A magnetar is a type of very highly magnetized neutron star. A typical mass is M-2.5Msal,...
A neutron star is an extremely dense, rapidly spinning object that results from the collapse of a massive star at the end of its life. A neutron star with 2.3 times the Sun's mass has an essentially uniform density of 4.8× 10^17 kg/m^3. Part A What's its rotational inertia? Assume the star is a solid sphere. Express your answer with the appropriate units. Part B The neutron star's spin rate slowly decreases as a result of torque associated with magnetic...
Consider a very (infinitesimally!) thin but massive rod, length L (total mass M), centered around the origin, sitting along the x-axis. (So the left end is at (-L/2, 0,0) and the right end is at (+L/2,0,0) Assume the mass density λ (which has units of kg/m)is not uniform, but instead varies linearly with distance from the origin, λ(x) = c|x|. a) What is that constant “c” in terms of M and L? What is the direction of the gravitational field...
