Help!! A stationary hockey puck has a mass of 0.18 kg. A hockey player uses her stick to apply a 11 N force over a distance of 0.56 m.
How much work does this force do on the puck?

A 20j
B 0.10j
C 2.0j
D 6.2j
E 34j

6.2j

Explanation:

work done=force × displacement

wd=11N×0.56m

wd=6.16N/m~6.2j

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 .

be subject to a force andchange its motion
