why does the core of a star collapse after fusion has stopped? the strong nuclear force binds extra material in the core of the star, increasing the density of the core and leads to the collapse of the star. the pressure from the core causes the star to collapse. the gravitational attraction of the material in the star is large enough to overcome the outward radiation pressure from the core. the formation of a black hole pulls additional material into the core, resulting in the collapse of the core.

When an RLC-circuit is connected to a constant voltage E at time t=0, the current I in the circuit can be solved from the differential equation Ld^2I/dt^2+RdI/dt +I/C=0 Where resistance R, inductance L and capacitance C are constants. Solve the equation with the initial conditions I(0)=0 and dI/dt(0)=E/L and assuming that (R/2L)^21/LC
