Which substance is most easily grounded?

a. pvc pipe
b. iron nail
c. plastic foam plate
d. rubber tire

The reference point in an electrical circuit to measure voltages is called Earth or Ground; that point is a direct hookup to earth that helps stabilizing electrical currents to prevent high voltage surges.

What makes a substance easily grounded is to be a good energy conductor; metallic objects are generally good energy conductors aka GEM "Ground Enhancement Materials" and they are mostly produced from rocks and minerals. That's why the answer is (B.) Iron Nail.

Explanation:

s the environmental science is a broader field that incorporates many elements of earth and life sciences, whereas ecology is usually more focused on how organisms interact with each other and their surroundings, and often on a very specific population of living things. soo yea

explanation:

increasing transnational kinetic energy. because the transnational kinetic energy formula consists of only two variables, mass and velocity, increasing one of those properties is the only way to increase an object's transnational kinetic energy. increases to mass and velocity, however, do not have the same impact.
