Answer and Explanation:
The law of conversation of energy states that energy cannot be created or destroyed. The pendulum slows down and stops eventually not because the kinetic energy is destroyed, but it is transferred into sound and heat energy instead because there is air resistance and friction.
Kinetic energy => Gravitational potential energy (Loop but some energy transferring to heat and sound each time)
(D)
Explanation:
This kind of bond where the electrons are transferred is called ionic bond. This bond occurs between a metallic and non-metallic elements. The other kind of bond (covalent) involves the sharing of electrons and this happens between non-metallic elements.
Answer:
what is this I don't understand the question
vinegar has the most amount of hydroxide atoms.
A base is a substance that accepts hydrogen ions. When a base is dissolved in water, the balance between hydrogen ions and hydroxide ions shifts the opposite way.
Answer:
Substances can change phase — often because of a temperature change. At low temperatures, most substances are solid; as the temperature increases, they become liquid; at higher temperatures still, they become gaseous.
