Use the literature and notes to state the incoming radiation (particles) in the fol- lowing spectroscopies, and in each case, state the nature of the atomic transition involved: aes -auger electron spectroscopy rbs - rutherford backscattering spectrometry sims - secondary ion mass spectroscopy xps - x-ray photoelectron spectroscopy xrf - x-ray fluorescence spectroscopy sem-scanning electron μ probe nra - nuclear reaction analysis

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.
