The unit of current, the ampere, is defined in terms of the force between currents. Two 1.0-meter-long sections of very long wires a distance 2.0m apart each carry a current of 1.0 A
What is the force between them? (If the force between two actual wires has this value, the current is defined to be exactly 1 A.)

what is the pOH of a solution prepared by mixing 0.01 moles of HCL with 25.00 mL of 1.0 methylamine, CH3NH2, and with 15.00 mL of 1.0 M methylammonium chloride, CH3NH3CL? Assume that the volume of the solutions are additive and that Kb= 3.70 x 10^-4 for methylamine. You cant use the Henderson-Hasselbalch equation in solving this problem.

The Carbondale Hospital is considering the purchase of a new ambulance. The decision will rest partly on the anticipated mileage to be driven next year. The miles driven during the past 5 years are as follows:
| Year | 1 | 2 | 3 | 4 | 5 |
|---|---|---|---|---|---|
| Mileage | 3,050 | 3,950 | 3,500 | 3,850 | 3,700 |
a) Using a 2-year moving average, the forecast for year 6= _______ miles (round your response to the nearest whole number).
