Two thin converging lenses A and B have focal lengths fA and fB, respectively. Lens A has a shorter focal length than Lens B. A collimated laser beam travels down an optical axis from left to right. How must the two lenses be arranged on the optical axis so that the laser beam emerges from the pair of lenses collimated with an increased diameter

explanation:

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.
