Answer:(-4,3)
Explanation: They didn’t show the whole graph so it looks confusing but it’s not.
Answer:
Explanation:
Energy E is conserved:

If v₀ = 22m/s, h₀=0m and h₁=25m:

Solving for v₁:

There is no real solution, because the stone never reaches 25m.
PHysical properties are properties that do not involve changes in the molecular level. In this case, malleability and magnetism are physical.
Chemical properties involve changes to the substance at the molecular level or change its identity. In this case, reacting with oxygen and nonflammability is a chemical property.
