Please help!! I need to label parts of the land Y, M, or O (standing for youngest, middle, oldest) to indicate the relative ages of the rock regions. Determine the relative ages of the rock regions on the map, so that they support the hypothesis that Iceland is spreading apart at a divergent boundary. - You can use each letter more than once

-Place only one label in each box

the plateau is likely to turn into a desert do to corrosion.

a. carbon monoxide from car exhaust

b.particulate matter, such as soot

c.water vapor from a factory smokestack

d.acid rain

these are the answer choices im on that question right now

answer: the potential energy decreases from 379 j to 243 j

explanation:

for the law of conservation of energy, the total energy in a system must be conserved. the total energy of the system is given by the sum of kinetic (k) and potential (u) energy:

e = k + u

the total energy is e=675 j, and this does not change.

initially, the kinetic energy is k=296 j, so the potential energy is

at the end, the kinetic energy is k=432 j, so the potential energy is

so, we see that the potential energy has decreased from 379 j to 243 j.
