Answer:
it says that matter cannot be created or destroyed so the number of atoms is the same after chemical reactions
Answer:
Explanation:
<u><em>Given:</em></u>
Mass = m = 100 kg
Acceleration due to gravity = g = 1.62 m/s²
<u><em>Required:</em></u>
Weight = W = ?
<u><em>Formula:</em></u>
W = mg
<u><em>Solution:</em></u>
W = (100)(1.62)
W = 162 N
Because the strength of the gravitational forces between two objects
depends on the distance between the objects' centers, and when your
elevation changes, so does the distance between your center and the
center of the Earth.
Mmmm no lo entiendo mucho pero tienes que averiguar cual es en gramos
