Answer:
The frequency doesn't change. If the wavespeed increases, then the wavelength must also increase ... It's just the distance the wave travels during each complete wiggle.
Step-by-step explanation:
- Sound waves are a type of mechanical wave which requires a material medium for transmission. The transmission of such waves occurs as a result of vibration of particles in the material medium. The faster the vibration of the particles the higher the speed of the sound waves.
- When a sound enters a new medium where the sound travels faster, it means the vibration of particles is high, and the wavelength of the waves increases which means the speed of the wave has increased. The frequency on the other hand will remain constant.
Answer:
![h>11](https://tex.z-dn.net/?f=h%3E11)
Step-by-step explanation:
We have the inequality:
![-2(h-5)](https://tex.z-dn.net/?f=-2%28h-5%29%3C-12)
Solve. Divide both sides by -2. Since we are dividing by a negative, we must flip the inequality sign. Thus:
![h-5>6](https://tex.z-dn.net/?f=h-5%3E6)
Add 5 to both sides:
![h>11](https://tex.z-dn.net/?f=h%3E11)
Therefore, our solution is all numbers greater than 11 .
This means that if we substitute any number greater than 11 into our original inequality, the inequality will be true.
Answer:
C
Step-by-step explanation:
I'm pretty sure it's C because I know that A and B are true. That just leaves C and D. I think I know that D is true. The only one I have no knowledge on is C. Sorry this explanation stinks.
