Will a pair of parallel current-carrying wires exert forces on each other? 1. yes; the wires are electrically charged. 2. no; the magnetic field generated by the currents of the wires does not affect the wires themselves. 3. yes; the magnetic field generated by the current in one wire is perpendicular to the current in the other wire and vise versa. 4. no; the two wires attract each other by

1. study the scenario. the particles in some system are moving around quickly. a few minutes later, the particles are moving, on average, more slowly. how does this change in motion affect the temperature of the system? the temperature of the system did not change. the speed of the particles does not affect temperature, the number of particles affects the temperature.the temperature of the system is lower now than it was initially. faster moving particles result in a higher temperature for the system.the temperature of the system is higher now than it was initially. slower moving particles result in a higher temperature for the system.the temperature of the system did not change. the speed of the particles has no effect on the temperature, only the type of atom affects the temperature.

Unpolarized light passes through three polarizing filters. the first one is oriented with a horizontal transmission axis, the second filter has its transmission axis 25.7° from the horizontal, and the third one has a vertical transmission axis. what percent of the light gets through this combination of filters
