Consider a free particle with v(2) = 0, e > 0 with mass m in a periodic box with length l: (x, t) = 4(1) f(t) = aeikr + be-ikret (1) (a) find k in terms of e and l. (b) the wave function and its derivative must be continuous. since the point x = 0 is identified with x = l, write down the rsulting conditions and calculate the allowed energy levels.

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.
