Has any planet ever been observed stopping spinning?

Rotation or spinning along a planet's axis is something that comes with the formation of the star system, where planet's orbit. Generally stellar systems and planetary system are fromed due to the collapsing of a dense interstellar clouds, which gives an sudden aid to the planetary system to get an awkward spin.There is no force that causes the planets to rotate. Since most of the planets are spherical in shape most of the rotation comes about from the conservation of angular momentum. Angular momentum is given by L=m*w*r^2 where m is the mass, w is the angular velocity in radians per second, and r is the radius of the circular motion. Due to conservation of angular momentum, if the radius of the orbit decreases, then its angular velocity must increase (as the mass is constant). As a result every planet has a spin.

No, none of the planets known as per discovery has ever stopped spinning or tried to stop its spin.

What are some of the things the US did in Iraq after invading it in 2003?

I have yet to be able to figure out why the U.S. continued to sell arms to Iraq, other than to enrich the stockholders of the large American Ordnance companies at tax payer expense.

Over the next 30 years, what industries will not be fully taken over by technology and still be reliant on human decision making?

Here is my simple answer: technology itself. When all the other industries rely on technology, the choices and decisions of scientists and programmers will matter the most to push the technology industry forward. Of course, this assumes that we will not build a meta-machine that can infinitely improve itself in the next 30 years, but given

Have you ever fallen in love with someone you know you couldn't have or ever be with?

I do believe i can answer this one. You can check out my response below. It is originally from Sean Sydney's answer to Have you ever fallen in love with someone while traveling? What happened afterwards?About two months ago i was travelling around Europe for a month. About two weeks before the trip i
