Input (English): The electronic contribution to heat capacity varies with this power of temperature. The Lorentz gamma is raised to this power in the expression for relativistic momentum in terms of velocity. A substance's magnetization is proportional to this power of the H-field strength. The electric potential due to an infinite sheet of charge varies with this power of the distance from the sheet. Electrical resistance varies with this power of a resistor's length, and the gravitational force on an object is proportional to this power of its mass. For 10 points, identify this power, which relates two quantities that are linearly proportional.
Output (English): Science
