\frac{pV}{nR}](https://tex.z-dn.net/?f=T%3D%5Cfrac%7BpV%7D%7BnR%7D)
Where,
p = pressure of the gas,
V = volume,
n = number of moles of gas,
R = universal gas constant,
![\implies V_{rms}=\sqrt{\frac{3kpV}{mnR}}](https://tex.z-dn.net/?f=%5Cimplies%20V_%7Brms%7D%3D%5Csqrt%7B%5Cfrac%7B3kpV%7D%7BmnR%7D%7D)
If V = 2V and p = 2P
Then,
![V_{rms}=\sqrt{\frac{12kpV}{mnR}](https://tex.z-dn.net/?f=V_%7Brms%7D%3D%5Csqrt%7B%5Cfrac%7B12kpV%7D%7BmnR%7D)
![=2\sqrt{\frac{3kpV}{mnR}](https://tex.z-dn.net/?f=%3D2%5Csqrt%7B%5Cfrac%7B3kpV%7D%7BmnR%7D)
Hence, if rms speed of a gas molecule under initial conditions is v then rms speed of a molecule will be 2v
i.e. option d is correct.
