A0.19-kg stone is held 1.1 m above the top edge of a water well and then dropped into it. the well has a depth of 4.6 m. relative to the configuration with the stone at the top edge of the well, what is the gravitational potential energy of the stone−earth system before the stone is released?

2.048 J

Explanation:

mass of stone, m = 0.19 kg

h = 1.1 m

g = 9.8 m/s^2

Gravitational potential energy, U = m x g x h

U = 0.19 x 9.8 x 1.1

U = 2.048 J

Thus, the potential energy of the stone is 2.048 J.

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 .

if they have a finite resultant
