Answer:
INCREASES, BECAUSE ITS ANGULAR MOMENTUM IS CONSERVED.
Explanation: Interstellar cloud of Hydrogen is an accumulation of Hydrogen gas in the cloud.
As the Interstellar cloud of Hydrogen shrinks (reduces) in size,the rate of rotation of the shrinked Interstellar cloud Increases because its angular momentum is conserved. GASEOUS MOLECULES MAKE UP ABOUT 99% OF THE INTERSTELLAR CLOUD WITH HYDROGEN HAVING ABOUT 90% OF THE VOLUME OF GASES IN THE INTERSTELLAR CLOUD.
Answer:
![x=\frac {kd^{2}}{2(mgsin\theta +\mu_{k}mgcos\theta)}](https://tex.z-dn.net/?f=x%3D%5Cfrac%20%7Bkd%5E%7B2%7D%7D%7B2%28mgsin%5Ctheta%20%2B%5Cmu_%7Bk%7Dmgcos%5Ctheta%29%7D)
Explanation:
From the law of conservation of energy
Energy lost by the spring, W=Kinetic energy gained, KE+Potential energy gained, PE+Work done by friction, Fr
![0.5kd^{2}=0.5mv^{2}+mgLsin\theta+\mu_{k}mgcos\theta x](https://tex.z-dn.net/?f=0.5kd%5E%7B2%7D%3D0.5mv%5E%7B2%7D%2BmgLsin%5Ctheta%2B%5Cmu_%7Bk%7Dmgcos%5Ctheta%20x)
![x(mgsin\theta+\mu_{k}mgcos\theta)=0.5kd^{2}](https://tex.z-dn.net/?f=x%28mgsin%5Ctheta%2B%5Cmu_%7Bk%7Dmgcos%5Ctheta%29%3D0.5kd%5E%7B2%7D)
![x=\frac {kd^{2}}{2(mgsin\theta +\mu_{k}mgcos\theta)}](https://tex.z-dn.net/?f=x%3D%5Cfrac%20%7Bkd%5E%7B2%7D%7D%7B2%28mgsin%5Ctheta%20%2B%5Cmu_%7Bk%7Dmgcos%5Ctheta%29%7D)
The required distance from A to B is ![x=\frac {kd^{2}}{2(mgsin\theta +\mu_{k}mgcos\theta)}](https://tex.z-dn.net/?f=x%3D%5Cfrac%20%7Bkd%5E%7B2%7D%7D%7B2%28mgsin%5Ctheta%20%2B%5Cmu_%7Bk%7Dmgcos%5Ctheta%29%7D)
<span>a = 25-13/6 = 12/6 = 2 m/s^2
Av speed: 25+13/2 = 38/2 = 19 m/sec
Dist = speed * time
19 * 6 = 114 meters</span>
<span>Nuclear energy is cleaner while generating electricity. Nuclear fission provides energy without releasing greenhouse gases such as carbon dioxide. However, nuclear power plants generate significant amounts of radioactive waste. That is why we should not choose nuclear energy over fossil fuel power plants.</span>
