A water line with an internal radius of 6.5 x 10⁻³ m is connected to a shower head that has 12 holes. The speed of the water in the line is 1.2 m/s.
(a) what is the volume flow rate in the line?
(b) At what speed does the water leave one of the holes (effective radius of = 4.6 x 10⁻⁴ m) in the head?
Give your answers in order to three 3 significant digits with the proper units.

a) , b)

Explanation:

a) The volume flow rate in the line is:

b) The speed of the water leaving one of the holes are:

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 .
