four resistors and a capacitor are connected to an 18 v battery with negligible internal resistance, as shown on the diagram. Initially the capacitor is disconnected from the battery - switch is open.
(a) calculate the net resistance of the circuit.
(b) calculate the current in the 2-ohm resistor.
(c) calculate the current in the 3-ohm resistor.
switch is closed and the current reached constant value.
(d) calculate the charge on the capacitor.
(e) calculate the energy stored in the capacitor.
The efficiency of a knife is 75%. If you push down on the knife with a force of 5 N to cut a piece of cake that is 6 cm thick, how much work is done on the cake
Illustrate what is the difference between a departmental accounting system and a responsibility accounting system? Are the reports of departmental net income and the departmental contribution to overhead useful in assessing a department manager's ..
Two small nonconducting spheres have a total charge of 93.1 ?C. When placed 1.01 m apart, the force each exerts on the other is 11.5 N and is attractive. What is the charge on each?
A vessel whose walls are thermally insulated contains 2.10 of water and 0.450 of ice, all at the temperature of 0 . The outlet of a tube leading from a boiler in which water is boiling at atmospheric pressure is inserted into the water.
Two identical point charges (q = +6.90 x 10-6 C) are fixed at opposite corners of a square whose sides have a length of 0.45m. A test charge (q0 = -3.20 x 10-8 C), with a mass of 5.20 x 10-8 kg, is released from rest at one of the corners of the s..
A 74 kg diver steps off a 14 m tower and drops from rest straight down into the water. If he comes to rest 4.4 m beneath the surface, identify the average resistance force exerted on him by the water.
Monochromatic light ( = 630 nm) strikes a pair of slits at normal incidence, forming a double-slit interference pattern on a screen located 1.20 m from the slits. It shows the interference pattern observed on the screen. What is the slit separatio..
Three equal charges are placed at the corners of an equilateral triangle 0.50 m on a side. What are the magnitude of the force on each charge if the charges are each -4.5×10^-9 C?
While running, a person dissipates about 0.60 J of mechanical energy per step per kilogram of body mass. If a 64 kg person develops a power of 65W throughout a race, how fast is the person running? Assume that a running step is 1.5 m long.
A circular wire loop, with a single turn, has a radius of 14.0 cm. The loop is in a magnetic field that is decreasing at the rate of 0.500 T/s. determine the magnitude of the emf induced in the loop
A metal rod of mass 50 and electrical resistance 0.10 rests on parallel horizontal rails that have negligible electric resistance. The rails are a distance = 10.0 apart. The rails are also connected to the voltage source providing a voltage of = 5..
Jane and John, with masses of 51 kg and 66 kg, correspondingly, stand on a frictionless surface 13m apart. John pulls on a rope that connects him to Jane, giving Jane an acceleration of 0.9m/s2 toward him.
