54. A recycling center is melting down gold. It starts out at 180C and reaches its melting point at 1080C by absorbing 153,000 J of energy. What
was the mass of the melted gold? Note: Gold has a specific heat of 136
J/kg/°C *

Place several e-field sensors at a few points on different equipotential lines, and look at the relationship between the electric field and the equipotential lines. which statement is true? 1-at any point, the electric field is perpendicular to the equipotential line at that point, and it is directed toward lines of higher voltages. 2-at any point, the electric field is perpendicular to the equipotential line at that point, and it is directed toward lines of lower voltages. 3-at any point, the electric field is parallel to the equipotential line at that point.
