Answer:
The sound will reach my ear in a shorter time in Scenario 1.
The speed of sound waves in solids is faster than it is in gases.
Explanation:
The sound which is produce due to hitting of metal bar with a drumstick reaches to the ears in short time because sound is a longitudinal wave which requires or needs medium for its propagation from one place to another and in solids the particles of medium are close to each other as compared to air so the sound travels faster in solid materials as compared liquid and gases and takes less time to reach my ears.
Answer:
Reaction 1
Explanation:
Reaction 1 would be the most suitable in this case. This is so because in reference to the question you are wanting to keep the food warm over long periods. So in reference to the data in the chart reaction 1 continues to heat up over long periods of time. However, with the other reactions (2, 3, 4) temperatures vary and some even decrease constantly. Therefore showing that the other reactions are invalid to help reach your goal referencing back to the question.

Answer:
There is a positive relationship between environmental policies and jobs and the economy.
Explanation:
The conclusion of the studies is that environmental policies increase employment in the industrial sector. It is because for reducing pollution, the industries does not use heavy machinery for increasing production so these industries uses labour to maintain its production capacity and for more production more labour is required which decrease the problem of unemployment while economy also increases due to more production of products in the industries.
Heat & Pressure ( So I guess in this answer choices it's " Heat up" )
The reason it's not " melt " because if melting were to take place then that would make Magma, and magma isn't metamorphic rock.
