Three identical stars each of mass μ are at the vertices of an equilateral triangle of side α that moves in a circular orbit of radius ρ. For each of the stars, the needed centripetal force is provided by the gravitational force due to the other stars. What is the period of such a star system?

Using your knowledge of spheres and gravitation, estimate the radius of a sphere of p = 3.0 x 103 kg/m3 from which you could throw a golf ball and just have it exceed the gravitational attraction of the sphere. Assume that you are able to throw the golf ball at 30.0 m/s.

The PID control architecture might be popular, but that does not mean it can be used for everything. This question explores when the PID controller is (in)sufficient: when it is too much, when it is "goldilocks", and when it is not enough. Consider a plant given by P'(s)-SaAs n increases, so does the order of the system. (sta)" Let's consider three orders and how PID controller design works for...
