Answer:

Explanation:

Point a is the highest. When it comes to potential energy, the higher you are, the more of it you have. Example, when you are at the top of a hill, you have the most potential energy. When you are at the bottom of the hill, you have the least amount of potential energy, and the most kinetic energy.

Hope this helps!!

Answer:

Granite is Intrusive Igneous.

Explanation:

The key words here are "Deep below the Earth's crust", so that gives you the fact it is intrusive. Anything with magma is also most likely hinting towards Intrusive igneous.

A vertical piston-cylinder device contains water and is being heated on top of a range. During the process, 63 Btu of heat is tr

jolli1 [7]

Answer:

The water would have a change in the energy of 50 BTU

Explanation:

Under the assumption that the piston-cylinder system is a closed system, then the conservation law of the system would be: $E_{in}-E_{out}=E_{change}$ , where $E_{in}$ is all the energy that goes into the system, $E_{out}$ is all the energy that leaves the system and, $E_{change}$ is the change of the energy of the system.
For this case the energy that is feeded to the system is heat: 63 BTU.
There is two ways that energy is leaving this system: 8 BTU of heat as losses through the side walls and, 5 BTU of work done by the vapor on the piston.
Then the change of energy of the system is: $E_{change}=E_{in}-E_{out}=63 BTU-(8BTU+5BTU)=50BTU$ .
