The current in the wires of a circuit is 180.0 milliAmps. If the voltage impressed across the ends of the circuit was doubled
and the resistance was one-third the original value, then its
new current would be milliAmps.

Alarge box of mass m is pulled across a horizontal frictionless surface by a horizontal rope with tension t. a small box of mass m sits on top of the large box. the coefficients of static and

Consider an insulating crystal, made up of layers of atoms. what form would you expect the temperature dependence of the phonon heat capacity to approach at extremely low temperatures if the interlayer coupling is i)very strong (rigid coupling), and ii) very weak. explain.

Why is the energy that results from a roller coaster's position at the top of a hill referred to as potential energy?
