In a series with two resistors, which one has the largest resistance? The resistor with the larger voltage drop and the resistor with the smaller voltage drop?
A 39.0-µF parallel-plate capacitor is connected to a 15.0-V battery. After the capacitor is fully charged, the battery is disconnected without loss of any of the charge on the plates. What would the voltmeter read if the radius of each plate were tri..
A mass is attached to a spring on a frictionless horizontal surface. The mass is pulled to stretch the spring by .1 m and then gently released. A short time later, as the mass passes during the equilibrium position, its speed is 1 m/s.
