An ideal parallel-plate capacitor has a capacitance of  C. If the area of the plates is doubled and the distance between the plates is halved, what is the new capacitance?

Three resistors with resistances of 2.0 Ω, 6.0 Ω, and 12 Ω are connected across an ideal dc voltage source  V as shown in the figure. If the total current through the circuit is  I = 2.0 A, what is the applied voltage  V?

A capacitor  C is connected in series with a resistor  R across a battery and an open switch. If a second capacitor of capacitance 2 C is connected in series with the first one, the time constant of the new  RC circuit will be

To achieve a homogeneous field with high image quality of a 1.5 – 3 T scanner a ppm of _________________ or less is required.

Which type of magnetism produces small negative effects to the external magnetic field?

Sociologists use the term “gender” to refer to:

An actress crossing the stage to accept her Oscar award trips on the hem of her gown, and the audience gasps.  When she reaches the microphone, she jokes that she didn’t have enough time to practice walking in the dress.  The audience laughs, and she continues with her acceptance speech.  What has occurred here?

In Saudi Arabia, men hold virtually all political and economic power.  Even though women may attend universities and have careers, they have very strict laws that limit what they are allowed to do.  This is an example of:

What would be a sociological explanation for differences in test scores among different schools?
