In what situations do Newton’s laws of motion NOT apply?

In a naive or very general sense, it appears that Newton's combined first and second law, F = ma , does not always work. On a fairground ride such as a merry-go-round, or on a turning bus, unrestrained objects have unexplained horizontal accelerations.

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 .

a) electrical > light, sound, and thermal< < < <

) the mechanical energy of the firefighter moving.< < < < a) electrical > light, sound, and thermal< < < <

c) both a and b.
