An earthquake results when is along a fault. a. stress; built up b. force; released c. energy; built up d. energy; released

Option d is correct,

The sudden release of energy results in the seismic waves that shakes the ground vigrously. When two part of rock rubbed to each other then they stick to each other for a while and it stores energy in them and releases that stored energy an thus results in earthquake.

the electrical  conductivity  of asolution  of an electrolyte is measured by determining the resistance of thesolution  between two flat or cylindrical electrodes separated by a fixed distance.

it would be a gas formation
