The thing that happens to the speed of the pulse when you stretch the hose more tightly is that it increases.
<h3>What is wage speed?</h3>
It should be noted that wave speed simply means the distance that a wave travels during a particular time.
It should be noted that higher tension leads to an increase in the speed of the wave.
Therefore, the thing that happens to the speed of the pulse when you stretch the hose more tightly is that it increases.

Answer:
Explanation:
In wheel and axle. …with the system is the velocity ratio, or the ratio of the velocity (VF) with which the operator pulls the rope at F to the velocity at which the weight W is raised (VW). This ratio is equal to twice the radius of the large drum divided by the difference…

Answer:
The orbital speed of this second satellite is 5195.16 m/s.
Explanation:
Given that,
Orbital radius of first satellite ![r_{1}= 8.20\times10^{7}](https://tex.z-dn.net/?f=r_%7B1%7D%3D%208.20%5Ctimes10%5E%7B7%7D%20)
Orbital radius of second satellite ![r_{2}=7.00\times10^{7}\ m](https://tex.z-dn.net/?f=r_%7B2%7D%3D7.00%5Ctimes10%5E%7B7%7D%5C%20m)
Mass of first satellite ![m_{1}=53.0\ kg](https://tex.z-dn.net/?f=m_%7B1%7D%3D53.0%5C%20kg)
Mass of second satellite ![m_{2}=54.0\ kg](https://tex.z-dn.net/?f=m_%7B2%7D%3D54.0%5C%20kg)
Orbital speed of first satellite = 4800 m/s
We need to calculate the orbital speed of this second satellite
Using formula of orbital speed
![v=\sqrt{\dfrac{GM}{r}}](https://tex.z-dn.net/?f=v%3D%5Csqrt%7B%5Cdfrac%7BGM%7D%7Br%7D%7D)
From this relation,
![v_{1}\propto\dfrac{1}{\sqrt{r}}](https://tex.z-dn.net/?f=v_%7B1%7D%5Cpropto%5Cdfrac%7B1%7D%7B%5Csqrt%7Br%7D%7D)
Now, ![\dfrac{v_{1}}{v_{2}}=\sqrt{\dfrac{r_{2}}{r_{1}}}](https://tex.z-dn.net/?f=%5Cdfrac%7Bv_%7B1%7D%7D%7Bv_%7B2%7D%7D%3D%5Csqrt%7B%5Cdfrac%7Br_%7B2%7D%7D%7Br_%7B1%7D%7D%7D)
![v_{2}=v_{1}\times\sqrt{\dfrac{r_{1}}{r_{2}}}](https://tex.z-dn.net/?f=v_%7B2%7D%3Dv_%7B1%7D%5Ctimes%5Csqrt%7B%5Cdfrac%7Br_%7B1%7D%7D%7Br_%7B2%7D%7D%7D)
Put the value into the formula
![v_{2}=4800\times\sqrt{\dfrac{ 8.20\times10^{7}}{7.00\times10^{7}}}](https://tex.z-dn.net/?f=v_%7B2%7D%3D4800%5Ctimes%5Csqrt%7B%5Cdfrac%7B%208.20%5Ctimes10%5E%7B7%7D%7D%7B7.00%5Ctimes10%5E%7B7%7D%7D%7D)
![v_{2}=5195.16\ m/s](https://tex.z-dn.net/?f=v_%7B2%7D%3D5195.16%5C%20m%2Fs)
Hence, The orbital speed of this second satellite is 5195.16 m/s.
