When an object vibrates, it causes slight changes in air pressure. These air pressure changes travel as waves through the air and produce sound. ... In gases, the higher the velocity of sound, the higher the pitch will be (Remember the "Mickey Mouse" sound when people talk after inhaling helium gas?).
Answer:
Yes, this population lies in Hardy-Weinberg equilibrium as it follows both the principles of Hardy-Weinberg.
Explanation:
Here ,
![f(A)= p=0.575](https://tex.z-dn.net/?f=f%28A%29%3D%20p%3D0.575)
![f(B)= q=0.425](https://tex.z-dn.net/?f=f%28B%29%3D%20q%3D0.425)
As per the first principle of hardy Weinberg, the sum of all the alleles at the locus must be equal to 1.
Thus,
![p+q=1\\0.575+0.425 = 1\\1=1\\](https://tex.z-dn.net/?f=p%2Bq%3D1%5C%5C0.575%2B0.425%20%3D%201%5C%5C1%3D1%5C%5C)
Also, as per the second equation of Hardy Weinberg's equation-
![p^{2} + q^{2} +2pq =1](https://tex.z-dn.net/?f=p%5E%7B2%7D%20%2B%20q%5E%7B2%7D%20%2B2pq%20%3D1)
![(0.575)^2+2(0.575)(0.425)+(0.425)^2=1\\0.3306+ 0.48875+ 0.180625=1\\1=1\\](https://tex.z-dn.net/?f=%280.575%29%5E2%2B2%280.575%29%280.425%29%2B%280.425%29%5E2%3D1%5C%5C0.3306%2B%200.48875%2B%200.180625%3D1%5C%5C1%3D1%5C%5C)
Hence, this population lies in Hardy-Weinberg equilibrium as it follows both the principles of Hardy-Weinberg
One is more active, the other is more passive
Answer:
A rise in temperature increases the kinetic energy and speed of particles; it does not weaken the forces between them. The particles in solids vibrate about fixed positions; even at very low temperatures. Individual particles in liquids and gases have no fixed positions and move chaotically.
