This is really imp q A 0.120 kg, 90.0-cm -long uniform bar has asmall 0.055 kg mass glued to its left end anda small 0.150 kg mass glued to the other end.The two small masses can each be treated aspoint masses. You want to balance thissystem horizontally on a fulcrum placed justunder its center of gravity.How far from the left end should the fulcrumbe placed?(Do not copy the answer from othersite)

I Review I Constants During most of its lifetime, a star maintains an equilibrium size in which the inward force of gravity on each atom is balanced by an outward pressure force due to the heat of the nuclear reactions in the core. But after all the hydrogen "fuel" is consumed by nuclear fusion, the pressure force drops and the star undergoes a gravitational collapse until it becomes a neutron star. In a neutron star, the electrons and protons of the atoms are squeezed together by gravity until they fuse into neutrons. Neutron stars spin very rapidly and emit intense pulses of radio and light waves, one pulse per rotation. These "pulsing stars" were discovered in the 1960s and are called pulsars. Part A = 2.0 x 1030 kg) and size (R 3.5 x 10° m) of our sun rotates once every 35.0 days. After undergoing gravitational collapse, A star with the mass (M the star forms a pulsar that is observed by astronomers to emit radio pulses every 0.100 s. By treating the neutron star as a solid sphere,…
