Figure 3: Binding Energy vs. Mass Number
1. What would release more energy during a fusion reaction: two HP atoms fusing to He or two Li® atoms
fusing to C^2? Explain. The energy that would release more fusion reaction

In the circuit, the switch s has been open for a long time and r = 125 kohm. it is then suddenly closed. (a) determine the time constant before the switch is closed. s (b) determine the time constant after the switch is closed. _ s (c) let the switch be closed at t = 0. find the current in the switch as a function of time. (use t for time. express your answer in milliamps and seconds.) i(t) =_
