A 9.00-V battery delivers a current of 1.26 A to the lightbulb filament of a pocket flashlight. (a) How much charge passes through the filament in 1.60 min?
(b) How many electrons pass through the filament?
(c) Calculate the energy delivered to the filament during that time. J
(d) Calculate the power delivered by the battery. .

Nitrogen (n2) undergoes an internally reversible process from 6 bar, 247°c during which pν1.2 = constant. the initial volume is 0.1 m3 and the work for the process is 121.14 kj. assuming ideal gas behavior, and neglecting kinetic and potential energy effects, determine heat transfer, in kj, and the entropy change, in kj/s. show the process on a t-s diagram.
