Neutron stars are: Low density star remnants with a mass less than the mass of the Sun.

Incredibly small remnants of supermassive stars where the gravitational collapse is halted by neutron degeneracy.

Incredibly big and massive star remnants that expel all neutrons in a supernova explosion. Neutron stars are:

You have a resistor and a capacitor of unknown values. first, you charge the capacitor and discharge it through the resistor. by monitoring the capacitor voltage on an oscilloscope, you see that the voltage decays to half its initial value in 2.70 miss . you then use the resistor and capacitor to make a low-pass filter. what is the crossover frequency fc?
