Agiven flow field is defined by streamwise velocity component u = (8x) ft/s and cross-stream velocity component v = (8y) ft/s, where x and y are in feet. calculate the acceleration of a particle located at (x, y) = (2 ft, 1 ft) in this flow field, and state whether the flow is steady or unsteady. (hint: use the material derivative.)

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 .
