Q1. A 35.0- battery with negligible internal resistance, a 90.0- resistor, and a 1.75 inductor with negligible resistance are all connected in series with an open switch. The switch is suddenly closed. How long after closing switch would the current through an inductor reach one-half of its maximum value?

Q2. A 79.0 kg man is riding in a shopping mall. The escalator moves the man at constant velocity from ground level to the floor above, the vertical height of 4.40m.What is the work completed on the man by the gravitational force and the escalator?
