Answer:
2.0 atoms of K and 1.0 atom of S are needed to form a molecule of potassium sulfide.
Explanation:
- The potassium sulfide has the chemical formula <em>K₂S.</em>
∴ Every 1.0 molecule of K₂S composed of 2.0 atom of K and 1.0 atoms of S.
<u><em>So, 2.0 atoms of K and 1.0 atom of S are needed to form a molecule of potassium sulfide.</em></u>

Kinetic energy increases as an object falls. Increase of speed also increases kinetic energy. The kinetic energy is at zero when an object is not moving
Answer:
Weaker
Explanation:
Since the charges on nucleus and electron are opposite in nature, an attractive force exists between them. It is true in generally, that when objects are made to move closer together in the direction of an attractive force, potential energy decreases (and increases whenever attracting objects are force to move apart).
Answer:
What happens to the wavelength when you increase the rate of vibration (how fast your hand moved back and forth). After increasing the rate of vibration, the wavelength decreased.\
