2. For Steps 3, 4, and 5 of the water treatment process, describe the property of the substances in the water that is used to remove each substance from the water. h

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.

mass:

given values:

mass = 0.3 kg.

find the sum of the two horizontal vectors and the sum of the two vertical vectors

isoceles right angled triangle

t = 1/400 h   ⇔ 0.0025 h ⇔ 9s ⇔ 0.15 m

any of the answers are correct.
