What if the frequency is now increased to f = 69 hz, and we want to keep the impedance unchanged? (a) what new resistance should we use to achieve this goal? r = ω (b) what is the phase angle (in degrees) between the current and the voltage now? ϕ = ° (c) find the maximum voltages across each element.

Aboat radioed a distress call to a coast guard station. at the time of the call, a vector a from the station to the boat had a magnitude of 45.0 km and was directed 15.0° east of north. a vector from the station to the point where the boat was later found is = 30.0 km, 15.0° north of east. what are the components of the vector from the point where the distress call was made to point where the boat was found? in other words, what are the components of vector c = b - a?

What are the north and south poles of a solenoid change with?
