Examine the scenario. object a has 5 protons and 5 electrons. object b has 5 protons and 7 electrons. which option most accurately describes the net charge on the two objects? object a has a net charge of -5 because it has 5 electrons. object b has a net charge of –7 because it has 7 electrons. object a has a net charge of 0 because the positive and negative charges are balanced. object b has a net charge of +2 because there is an imbalance of charged particles. object a has a net charge of +5 because it has 5 protons. object b has a net charge of +5 because it has 5 protons. object a has a net charge of 0 because the positive and negative charges are balanced. object b has a net charge of –2 because there is an imbalance of charged particles.

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.
