Two masses, m1 and m2 are joined by a massless spring and lie on a frictionless horizontal surface. The spring has constant k and unstitched length. Required:
Find the characteristic frequencies and normal coordinates when the system is put in motion.

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 .

your answer is, orbit around the nucleus

conduct current i mean it makes sense
