Atransformer has 200 turns on the primary and 20 turns on the secondary. the primary is connected to a direct current source of 100 millivolts. the voltage in the secondary coil will be:
a) zero.
b) 10 millivolts.
c) 20 millivolts.
d) 1000 millivolts.

Air is contained in a variable-load piston-cylinder device equipped with a paddle wheel. initially, air is at 400 kpa and 17°c. the paddle wheel is now turned by an external electric motor until 75 kj/kg of work has been transferred to air. during this process, heat is transferred to maintain a constant air temperature while allowing the gas volume to triple. calculate the required amount of heat transfer in kj/kg.

Ne way in which elements differ from each other is the structure of the electron cloud in each element's atoms. in an electron cloud, an electron that is farther away from the nucleus has
