Anumber of studies, including the study of six cities, suggest that the largest particles are the most dangerous because they can invade the body's natural defenses and penetrate deeply into the lungs, becoming a chronic source of irritation. a. true b. false

answer: a) y=-8x+5

a) m= -8

b) m= -2

c) m= 7

d) m= 6

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.
