When an RLC series circuit is connected to a 120 V rms, 48 Hz line, the rms current in the circuit is 9.10 A and the current leads the line voltage by 45°.
(a) Find the average power supplied to the circuit.
(b) What is the resistance in the circuit?
(c) If the inductance in the circuit is 52 mH, find the capacitance in the circuit.
(d) Without changing the inductance, by how much should you change the capacitance to make the power factor equal to 1?
(e) Without changing the capacitance, by how much should you change the inductance to make the power factor equal to 1?
What is the angular velocity of the disk. If a single bit requires 5 µm of length along the motion direction, how many bits/second can the writing head write when it is 3.0 cm from the axis? display all work and explanations.
How many 112 W lightbulbs can you use in a 100 V circuit without tripping a 15 A circuit breaker? (The bulbs are connected in parallel, that means that the potential difference across each lightbulb is 100 V.)
What percentage of the neutrons would not interact if the concrete slab were made 45.0 cm thick? How many centimeters thick would the concrete need to be so that 12.0 per cent of the neutrons are transmitted.
Two meters from the left end is the 500 N washing equipment. Joe is 0.500 m from the right end and weighs 920 N. Given that the scaffold is in rotational and translational equilibrium, illustrate what are the forces on each cable?
