Answer:
How much taller (in m) does the Eiffel Tower become at the end of a day when the temperature has increased by 17°C? Its original height is 324 m and you can assume it is made of steel.
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…
