A12 foot ladder is leaning against a building. the ladder makes a 45 degree angle with the building. how far up the building does the ladder reach?

8 ft. the ladder is twelve feet tall and at a 45 degree angle it would be 8 ft up the building

Answerδh > 0explanationc₆h₆  (s)  → c₆h₆ (l)if you are changing it from a solid to a liquid, you are pretty much melting the solid. this requires heat energy. therefore, the reaction is endothermic (takes in energy); the system enthalpy increases as the reaction proceeds: δh > 0.

No, because shearing causes strike-slip faults and normal faults are caused by tension.
