6. RADIOACTIVE DECAY A radioactive element decays exponentially. The decay model is given by the formula
A= Ao e^-0.04463t . A is the amount present after 1 days and Ao is the amount present initially. Assume you are starting
with 50g. How much of the element remains after 10 days? 30 days?

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.

conservation of mass

mass before something happens = mass afterwards
