Two incoherent sources of sound are at a distance of 20 m from each other. One emits sound at a power of 1 W while the other emits sound at a power of 2 W. If you are at a point on the line between the two sources, how far from the 1 W source must you be in order to hear both sources at the same loudness?

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.
