Q. A 10.0 resistor, 10.0 mH inductor, and a 110.0 µF capacitor are connected in series to a 50.0 V (rms) source having variable frequency. Find the energy delivered to the circuit during one period if the operating frequency is twice the resonance frequency.
Q. A uniform magnetic field of magnitude 0.078 T passes through a circular area of radius 0.1 m. The magnetic field lines are oriented at an angle of 25 degrees with respect to a line that is normal to the circular area. Calculate the flux through the surface.
A beam of 6 MeV electrons passes through a 400 micro-meter thick silicon detector. Estimate the energy lost by the electrons when crossing 200 micro-meters, 300 micro-meters and the full thickness of the detector.
What is the total flux
A highway curve with a radius of 555 m is banked properly for the car travelling 150 km/h. If a 1650 kg Porshe 928 S rounds the curve at 220 km/h, how much sideways force must the tires exert against the road if the car does not skid.
What approximations or simplifying assumptions must you make in the calculations? (Note: Some of these choices are false because they are wrong physics!)
A loudspeaker of mass 25.0 is suspended the distance of = 2.40 below ceiling by two cables that make equal angles with the ceiling. Each cable has a length of = 2.50. What is the tension in each of cables.
A loudspeaker of mass 22 is suspended a distance of = 1.6 below the ceiling by two cables that make equal angles with the ceiling. Each cable has the length of = 3.10.
The liquid level system shown in the below figure is initially at the steady state with the inlet flow rate at 1 cfm. Calculate the maximum & minimum values of the output.
A rifle with a barrel length of 57 fires an 11 bullet with a horizontal speed of 440. The bullet strikes a block of wood and penetrates to a depth of 12. What resistive force (assumed to be constant) does the wood exert on bullet.
A flat uniform circular disk (radius = 2.40 m, mass = 1.00 x 10^2 kg) is initially stationary. The disk is free to rotate in the horizontal plane about a frictionless axis perpendicular to the center of the disk. A 45.0 kg person, standing 0.95 m fro..
A 1300kg car drives around a flat 190m diameter circular track at 30 m/s. What is the magnitude and direction of net force on the car.
assume that for the couple in, you were told that the girl's mass was two-thirds that of the boy. The boy has a velocity of v = +0.61 m/s. What would be the girl's velocity in this case.
A cosmic-ray proton in interstellar space has an energy of 17.0 MeV and executes a circular orbit having a radius equal to that of Jupiter's orbit around the Sun (7.78 x 10^11 m). What is the magnetic field in that region of space.
