What is the volume, in ml, of mercury, if it weighs 4.55 kg and has a density of 13.0g/ml?

aquifers are bounded above and below by impermeable rock. the driving force of groundwater movement in confined aquifers is pressure, rather than gravity.

weight of any object is given by

w = m*g

where m is mass of the object and g is the acceleration due to gravity.

for earth the value of g is 9.8 m/s^2 so

w=117.6 n m=12 g=?

117.6=12g => g=9.8 m/s^2

which is the force of gravity on earth.

it would only be the stuff in module eight so you need to study all the lessons in that you also could check the flvs

hope this : )
