A 67? resistor, an 9.0?F capacitor, and a 36mHinductor are connected in series in an ac circuit.
Part A. Calculate the impedance for a source frequency of 300 Hz.
Part B. Calculate the impedance for a source frequency of 30.0 kHz.
An AC power generator produces 46 A (rms) at 3600 V. The voltage is stepped up to 100000 V by an ideal transformer, and the energy is transmitted through a long-distance power line that has a resistance of 100 . What propotion of the power deliver..
Two small, positively charged spheres have a combined charge of 5.35×10-5 C. If each sphere is repelled from the other by an electrostatic force of 1.00 N
A 220g ball is thrown horizontally at 19.2m/s, As it falls under the influence of gravity, find its final momentum (magnitude) after 1.00s.
Many people mistakenly believe that the astronauts orbiting the earth are "above gravity." Compute the acceleration because of gravity, g, for space shuttle territory, 245 kilometres above the earth's surface (dashed line in sketch). Earth's mass ..
When a-particles with energy of 5MeV are scattered on a thin gold foil, it is found that 10,000 a-particles are scattered at an angle greater than 50o, How many will be scattered between 70o and 80o
The system is released from rest, and the string moves without slipping over pulley. If the larger mass is traveling at a velocity of 2.25 m/s when it has dropped 1m, how much mechanical energy was lost due to friction in the pulley's axle.
A 0.300 kg ball is thrown vertically upward with an initial speed of 16.0m/s. What is the maximum height reached by the ball
Kieran takes off down a 50m high, 10° slope on his jet-powered skis. The skis have a thrust of 320 N. The combined mass of skis and Kieran is 50 kg (the fuel mass is negligible). Kieran's speed at the bottom is 40 m/s. What is the coefficient of k..
Two rocks are thrown off the edge of a cliff that is 15.0 m above the ground. The first rock is thrown upward, at a velocity of +12.0 m/s. The second is thrown downward, at a velocity of 12.0 m/s.
A 2.30-kg object attached to a spring moves without friction (b = 0) and is driven by an external force given by the expression F = 3.40sin (2pi*t), where F is in newtons and t is in seconds. The force constant of the spring is 35.0 N/m.
Three blocks of mass m1=1.0 kg, m2=2.0 kg, and unknown mass m3 are on a frictionless forizontal surface, What is the unknown mass m3
A 3.4-cm-diameter parallel-plate capacitor has a 1.8mm spacing. The electric field strength inside the capacitor is 1.3×105V/m, What is the potential difference across the capacitor
