Heat pumps are also known as refrigeration units for heating and cooling homes by taking heat from air outside in the winter time and then reversed to take heat out of the inside of a home in the summertime. The Geothermal heat pumps take heat from the ground by way of buried pipes deep in ground with chemicals such as water and glycol or similar and transfers that heat into homes in the winter time.
Heating buildings
Answer:
In the context of the loop and junction rules for electrical circuits, a junction is where three or more wires are joined.
Explanation:
A point where at least three circuit paths meet i.e wires, is referred to as a junction.
Kirchhoff’s circuit laws are two(2) equations first published by Gustav Kirchhoff in 1845. Fundamentally, they address conservation of energy and charge in the context of electrical circuits. One of the laws known as Kirchoff's Current Law deals with the principle of application of conserved energy in electrical circuits. Kirchoff's Current Law states that the sum of all currents entering a junction must equal the sum of all currents leaving the junction.
This basically means, the algebraic sum of currents in a network of conductors(wires) meeting at a point is equal to zero
Gas. I know this because first you will need to do the equator so I will say gas
Answer: 
Explanation:
Given
Charge discharged 
time taken 
Current is given as rate of change of discharge i.e.
Therefore, the average current is
