A 6.50?Fcapacitor that is initially uncharged is connected in series with a 4500resistor and a 505 V emf source with negligible internal resistance.
a) Just after the circuit is completed, what is the voltage drop across the capacitor?
b) Just after the circuit is completed, what is the voltage drop across the resistor?
c) Just after the circuit is completed, what is the charge on the capacitor?
d) Just after the circuit is completed, what is the current through the resistor?
e) A long time after the circuit is completed (after many time constants), what are the values of the preceding four quantities?
A freight train has a mass of 2 multiplied by 107-kg. If the locomotive can exert a constant pull of 12.50 multiplied by 105-N, how long would it take to enhancement the speed of the train from rest to 85.00 km/h.
Runner A is initially 8.6 km west of a flagpole and is running with a constant velocity of 5.2 km/h due east. What will be the distance of the two runners from the flagpole
Under the assumption that the actual acceleration is constant determine the number of times that the wheel rotates in the interval from the initial time to the final time.
A building has two open doors facing the bay. The walls of the building absorb sound well, so multiple reflections can be ignored. Two people are standing a distance L = 150 m from the wall with the open doors, as pictured.
