How do scientists measure changes in the levels of global atmospheric co2?

Explanation:

Changes in carbon dioxide have been measured for many years, their volume is expressed in PPM, the abbreviation of Parts Per Million. It means that of every million molecules that a sample of air in our atmosphere contains, the number expressed in this measure will be co2.

gpe = mass x gravity constant x height or… gpe = mgh

where… mass: measured in kilograms (kg)

gravity: gravity constant on earth = 10.00 m/s2

height: measured in meters (m)

gpe: measured in joules (j) or kilojoules (kj)

how do you solve gpe?

gravitational potential energy (gpe) is the energy an object has because of its position above the. ground.

gpe = mass x gravity constant x height or… gpe = mgh.
