True. In order for a chemical reaction between elements/compounds, the atoms within the chemicals must have sufficient energy in order to be able create a reaction.
L=G·d
L=600N·3m=1800J
P=L/Δt=1800J/4s=450W
Answer:
(neutral)
(protons)
(electrons)
Explanation:
Electrons have a negative charge (-) while protons have a positive (+) charge.
Atoms will usually be neutral, which means that there will be no charge.
For an atom to have a neutral charge, protons and electrons must "cancel" each other out. For this to happen, you need to have the same amount of each.
Positive will "cancel" out the negative.
Algorithms are a set of well-defined instructions for carrying out a certain task. It must be sound and complete, while a heuristic is something that helps you look for an answer. Its results are subject to chance. Heuristics only tell you what to look for. Not what to find.
