You lift a 45-n bag of mulch 1.2 m and carry it a distance of 10 m to the garden. how much work was done?

Gravity pulls down.  So horizontal motion doesn't do ANY work against gravity.  You can ignore that part.

The only work done is when you lift the bag.

Work = (force) x (distance)

Work = (45 N) x (1.2 m) = 54 Joules

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 .

i think the answer would be reserve.
