A solenoid of length 1.00 cm and radius 0.550 cm has 49 turns. If the wire of the solenoid has 1.65 amps of current, what is the magnitude of the magnetic field inside the solenoid? magnitude of the magnetic field:
Ignoring the weak magnetic field outside the solenoid, find the magnetic energy density inside the solenoid.
magnetic energy density:
J/m3
What is the total magnetic energy inside the solenoid?
total magnetic energy:

The roller coaster from problem #1 then tops a second hill at 15.0 m/s, how high is the second hill? 91.5 m 79.2 m 80.0 m 68.5 m

You have a resistor and a capacitor of unknown values. first, you charge the capacitor and discharge it through the resistor. by monitoring the capacitor voltage on an oscilloscope, you see that the voltage decays to half its initial value in 2.70 miss . you then use the resistor and capacitor to make a low-pass filter. what is the crossover frequency fc?

Aloop of wire is in a magnetic field such that its axis is parallel with the field direction. which of the following would result in an induced emf in the loop? choose all that apply. a loop of wire is in a magnetic field such that its axis is parallel with the field direction. which of the following would result in an induced emf in the loop? choose all that apply. moving the loop outside of the magnetic field region. spin the loop such that its axis does not consistently line up with the magnetic field direction. change the magnitude of the magnetic field. change the diameter of the loop
