The weight of a star is usually balanced by two forces: the gravitational force, acting inward, and the force created by nuclear reaction, acting outward.
Over a long period of time, the force due to nuclear reactions gets weaker, causing the gravitational collapse of the star and crushing atoms out of
existence. Under such extreme conditions, protons and electrons are squeezed to form neutrons, giving birth to a neutron star. Neutron stars are massively
heavy - a teaspoon of the substance of a neutron star would weigh 100 million metric tons on the Earth.
a) Consider a neutron star whose mass is twice the mass of the Sun and whose radius is 13.3 km. (The mass of the Sun is 1.99-1030 kg.) If it rotates with
a period of 2.57 s, what is the speed of a point on the Equator of this star?
Submit Answer Tries 0/99
b) What is the value of g at the surface of this star?
Submit Answer Tries 0/99
c) Compare the weight of a 1.30-kg mass on the Earth with its weight on the neutron star. How many…
A large ship displace can displace a maximum of 12,000 m3 of sea water, how much load (in kg) can it sustain before sinking? (Density of sea water is 1050 kg/m3)
Balloons are often filled with helium gas because it weighs only about one-seventh of what air weighs under identical conditions. The buoyancy force, which can be expressed as Fb = ? airgVballoon, will push the balloon upward. If the balloon has a diameter of 12 m and carries two people, 70 kg each Using appropriate software, investigate the effect of the number of people carried in the balloon on acceleration. Plot the acceleration against the number of people, and discuss the results Assume the density of air is ? =1.16kg/m3, and neglect the weight of the ropes and the cage
