Copper, because it has the lowest specific electrical resistance.
specific electrical resistance aka volume resistivity is a fundamental property of a material that quantifies how strongly that material opposes the flow of electric current. A low resistivity indicates a material that readily allows the flow of electric current.
The source of heart for a (an) close system is electricity.
False
Balanced forces mean that there is no net force acting on the object. therefore, the object will not accelerate.
