At what rate, in watts, is the Earth losing rotational kinetic energy due to tidal braking? [Hint:The rotational kinetic energy of the earth,Erot=0.5I⊕ω2, where ω= 2π/P is the rotational angular speed,Pbeing the Earth’s rotationalperiod. The moment of inertia of the Earth, I⊕=(2/5)M⊕R⊕2.]
Certain neutron stars (extremely dense stars) are believed to be rotating at about 1 rev/s. If such a star has a radius of 20 km, what must be its minimum mass so that material on its surface remains in place during the rapid rotation?
The evolution of a star depends on its size. If a star is sufficiently large, the gravity forcesholding it together may be large enough to collapse it into a very dense object composed mostlyof neutrons. The density of such a neutron star is about 1014 times that of the earth. Suppose thata star initially had a radius about that of our sun, 7 × 108 km, and that it rotated once every 26 days,as our sun does. What would be the period of rotation (the time for 1 rev) if the star collapsed to aradius of 15 km?
