If you weigh 665 n on the earth, what would be your weight on the surface of a neutron star that has the same mass as our sun and a diameter of 23.0 km ? take the mass of the sun to be ms = 1.99×1030 kg , the gravitational constant to be g = 6.67×10−11 n⋅m2/kg2 , and the acceleration due to gravity at the earth's surface to be g = 9.810 m/s2 .the answer masteringphysics gave me was this. this is over 1011 times your weight on earth! you probably shouldn't venture

F=Gm1m2/r^2  where G is a gravitational constant

F≈m

the greater the mass of planets, the greater the gravitation force experiment by a person

gravity of a planet (a=GM/r^2)

the larger the mass of planet , the larger the gravity of planet

Weight = mass * gravity of the planet

therefore when neutron star has the same mass as our sun, the mass is larger and the gravity of it will be very large

causes

fossil fuels burn

cities become more industrialized

human population grows worldwide

bacteria that live on the ocean floor are sustained by phytoplankton. phytoplankton, microscopic marine photosynthetic organisms, have a vastly significant role to play not only in the marine food web of which they’re part of, but also on a more global scale. despite their infinitely small size in comparison to other marine organisms, these tiny creatures occupy an immensely important ecological niche: they are the foundation of the marine food web, and as primary producers, play key roles in supporting all other organisms in the marine environment, as well as in the regulation of the earth’s climate through the sequestration of carbon, oxygen production, and other related processes. phytoplankton account for roughly half of all global primary productivity; therefore, their significance extends far beyond the marine environment alone. there is an intriguing sense of irony in the realization that these tiny living beings that often live out their existence unnoticed and undetected by the rest of the world, have such a far-reaching impact on the lives of virtually all other living organisms on the planet, particularly on those in the marine environment. the world that we have become accustomed to has been and is continuously shaped by the workings of these miniscule yet vital “plants of the sea”.

hope this !
