You win a hand- powered fl ashlight as a prize in your school science fair. The fl ashlight has a clear plastic case, so you can look inside to see how it works. When you press the handle, a gray ring spins between two coils of wire. The ends of the wire are connected to the light bulb. So, when you press the handle, the light bulb glows. Explain how an electric current is produced to light the bulb. (Hint: Paper clips are attracted to the gray ring.)

Air is contained in a variable-load piston-cylinder device equipped with a paddle wheel. initially, air is at 400 kpa and 17Β°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.
