Question:

The current in a series RLC circuit is minimum when the AC power supply is operating at the circuit's resonant frequency Magnetic field lines can, but do not always form closed loops No matter the frequency, light waves always propagate at a speed of A stationary charged particle can be affected by an external magnetic field, In a mass spectrometer, two particles are launched into a uniform magnetic 2 8 299792458 m/s. 1 via magnetic force field with identical charges and equivalent initial velocities. If two tracks with radii ofr = 0.3 mm and re-0.4 mm, the particle that travelled the path with r is more massive than the particle that travelled the path with r. 6 The loop shown below is connected to a resistor that is outside of the magnetic field. Determine the direction of the induced current through the resistor if the magnetic field is decreasing in strength (magnitude). A. Left to right. B. Right to left. C. There is no induced current. D. Not given enough information. A 25 cm long copper wire is placed in a magnetic field such that the current is running toward the East and the magnetic field is directed toward the North. The current is 10 A. If the wire has a weight of 0.4 N, determine the magnitude of the B-field in order for the wire to float above the surface of the Earth A. 0.61 T B. 1.6 T C. 0.16 T D. Not given enough information FM radio frequencies range from 88 MHz - 108 MHz Determine the range of wavelengths for FM radio frequencies. A. 2.8 mm to S.4 mm B. 2.4 m to 8.8 m C. 2.8 m to S.1 m D. Not given enough information.

If you have any problems with the answer or want me to edit the answer, just let me know in the comments and I will try to get on to it as soon as possible. Do give a positive rating if you think this answer helped.

We are required to do only 4 parts of a question.

1. True, the current in rlc circuit is minimum at resonance which occurs when the inductive and capacitive reactances are equal in magnitude.

2. False, Magnetic field lines will always form closed loops because of the presence of magnetic dipoles and absence of magnetic monopoles.

3. True, because the light waves are made up of photons which move at same speed as i.e speed of light.

4.

False, because magnetic force acts only on the charge having velocity. Since the charge is stationary, no magnetic force will exerted on it.
