An inductor (L = 400 mH), a capacitor (C = 4.43 ?F), and a resistor (R = 500 ?) are connected in series. A 50.0-Hz AC source produces a peak current of 250 mA in the circuit.
(a) Calculate the required peak voltage ?Vmax.
(b) Determine the phase angle by which the current leads or lags the applied voltage.
Find the range of wavelengths seen in the hydrogen emission spectrum in the Brackett series. Find the shortest wavelength in the Brackett series
Two bugs are buzzing with the same frequency of 186Hz. One of the bugs is flying away from a stationary observer at 9.0m/s, What is the beat frequency that the observer hears
Two point charges q = 97.0 nC and q = -97.0 nC are in vacuum located on the x axis at - 17.0 cm, calculate the total electric flux through the y-z plane
A 115 granite cube slides down a 35 frictionless ramp. At the bottom, just as it exits onto a horizontal table, it collides with a 235 steel cube at rest.
A block of mass m = 4.2 kg, moving on a frictionless surface with a Vi=2.9m/s speed makes a perfectly elastic collision with a block of mass M at rest. After the collision, the 4.2 block recoils with a speed of 0.9m/s. The mass M is closest to.
A mass of 1.2 kg is attached to a single spring and set into oscillation. The period of the spring oscillation is measured to be 4.80 seconds. What is the phase constant for the oscillation
A shell, fired from a cannon, has a muzzle speed (the speed as it leaves the barrel) of 800 ft/s. The barrel makes an angle of 45o with the horizontal and, for ease; the barrel opening is assumed to be at ground level.
Two identical 1.70kg masses are pressed against opposite ends of a spring of force constant 1.70N/cm, Find the maximum speed of each mass when it has moved free of the spring on a smooth
A satellite is rotating around a planet in a circular orbit. The radius of the orbit to the center of the planet is R = 2.4*107 m, Express the magnitude of the centripetal acceleration of the satellite ac in terms of the speed of the satellite v, an..
Find the surface tension force on water inside a tube and height to which the water rises in the tube.
A circular wire loop of radius 13cm carries a current of 3.66 A. It is placed so that the normal to its plane makes an angle of 34.8° with the uniform magnetic field of magnitude 9.70 T.
An electron and a proton are initially very far apart (effectively an infinite distance apart). They are then brought together to form a hydrogen atom, in which the electron orbits the proton at an average distance of 5.40 10-11 m. What is EPEfina..
