Solve the following problems:
Problem A: On a very large distant screen, how many totally dark fringes (indicating complete cancellation) will there be, including both sides of the central bright spot? Solve this problem without calculating all the angles! (Hint: What is the largest that sin? can be? What does this tell you is the largest that m can be?)
Problem B: At what angle will the dark fringe that is most distant from the central bright fringe occur?

An oscillating LC circuit has a current amplitude of 7.10 mA, a potential amplitude of 250 mV, and a capacitance of 200 nF. What is the maximum energy stored in the capacitor
One object is at rest, and another is moving. The two collide in a one-dimensional, completely inelastic collision. In other words, they stick together after the collision and move off with a common velocity.
