Aneutron star and a black hole are 3.34 x 1012 m from each other at a certain point in their orbit. the neutron star has a mass of 2.78×1030 kg and the black hole has a mass of 9.94×1030 kg. what is the magnitude of the gravitational attraction between the two?

  F=1.65 x 10²⁶ N

Explanation:

Given that

Distance ,R= 3.34 x 10¹² m

Mass m₁= 2.78 x 10³⁰ kg

Mass ,m₂= 9.94 x 10³⁰ kg

we know that gravitational force F given as

G=Constant

G=6.67 x 10⁻¹¹ Nm²/kg²

Now by putting the values

F=1.65 x 10²⁶ N

Therefore the force between these two mass will be 1.65 x 10²⁶ N.

answer: the rock sample is a sedimentary rock.

explanation:

it is given that:

mass of rock sample, m = 2.7 g

volume of rock sample,

so, density of rock sample will be

since, the density of rock sample is . hence, the rock sample is a sedimentary rock, whose densities varies between .
