You build an LRC series circuit using a 3.00 V AC source (and variable frequency), a 10.0 O resistor, a 10. 0 µF capacitor, and a coil of unknown inductance. You adjust the frequency of the source until the circuit is in resonance, and find that the resonant frequency is 100.0 Hz. What is the inductance of the coil? Show all work.
On a frictionless, horizontal air track, the glider oscillates at the end of an ideal spring of force constant 2.52N/cm. The graph in the acceleration of the glider as a function of time. Find the mass of the glider.
A reading on a Geiger counter of 0.23 mrad/h is based on assuming that the measured radiation is due to cesium-137, How many ?-rays does the person's body absorb every second
A car is traveling north at 17.7m/s. After 12s its velocity is 14.10m/s in the same direction. Find the magnitude and direction of the car's average acceleration.
Moving to the right is postive. A 9.1 g object moving to the right at 17 cm/s makes an elastic head on collision with a 20 g object moving in the opposite direction at 19 cm/s. Find the velocity of the second object after the collision
With a particular grating a doublet of the two wavelengths 731.3 and 732.1 nm is viewed in the third order at 9.3° to the normal and is barely resolved. Find the total width of the rulings in nanometers
A 300-kg load is hung on a wire of length 5.00 m, cross-sectional area 0.200 × 10-4 m2, and Young's modulus 8.00 × 1010 N/m2. What is increase in length of the wire
Place a test lead in one of the big lab magnets and plug both ends in the voltmeter so that it measures voltage on the 200m scale, Explain what will happen after the leads are jerked out of the magnet
The average distance from the earth to the sun is called the astronomical unit (AU). does it obey Kepler's third law
During an initial stage of construction, the beam is not to be bolted to the wall, but to be held in place solely by friction. What is the least coefficient of friction between the beam and the wall for the beam to remain in static equilibrium.
There are two identical, positively charged conducting spheres fixed in space. The spheres are 36.2 cm apart, find the initial charge on each sphere
A child slides down a slide with the 29 degree incline, and at the bottom her speed is precisely half of what it would have been if the slide had been frictionless. Compute the coefficient of sliding between the child and the slide.
