Concern an electric dipole in an electric field. Clinical studies suggest that an oscillating electric field can disrupt rapidly dividing tumor cells. Dividing cells form a structure called the mitotic spindle that is composed primarily of microtubules. Microtubules have a large electric dipole moment, and it is hypothesized that the response of the microtubules to an oscillating electric field interferes with cell division. (Figure 1) shows an electric dipole in a nonuniform electric field. Figure 1 of 1 Part A The dipole will rotate to a position in which the net torque is zero. Once in this position, Othere is no net force. Othere is a net force to the left. Othere is a net force to the right. Submit Request Answer Provide Feedback ▼

Choose the correct answer. Inserting a dielectric material between two charged parallel conducting plaes, originally separated by air and disconnected from a battery, will produce what effecr on the capacitor?  Choices: increase charge decrease charge increase capacitance decrease capacitance

You use an electrical generator with a hand crank to power a small radio. While cranking, you note the voltage reading measured across a capacitor that is used to store all the energy you're cranking out using your muscles. After an hour, you see the voltage reading is 2.2V. The capacitor has a capacitance of 3.5 x10-6F. You averaged 3.4 rotations on the crank every second. How much energy did your muscles donate to the radio's capacitor? (Give your answer in x10-6J)
