The mass of the rock is 1220 kg. it had 400 j of potential energy as it sits on the hill. calculate the height

If two objects at different te,peraure are in contact with each other what happens to their temperature

Which statements are true concerning mineral formation? check all that apply. the slower the cooling, the larger the crystals. the faster the cooling, the smaller the crystals. crystals formed from magma are smaller than crystals formed from lava. minerals can only form in solutions when the solution is heated deep underground. when a solution cools, elements and compounds leave the solution and crystallize as minerals. minerals formed from hot water solutions can form narrow channels in the surrounding rock.

Iwould appreciate if someone could me.
